Which of the following best describes a noncontact force

Answer:

A force that is able to act at a distance best describes a noncontact force.

Explanation:

A non-contact force is a force that is exerted between two objects that are not in contact with each other. It is also the force that comes into play when there is no physical interaction between two objects. Gravity is an example of non-contact force.

Consider a situation where you throw an object into the air. This object reaches the maximum height and falls back to the ground. This is due to the non-contract force(Gravity). Hence a non-contract force is a force that acts at distance. The other examples of non-contact forces are magnetic force,  electrostatic force, nuclear force.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
