Answer:
For example, the lowest height in a problem is usually defined as zero potential energy, or if an object is in space, the farthest point away from the system is often defined as zero potential energy. Then, the potential energy, with respect to zero at →r0, r → 0 , is just U(→r). U ( r → )
Explanation:
A model that places earth in the center and has the sun, planets, and other objects orbiting the earth.
Explanation:
The geocentric model is a model that places earth in the center and has the sun, planets and other objects orbiting the earth.
- Based on the geocentric model of the earth, other planetary bodies revolves round the earth.
- The heliocentric model is a stark contrast of the geocentric model.
- In the heliocentric model, the sun is at the center of the solar system.
- This model is now known to be correct.

Answer:
4- A material that transfers heat energy more easily than another material will experience a greater rate of thermal energy loss than an object that does not transfer heat energy easily.
Explanation:
Thermal energy loss has to do with loss of heat energy by a body to another body or its environment. The aim of the process is usually the attainment of thermal equilibrium between the body and its environment.
On a cold day, a material that transfers thermal energy more easily will loose thermal energy faster than an object that does not transfer thermal energy. The rate of heat transfer of a body determines its rate of loss of thermal energy.
