Question

If 35 J of work was performed in 70 seconds, how much power was used to do this task

Answer 1

Answer:

I believe the answer is 0.5 !

Step-by-step explanation:

The formula for power is:

P = work / time

P = 35J / 70s

P = 0.5

Answer 2

Answer:

0.5 Watts.

Step-by-step explanation:

We are asked to find amount of power used, when 35 J of work was performed in 70 seconds.

We will use power formula to solve our given problem.

$P=\frac{E}{t}$, where,

P = Power in watts,

E = Energy used in Jules,

t = Time in seconds.

Upon substituting our given values in above formula, we will get:

$P=\frac{35}{70}$

$P=\frac{1}{2}$

$P=0.5$

Therefore, 0.5 Watts of power is used to complete the task.
