Question

To interpret and explore a graph showing the change in the temperature of the universe with time. Part A The horizontal axis of the graph measures the time since the Big Bang in seconds. The extreme left of the horizontal axis, where it meets the vertical axis, is labeled 10^-45 seconds (that is a decimal point followed by 44 zeroes and then a one). If we move along two tick marks to the right on the horizontal axis, it is labeled 10^-35 seconds. By what factor does the time increase from one tick mark on the horizontal axis to the next tick mark toward the right? Part B The vertical axis of the graph measures the temperature of the universe in kelvin. If we move up one tick mark to the next, by what factor does the temperature increase?

Explanation / Answer

Part A)

The first mark is 10-45

   The second tick mark is on 10-40

So time increase by 10-40/10-45 =105 times

Part B)

First tick mark is on 1

second tick mark is on 102

So the temperature increase by 102/1= 102 times
