I think the correct answer is A mark has greater gravitational potential energy
:)
Answer:
a) 60kg
Explanation:
mass is not affected by gravity
Answer:
0.05 m/s (It normally stays the same if no outside forces interferes)
Explanation:
It is 0.05 because of you pay attention to the info, it will say that the momentum ”before” the 2 marbles collision is 0.05 m/s, so it is still 0.05 m/s.
Both the technician are correct.
All the driving force in the universe always flow from the higher body to lower body, until unless acted by external forces. Which means heat always flow from a hotter body to colder body, high pressure always flow to low pressure.
Therefore the both the technician are correct.
