Solve the problem.
-Power is the time rate of doing work and is commonly measured in watts. Power is given by the formula $\mathrm { P } = \frac { \mathrm { W } } { \mathrm { t } }$ where P is power, W is work (in joules), and t is time in seconds. If 800 watts of power are used in 27 seconds, how much work (in joules) was done?
A) 3 joules
B) 2160 joules
C) 21,600 joules
D) 30 joules

Question

Quizplus · Accepted Answer

Using the formula $ \mathrm{W} = \mathrm{P} \times \mathrm{t} $, we calculate work as $ 800 \, \text{watts} \times 27 \, \text{seconds} = 21,600 \, \text{joules} $.
