Answer:
let us use the expression v = ./2gS in both the cases.
a) In the first case g = 9.8 m/s^2 and S = 10.3 m.
So v = 14.21 m/s
b) in the second case, g = 1.64 m/s^2 and S = 4.2 m = 3.71 m/s

Answer:
d. Imaginary point through which the resultant force of gravity acts on an object
Explanation:
Gravity acting on all particle points of the object, no matter how small they are. As a combination, the center of gravity would denote a single point which substitutes for all the gravity forces on the object.
They both make a thing go faster and slower but the relationship is force.
It is impossible to reach "absolute zero" as it would require a system containing negative amounts of energy to put the energy into. The universe must conserve entropy and by doing so without the negative system, entropy would decrease which violates the second law of thermodynamics. It is possible to approach absolute 0 but never truly reach it.
