What is the relationship between thermal energy, temperature, pressure?

1 answer:

6 0

Answer: When volume is constant, pressure is directly proportional to temperature. When temperature is constant, pressure is inversely proportional to volume. When pressure is constant, volume is directly proportional to temperature.

How can Magnets cause objects to have kinetic energy?

lianna [129]

Answer:

If there is a system of magnets being held in place, there is potential energy. When you let go, the potential energy converts to kinetic energy and the magnets move. Putting the system of magnets close together which creates an opposing force.

What is the potential energy of a 2.3g penny that is held at the top of the cn tower (553m)?

SpyIntel [72]

Answer:

12.46 joules

Explanation:

The formula of potential energy is:

$\displaystyle{E_p = mgh}$

where m is mass, g is gravitational force (9.8 m/s^2) and h is height.

Mass is given to be 2.3 grams.
Gravitational Force is defined as 9.8 m/s^2.
Height is given as 553 meters.

However, mass must be in kilograms (kg) unit so we will be converting the gram to kilogram:

We know that a gram equals to 0.001 kg so 2.3 grams will equal to 2.3 * 0.001 = 0.0023 kg.

Therefore, substitute known information in the formula of potential energy:

$\displaystyle{E_p = 0.0023 \times 9.8 \times 553}\\\\\displaystyle{E_p = 12.46 \ \, \sf{Joules}}$

Therefore, the potential energy is 12.46 joules.
