The correct answer is D where acceleration is function of time.
Explanation:
The force acting on the object is constant.
There is no change in the application of forces.
And we know that Force is the product of acceleration and masses.
Newtons second law: 
Regarding mass we know that it can neither be created nor destroyed.
So in  we have two constant terms, constant divided by constant will give the same result as

So the most appropriate graph where time (t) is changing on  but acceleration doesn't changes is D.

Based on the fact that the student is moved twice as far from the center of the earth, her new weight will be 112.5 N.
<h3>What is her new weight?</h3>
When the student was moved by the same distance from the center of the earth, her weight was halved. 
When she was then moved twice as far, her weight was halved again. 
This means that her new weight is:
= 450 x 1/2 x 1/2
= 450 x 1/4
= 112.5 N.
