The answer is A.) The ratio of thier masses is always the same
Answer:
a luminous ball of plasma
Answer:
Given,
mass of man = 100 N = 10 kg
height = h = 25m
since the man does not move anything with his force, work done by him is zero
work done on the man = gain in potential energy
P.E=mgh
P.E=10×9.8×25
P.E=2.45KJ
Explanation:
so, potential energy gained by man is 2.45 KJ
Car B, Car C, And Car E Are either speeding up or slowing down
The answer is 3. Internal energy decrease
