So in this question, we really just have to interpret a graph and figure out which of these two graphs represents the information that they gave us.
00:08
The graph looks something like this.
00:10
We have two graphs showing the acceleration caused by gravity and in the vertical axis and then the radius of a comet on the horizontal axis.
00:25
And we're told this is graph one is this lower graph here and graph two is the higher graph.
00:36
And like i said, this is the acceleration caused by gravity in units of g.
00:42
And this is the radius of the comet in units of kilometers.
00:51
And we shouldn't be surprised with this graph because the relationship we expect is that the acceleration be inversely proportional to the radius of the comets squared.
01:05
So really, we just got to look at the values that they give us.
01:10
And when over here, you have one reading they have is 2 .5 kilometers in radius...
