Question

Bridget is riding her bicycle up a hill. Which statements are correct? Select five options.

Bridget is transferring energy to the bicycle.
The bicycle is using energy to do work.
Bridget has kinetic energy.
The bicycle has potential energy.
Bridget has nuclear energy.
The bicycle has mechanical energy.

Answer 1

Answer:

Except option no 5 all other options are correct.

Answer 2

Options 1, 2, 3, 4, and 6 are correct.

Explanation:

If Bridget is riding her bicycle up a hill the all the given statements are correct except the 5th option.

1. When Bridget pushes the pedals, she is transferring energy to the bicycle.
2. Motion is required to move the bicycle, which creates kinetic energy which in turn requires force. After the work is done, the energy is transferred to the bike which keeps it in constant motion.
3. As the bicycle is moving up the hill and has motion, Bridget is also sitting on the moving bike which provides her kinetic energy.
4. As the bike is constantly moving up and the height from the surface is increasing the potential energy stored in the bike also increases.
5. This option is incorrect because nuclear energy is the energy of the nucleus of an atom.
6. The bicycle also has mechanical energy as it is the energy possessed by any object due to its motion or height. Kinect energy and potential energy are 2 types of mechanical energy.
