var cid = '7377982948'; Hence if Ankit takes 9 hrs, Arnav will take 6 hrs. Using the mathematical relationship between velocity, distance, and time is how we find the equivalent distances of light-minutes and light-years in SI units. Determine the order in which the Observer will see the three supernovae based on the time between each supernova and the distance from the Observer star. Mathematically, velocity is often represented by the letter \(v\) as seen in the equation: which means that velocity equals displacement (change of position) divided by time. Their distances are: There are several worked examples below to get you started. As each supernova is seen by the Observer star, their order will be indicated at the bottom, over your selections. The first star explodes at time zero and starts the clock running. Speed:Speed is the rate at which a particular distance is covered by an object in motion. Privacy & Terms. ins.style.display = 'block'; For shorter times, we can again use Greek prefixes, so that a millisecond (ms) is one thousandth of a second. container.style.width = '100%'; The gradient of a distance-time graph represents the speed of an object. When it completes one revolution, the distance covered is 2r and the displacement is zero. Our car is said to have a speed of 60 miles per hour (mph) if it will travel a distance of 60 miles in exactly 1 hour. For example, we can say that the 5 meters per second is a scalar whereas 5 meters per second east is a vector. That means it will take you 2 times longer than if you were traveling at light-speed. Work out the average (mean) time for the first 25 cm, for the second 25 cm, and so on. As we know, speed of stream = 1/2 (Downstream speed Upstream speed). )%2F04%253A_Moving_Through_Space%2F4.01%253A_Relationship_Between_Distance_Speed_and_Time, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), San Francisco State University, Chico State University, & Sonoma State University, DISTANCE, TIME, AND SPEED IN EVERYDAY LIFE, 4.2: Measuring Motion - the Doppler Shift, Lookback Time - Looking Far Away is Looking Back in Time, Kim Coble, Kevin McLin, Janelle Bailey, Anne Metevier, Carolyn Peruta, & Lynn Cominsky, status page at https://status.libretexts.org, You will be able to distinguish among distance, speed, and time, You will be able to convert between various units of time, You will be able to convert between various units of speed, You will be able to perform calculations using the relationship between distance, speed, and time, You will know what alight-yearmeans and how it is related to a year, You will be able to determine the lookback time to various astronomical events, including ones occurring at different distances and times, Solution: \(v\) = 30 miles/1 hour = 30 miles/hour, Speed of a person walking: about 3 miles/hour = 5 km/hour, Speed of our fastest spaceship: 10 miles/second = 16 km/second = 57,600 km/hour, Speed of light: 186,000 miles/second = 300,000 km/second, Half of the speed of light: 93,000 miles/second = 150,000 km/second, Nearest star (Proxima Centauri): 4 light-years, Across the Galactic Disk : 100,000 light-years across.

For example, lets say you drive a car. For example, if two passenger trains are moving in the opposite direction with a speed of X km per hour and Y kilometre per hour respectively. 14 to 30 lakh or more. 3. Students will learn the meaning of an object's position, the difference between distance and displacement and some basic graphing of position vs. time. 4/3 t t = 10 mins = > t = 30 mins, d = 20 km, so the usual speed = 20/30min = 20/0.5 = 40 km/hr. To schedule a conference call or plan a meeting at the best time for both parties, you should try between 9:00 AM and 2:00 PM your time in Athabasca, Canada. The answers to all these questions hinge on one's ability that is to read a graph. Speed, Time and Distance are the three variables that represent the mathematical model of motion as, s x t = d. Formula for speed calculation is Speed = Distance/Time. So the usual time t taken to cover 20 km, can be found as follows. We often find it convenient to measure distances in the Solar System in terms of light-minutes, or even light-hours, the distance light travels in 1 hour. I st. That means the gradient of the displacement-time graph becomes increasingly negative during downward motion. Hours, minutes, and seconds between two times with the cell formatted as "h:mm:ss" by using the TEXT function (4:55:00). The delay due to this reduction is 10 minutes, Thus 1/3 T= 10 and T=30 minutes or 0.5 hour. Communities help you ask and answer questions, give feedback, and hear from experts with rich knowledge. Velocity is a vector. You use the subtraction operator (-) to find the difference between times, and then do eitherof the following: Apply a custom format code to the cell by doing the following: On the Home tab, in the Number group, click the arrow next to the General box, and then click More Number Formats. Shouldn't the x have a arrow above it? It asked you to compare them and rank them. In case 1, 20 km between 100 km and 120 km is covered at \(\left(\frac{3}{4}\right)^{th}\) speed. In 1994, scientists were amazed and thrilled to watch pieces of Comet Shoemaker-Levy 9 hit the planet Jupiter. Since displacement is a vector quantity, why does the quiz not let us place a + before the number? If the direction does change then the two will vary.

Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. Solution: Average speed = Total distance travelled/Total time taken. What is the average speed of the truck? container.appendChild(ins); However, distance and displacement are different concepts. This galaxy is about the same size as ours, but it lies about 2.5 million light-years away. Direct link to Aathithya.M's post What is the rule of dista, Posted 3 years ago. In the center is the Observer star. In mechanics, the derivative of the graph which is of the position vs. time of an object is equal to the object of velocity. Distance-time graph is the plot of distance travelled by a body against time. The rate of velocity that changes over time is known as Acceleration. This shows us how slow or fast a target moves. The conversion of speed, time and distance into various units is given below: \(x\text{ km/hr}=x\times\frac{5}{18}\text{m/sec }\), \(x\text{ m/sec }=x\times\frac{18}{5}\text{ km/hr}\). If the velocity which we talked about is changing then the slope is changing, that is a curved line. Still, if we could somehow violate the laws of physics and see M31 as it is right now, we would see very few differences between now and 2.5 million years ago. When that light started out, human beings (Homo sapiens) did not yet exist as a species. The difference between the two cases is only for the 15 km between 60 and 75. The change in velocity is represented by the area under the acceleration graph. But, in the distance-time graph distance never comes back to zero value, after the ball is projected. This makes all the difference between the 2 graphs for a ball thrown vertically upwards. In case 2, 15 km between 60 and 75 is covered at the usual Speed. In the branch of science which is physics, the term motion is the phenomenon in which an object generally changes its position over time. Similarly, if the slope represents positive acceleration then it is an upward sloping line while a downward sloping line will denote the acceleration as negative. ins.className = 'adsbygoogle ezasloaded'; Total time is practised = 5 hours; therefore the time taken while travelling is 4 hours and returning is 1 hour. For the most distant galaxies, we see them as they were billions of years ago. var slotId = 'div-gpt-ad-physicsteacher_in-box-3-0'; In the given question, the speed of Ankit and Arnav is in a ratio of 80: 120 or 2:3. The final difference between online and distance learning is the intention of the teaching strategy. So, if you go out tonight and find M31 (it can be seen from the northern hemisphere in the late summer or fall if you know where to look), the glow you see will have begun its journey 2.5 million years ago. The ratio between the time taken by them to travel the same distance is, Solution: Ratio of time taken = : : = 12 : 15 : 10. While distance is the length of the actual path between two locations, displacement, on the other hand, is the length of the shortest path between two locations. ins.dataset.fullWidthResponsive = 'true'; As we discussed in Chapter 1, the distances involved in astronomy are so large that special distance units are often used for convenience. That is because any photons that just left the Sun would not arrive for 8 minutes, and until they got here we would have no way to know that the Sun had gone out. Velocity is another term that you will see in the activities below. If you have been driving on the highway for 1 hour and have traveled 30 miles, what is your average speed? Required average speed = (2 50 75)/(50 + 75) = 7500/125 = 60 km/hr. Keep the definitions of time, distance, and speed, and of the relationships between them, in mind as you work through the activities that are presented in the following sections. These are the familiar measurements of years, months, weeks, days, hours, minutes, and seconds. Solutions:As we can recognise that the distance covered is fixed in both cases, the time taken will be inversely proportional to the speed. We generally use light-years to measure distances to other stars in our Galaxy, or even to galaxies beyond our own. The phenomenon motion is mathematically described in terms of distance, displacement, and, Velocity Time Graph Based on Types of Motion, The Characteristic of the Distance-Time Graph, Noting the Positive Velocity and Negative Velocity, Understanding the Speeding Up and Slowing Down, NCERT Solutions for Class 12 Business Studies, NCERT Solutions for Class 11 Business Studies, NCERT Solutions for Class 10 Social Science, NCERT Solutions for Class 9 Social Science, NCERT Solutions for Class 8 Social Science, CBSE Previous Year Question Papers Class 12, CBSE Previous Year Question Papers Class 10. To get the velocity in a displacement-time graph, calculate the slope of the line at any instant which will result in instantaneous velocity. This displays the distance to the star from the Observer star in light-years. In case 1, 20 km between 100 km and 120 km is covered at ( 3 4) t h speed. Solution: In crossing a 270 m long platform, Total distance covered by train = 150 + 270 = 420 m. Speed of train = total distance covered/time taken = 420/15 = 28 m/sec In crossing a 186 m long platform, Total distance covered by train = 150 + 186 = 336 m. Time taken by train = distance covered/speed of train = 336/28 = 12 sec. It can also be taken into note that, the change in velocity over a certain interval of time is equal to the area under the acceleration graph in which case, the velocity does not change which is why there can be no area under the acceleration graph. Direct link to ftalpur12's post What is reference Frame?, Posted 3 years ago. Direct link to Andrew Longner's post x is a vector quantity. Ltd.: All rights reserved. Click Create Assignment to assign this modality to your LMS. Questions related to speed, distance and time include various categories such as straight line, relative motion, circular motion, trains, boats, clocks, races, etc. A scalar quantity with units of. For example, we can say that: a bike which is moving in a straight line which is with a speed which is constant. There are several ways to calculate the difference between two times. Before we can apply the concepts of distance, speed, and time to the Universe, we must understand the specific meaning of each and examine how they are related. The physics velocity is a quantity both the direction and magnitude are needed to define it. The displacement of the ball changes with time as shown by Figure 1.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[320,50],'physicsteacher_in-box-4','ezslot_1',148,'0','0'])};__ez_fad_position('div-gpt-ad-physicsteacher_in-box-4-0'); The gradient of the line in the displacement time graph (Figure l here) represents the velocity of the object.Immediately after leaving the throwers hand, the velocity is positive (velocity is a vector, for upward motion, it is taken as positive here) and large so the gradient of the graph is positive and large.As the ball rises, its velocity decreases so the gradient decreases.At maximum height, its velocity is zero so the gradient is zero. Here \(L_{1},\ L_{2}\) are the lengths of the trains. In case 1, 15 km between 60 and 75 is covered at (2/3)rd Speed. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Obtain the time taken by Arnav to reach Hyderabad if Ankit takes 9 hrs. A light-year is the distance light travels in a vacuum (empty space) in 1 year. Here, the v and d have arrows above them to remind us that they include the direction traveled. The first column gives a physical description of a time span, the second is the measurement of that time span in convenient units, and the third represents the time span expressed in seconds using scientific notation. In a distance-time graph for uniformly accelerated motion, there is a constant acceleration whereas in a velocity-time graph, the velocity changing at a uniform motion, the graph would be a straight line with the slope representing the amount of acceleration. We provide you year-long structured coaching classes for CBSE and ICSE Board & JEE and NEET entrance exam preparation at affordable tuition fees, with an exclusive session for clearing doubts, ensuring that neither you nor the topics remain unattended. But the gradient of the distance-time graph is speed which is scalar. Ankit is driving at 80 kmph while Arnav is operating at 120 kmph. 1. Lets draw or we can say that a graph for motion which is uniform. The next several activities are intended to give you a better understanding of speed and its relation to distance and time. ins.style.width = '100%'; If we see that the velocity is constant then the slope is constant that is a straight line. We have a new and improved read on this topic. Can someone Please simplify this I still do not understand. If the speed of the stream is 2.5 km/hr, how much more time will it take to return back? Intervals of time are usually measured in units that are convenient to the events in our daily lives. Time Calculator: Duration Between Two Times and Dates How many years, months, days, hours, minutes, and seconds are there between two moments in time? The absolute scalar value that is the magnitude which is of velocity is known as the speed which is being a coherent derived unit whose quantity is measured in the SI that is metric system as meters per second m/s or as the base which is SI unit of (ms1). Below is an example of a distance-time graph, if it is a straight horizontal line then the body is stationary, and its speed is zero, if the line is diagonal then it is moving . For more information about how to use these functions, see TEXT function and Display numbers as dates or times. If you have been driving on the highway at 20 miles/hour and have traveled a total of 80 miles, how much time have you been traveling? more to return back. Example 2: A truck covers a distance of 1200 km in 40 hours. Speed of a body is the distance covered by the body per unit time i.e. Direct link to NOTcandy's post I think it's just another, Posted 3 years ago. But in the second half of the distance-time graph, the gradient of it(speed) is increasingly positive. People often forget to include a negative sign, if needed, in their answer for displacement. Light-speed is the rate that light travels through empty space (a vacuum), which is about 3.0 108 m/s or 3.0 105 km/s. This can also be used to determine the numerical value of the acceleration of the object. Hours between two times with the cell formatted as "h" by using the TEXT function (4). We often use the symbol, Change in position of an object. To calculate the average velocity for the whole journey, the total change in displacement has to be divided by the change in time. World Wide Coverage. Direct link to DarshK's post I believe that you could , Posted 2 years ago. When solving for direction and displacement on a position-time graph, how do you know when the values for each will have the same absolute value (or in other words, despite the displacement possibly being negative)? Direct link to Alexa PlayDespacito's post I don't understand the me, Posted 2 years ago. Let us now consider a graph which is a graph of distance-time in which the body is moving with motion which is uniform. It can have the arrow above it, but if it doesn't have one it is still generally understood to be a vector. Time Zone Converter Meeting Planner. In fact, the lookback time for the most distant galaxies goes back to nearly the beginning of the Universe. Distance can be defined as how far apart two objects are in space. Nearby galaxies are tens of millions of light-years away, and the most distant galaxies are billions of light-years distant. are confused when interpreting these types of graphs. The, Location of an object relative to the origin. You must manually apply the custom format "h:mm" to the cell. The rate of change of the distance-time graph confers the points on the velocity-time graph. However, in the previous activity, you were given all of the times in a common unit, seconds. 1. For example, the distance across the disk of the Milky Way Galaxy is about 100,000 light-years, and the nearest major galaxy to ours (Andromeda, or M31) is 2.5 million light-years away. lo.observe(document.getElementById(slotId + '-asloaded'), { attributes: true }); (Did you know that the Universe had a beginning?) Distance traveled is always a non-negative number. i pick 0m and 0s to be right where the animal is currently standing. Example 4: Rahul goes Delhi to Pune at a speed of 50 km/h and comes back at a speed of 75 km/h. The gradient of this line in the distance-time graph represents the speed. Get Daily GK & Current Affairs Capsule & PDFs, Sign Up for Free Now the goal is to determine how much time it would take you to get to various places in the Universe, if you were traveling on foot (if it were possible! The site owner may have set restrictions that prevent you from accessing the site. The time taken by both of them to meet will be identical. The gradient of the displacement-time graph gives us the velocity, whereas the gradient of the distance-time graph gives us the speed of the object. = 0.8 60 = 48 min. Solution: Total time taken = Time taken at a speed of 4 km/h + Time taken at a speed of 5 km/ h, 12/4 + 10/5 = 5 hours [ Time = Distance/Speed] Average speed = Total distance/Total time. To convert a given data from km/hour to m/sec, we multiply by 5/18. In a sense, the finite speed of light turns the entire Universe into a time machine, allowing us to see its history. 1. It is the shortest distance between initial and final point by a moving body. We know that Displacement is the distance in a given direction from a certain point. If there is a speed change and even the direction or both then the object that has a velocity is changing and it is said to be undergoing an acceleration. (The same is true for light-years and years.). As a result, light requires up to about 100,000 years to reach one part of the Galaxy from another part. x is a vector quantity. They determine the difference which is in y-coordinates for these two points that arise. However, if the line is found in both the regions of the graph, that is, crossing from the positive region to the negative or vice versa then the object is considered to have changed directions. (If two trains are moving in the same direction). Furthermore, we can see that only positive velocity values are plotted and corresponding to a motion with velocity which is positive. We are not permitting internet traffic to Byjus website from countries within European Union at this time. Here is a quick take on the differentiating points between the displacement-time graph and the distance-time graph for a ball thrown vertically upwards. Direct link to Midnig8angel's post How far it is from one po. However, if we look at even more distant objects, and that includes all galaxies, then the lookback time is greater. We are seeing it as it was 4 years ago. Explain what the slope of the velocity-time Graph gives? (adsbygoogle = window.adsbygoogle || []).push({}); I think it's just another name for the Coordinate Plane. My teacher is saying that the distance covered will be equal to the area of the trapezium in the graph, but the displacement will be equal to the area of the triangle (with purple hypotenuse). Time is a measure of how long it takes for an event to occur, or its duration. Difference between two cases is only for the 10 kms between 50 and 60. This is a useful skill to have when you are trying to understand how one process or event might relate to another. Parsec is usually accompanied by Greek prefixes, such as kilo (103) and Mega (106), to mean a thousand parsecs or a million parsecs. Sign In, Create Your Free Account to Continue Reading, Copyright 2014-2021 Testbook Edu Solutions Pvt. Hints: Recall that 1 AU = 8.3 light-minutes. Now that we are well aware of the definition of speed, distance and time let us understand the relationship between them. To convert a given data m/sec to km/hour, we multiply by 18/5. \end{align*} \], \[\begin{align*} 1\, \text{light-year} &= (3 10^8 meters/\cancel{second}) (1 \cancel{year} 3.15 10^7\cancel{second}/\cancel{year}) \\[4pt] &= 9.5 10^{15}\, meters \end{align*} \]. Copy the following table to a blank worksheet, and then modify if necessary. Divide the distance by the time. Then their relative speed is given by the formula: On the other hand, if the two trains are travelling in the same direction with the speed of X km per hour and Y kilometre per hour respectively. { "4.00:_Moving_Through_Space_Introduction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.01:_Relationship_Between_Distance_Speed_and_Time" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.02:_Measuring_Motion_-_the_Doppler_Shift" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.03:_Astronomical_Objects_in_Motion" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.04:_Wrapping_It_Up" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.05:_Mission_Report" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "00:_Review_of_Mathematics" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "01:_Size_and_Scope" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "02:_Light" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "03:_Telescopes" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "04:_Moving_Through_Space" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "05:_Moving_Through_Time" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "06:_Measuring_Cosmic_Distances" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "07:_Classical_Physics-_Gravity_and_Energy" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "08:_Dark_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "09:_Special_Relativity" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "10:_General_Relativity" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "11:_Black_Holes" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "12:_Gravitational_Lenses" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13:_The_Expansion_of_the_Universe" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "14:_The_Growth_of_Structure" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15:_The_Cosmic_Microwave_Background" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "16:_The_Early_Universe" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "17:_Dark_Energy_and_the_Fate_of_the_Universe" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Knowls : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, 4.1: Relationship Between Distance, Speed, and Time, [ "article:topic", "license:ccbyncsa", "showtoc:no", "authorname:cominskyetal", "autonumheader:yes2", "licenseversion:40", "cssscreen:ssu" ], https://phys.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fphys.libretexts.org%2FBookshelves%2FAstronomy__Cosmology%2FBig_Ideas_in_Cosmology_(Coble_et_al. 0S to be right where the animal is currently standing and T=30 minutes or 0.5.!
