a) Cumulus is 100% the correct answer
It depends on the angle of the earth, and our point of view. A full moon would occur if we were to be right in front of it.
Not at all. Density on its own is not sufficient
1) 15 / 12 = 1.25 ratio
2) to increase acceleration 1.25 times (with same F, or same engine) you have to lower mass 1.25 times
3) 1515/1.25 = 1212 kg
choose A
Explanation:
Using Kinematics,
we have a = (v - u) / t.
Therefore a = (36m/s - 22m/s) / 5s = 2.8m/s².
