Answer:

Explanation:
Gravity on the surface of planet is given as

as we know that


now gravity on the planet is

so we have

now we know that

so we will say



Average velocity is the change in distance divided by the time it takes to travel that distance. so the first one.
Answer: Decreases
Explanation:
By definition, absolute zero temperature defines the temperature at which the atoms of a material no longer transmit thermal energy.
Engineering materials can transmit thermal energy at higher temperatures by random molecular motion.
It follows that as the temperature decreases toward absolute zero, random molecular motion decreases.
Because of the high electricity level would be my guess
