Sam did 480 j of work when moving a bag with a mass of 38 kg. he did the work in 4 minutes. what was the power output?

a.442 w
b.20 w
c.120 w
d.2 w

Option D is the correct answer.

Step-by-step explanation:

We have expression for power,

Work done, W = 480 J

Time taken, t = 4 minutes = 4 x 60 = 240 seconds.

Option D is the correct answer.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
