Question

question 7 (1 point)
listen
what is power?
how strong a person is
the amount of force used
the speed of an object
the rate at which work is done

Explanation:

Power is defined in physics as the rate at which work is done. It is calculated as \(P=\frac{W}{t}\), where \(W\) is work and \(t\) is time.

• "How strong a person is" is a vague description not related to the scientific definition of power.
• "The amount of force used" is just force (\(F\)), and power is not just about force.
• "The speed of an object" (\(v\)) is a measure of how fast an object moves, different from power.

Answer:

The rate at which work is done
