Question

The power of a toy car is 24 W. What is the energy consumed by the car in 10 min?

Answer 1

We are given the following information

Power = 24 W

Time = 10 min

We are asked to find the energy consumed by the toy car.

Recall that the energy is given by

`E=P\cdot t`

Where E is the energy, P is the power, and t is the time.

Let us first convert the time from minutes to seconds.

There are 60 seconds in 1 minute.

`t=10\cdot60=600\;seconds`

Now, substitute these values into the above formula.

`\begin{gathered} E=24\cdot600 \\ E=14400\;J \\ E=14.4\;kJ \end{gathered}`

Therefore, the energy consumed by the toy car is 14400 joules or 14.4 kilo joules.
