- heat is transferred from sun through radiation
- and current through convection
Answer:
Point C
Explanation:
Centripetal acceleration ac is inversely proportional to radius of orbit so it is greatest at point C.
Yes it does.
On the periodic table, tin is #50 and Mercury is # 80.
Answer:
100 newtons
Explanation:
Given,
Jamal pushing a large box by a force, F = 100 N
Work done on the large box is, W = 0
It is because the applied force is less than the force of the friction between the two surfaces.
Yet, there will be a force that is exerted by the large box on Jamal.
According to newton's third law of motion, every action has an equal and opposite reaction. The reaction force is in the direction opposite to the force of action. But, their magnitude remains the same.

Hence, If the action force is 100 N, then the reaction force should be in 100 N
Answer:
They move farther apart
Explanation:
When objects heat up they expand for example heating up a balloon makes it expand
