So for a simple pendulum, we know the period is equaling 2 pi multiplied by the square root of the length of the pendulum divided by g, the acceleration due to gravity.
00:08
And so the length of the pendulum with a period of t would be equalling gt squared divided by 4 pi squared.
00:16
And so for part a, we're on earth with a period of one second.
00:21
So the length would be equaling 9 .8 meters per second squared with a period of 1 .0 seconds, quantity.
00:31
Squared and this would be divided by 4 pi squared where the length is then equaling 0 .25 meters.
00:40
So this would be for earth.
00:45
For part b now we have mars.
00:48
So the length would be equaling 3 .7 meters per second squared multiplied by again 1 .0 seconds quantity squared divided by 4 pi squared.
01:01
And so this is equaling 0 .094.
