How much power required to do 100 J of work on an object in 4 seconds?
A.24 Watts
B.25 Watts
C.26 Watts
D.24.5 Watts​


Sagot :

[tex]\tt{\huge{\blue{Explanation:}}}[/tex]

The power of an object doing a work W in a given time t is given by

[tex]\boxed{P = \frac{W}{t}}[/tex]

where:

P = power

W = work

t = time

[tex]\tt{\huge{\red{Solution:}}}[/tex]

Solving for the power

[tex]P = \dfrac{W}{t}[/tex]

[tex]P = \dfrac{\text{100 J}}{\text{4 s}}[/tex]

[tex]\boxed{P = \text{25 W}}[/tex]

Therefore, the answer is B. 25 Watts.
