She should start consuming 2,600 calories a day. That way after she burns off her 600 calories, she is still only consuming and storing 2,000 calories.
There are different reasons why things happens. If differential heating did not occur on earth, then there no global warming or global cooling will take place in the atmosphere.
When the Earth flat surface is facing the sun, all its part of that surface would get the same level of incoming solar radiation but the fact remains that due to the Earth being spherical in shape, sunlight is therefore not distributed evenly over the Earth’s surface and as such all the regions of Earth will be heated to different degrees.
Thus, differential heating of Earth’s surface takes place due to different reasons.

Your answer should be B,C and I think G
The time she spent in contact with the trampoline is 0.1619 seconds.
The objective of this question is to determine for how long she is in contact with the trampoline?
The conservational force is exerted on the trampoline is equivalent to the sum of the potential energy at the highest point and the elastic energy at the lowest point.
∴
From the given information;
Using the Simple Harmonic Motion to determine the time at which she is in contact with the trampoline, we have;
where;
