Question

which of the following is an example of mechanical energy? the light from the sun. the light from a light bulb. the energy in a ball as it is falling. the heat from a fire. question 2 1 pts which of the following uses electrical energy? a washing machine the sun a cat a plant question 3 1 pts what type of energy is formed when chemical bonds are broken? radiant energy thermal energy light energy chemical energy

Explanation:

• Question 1: Mechanical energy is the sum of kinetic and potential energy. A falling ball has kinetic energy due to its motion, so it is an example of mechanical energy. The light from the sun and a light - bulb is radiant energy, and the heat from a fire is thermal energy.
• Question 2: A washing machine uses electrical energy to operate its motor and other components. The sun is a source of nuclear and radiant energy, a cat and a plant do not use electrical energy in the way a washing machine does.
• Question 3: When chemical bonds are broken, chemical energy is released. Radiant energy is related to electromagnetic waves, thermal energy is related to temperature, and light energy is a form of radiant energy.

Answer:

• Question 1: The energy in a ball as it is falling.
• Question 2: A washing machine
• Question 3: Chemical energy
