Question

*Please Help!* (There are more than two answers!)

The formula for calculating power is work divided by time (power = work ÷ time). What are two ways of stating the same relationship?
A. work = power ÷ time
B. work = power × time
C. time = work ÷ power
D. time = work × power
E. power = work × time

Answer 1

The answers are b and c

Answer 2

Answer: B. work = power × time

C. time = work ÷ power

Step-by-step explanation:

Given : The formula for calculating power is work divided by time .

i.e. $\text{power}=\dfrac{\text{work}}{\text{time}}$

When we multiply time both sides , we get

$\text{power}\times\text{time}=\dfrac{\text{work}}{\text{time}}\times\text{time}$

$\text{power}\times\text{time}=\text{work}$

i.e. $\text{work}=\text{power}\times\text{time}$

When we divide both sides by Power , we get

$\dfrac{\text{work}}{\text{power}}=\text{time}$

i.e. $\text{time}=\text{work}\div\text{power}$

Hence, the two ways of stating the same relationship :

B. work = power × time

C. time = work ÷ power
