Gravitational potential energy is

                       (mass) x (gravity) x (height) .

When you see this formula, you should be asking yourself:
"Self !  'Height' above WHAT ?

The answer to that question is:  It doesn't matter.  It can be the height
above anything, as long as you make very clear what the reference
(zero) level is, so that it doesn't change during the course of working
with the problem.

There is no particular level relative to which the gravitational potential
energy must always be measured.

In a large number of cases ... like when the problem involves something
going up and down hills, or roller coasters making loops, or soccer balls
or golf balls being launched ... the reference level for gravitational energy
is the ground, because it's THERE and it's convenient.

But if the action in the problem takes place in an office on the 80th floor
of the Aon building in Chicago, or down in a coal-mine shaft in Kentucky
where da sun don't shan, then the floor of the room you're in would be a
much wiser and more convenient level to adopt as the the zero-reference
level.

There's no law.

I would say that the answer would be MASS.

Energy is transferred by the process of convection from the hot water at the bottom of the tank to the cooler water at the top.
iragen [17]
The transfer of energy means, in convention process, transport of matter. In this case, hot water has lower density than cool water. The water with less density ascends and leaves gaps that are occupied with cooler water "packages".

A ball bounced by a basketball player on the floor bounces back up at her. Newton's First Law Newton's Second Law Newton's Third
taurus [48]

Answer:

Newton's Third Law of Motion

Explanation:

Newton's Third Law of Motion which states that, for every action there is an equal but opposite reaction.

This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.

In this scenario, a ball bounced by a basketball player on the floor bounces back up at her.

According to Newton's Third Law of Motion, the statement above simply means that in every interaction, there is a pair of forces acting on the two interacting objects i.e the ball and floor. The size of the force on the ball equals the size of the force on the floor. These two forces are called action and reaction forces and are the subject of Newton's third law of motion.

Hence, the ball bounced by the basketball player on the floor would bounce back in equal magnitude.

Why do surface winds tend to cross the isobars?
scZoUnD [109]
Geostrophic winds blows parallel to the isobars. That is because the Coriolis force and pressure gradient force ( PGF ) are in balance. But near the surface the friction can act to change the direction of the wind and to slow it down. Coriolis force decreases at the surface and PGF stays the same. The difference in terrain conditions affects how much friction is exerted. Hills and forests force the wind to change direction more than flat areas. Answer: Friction reduces the speed so Coriolis is weakened.
