Question

Scenario A: 120 J of work is done in 6 s. Scenario B: 160 J of work is done in 8 s. Scenario C: 200 J of work is done in 10 s. Which scenario uses the most power?

Answer 1

Using the equation P = W/t to solve your problem . 

Thus the answer is all of them use the same amount of power. 20 J.  

Answer 2

Answer:

They all used the same power.

Explanation:

Power is equal to the ratio between the work done (W) and the time taken (t):

$P=\frac{W}{t}$

Let's calculate the power used in the three scenarios:

A) $P=\frac{120 J}{6 s}=20 W$

B) $P=\frac{160 J}{8 s}=20 W$

C) tex]P=\frac{200 J}{10 s}=20 W[/tex]

So, the power used is the same in the three scenarios.
