The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.
Answer:
C
Explanation:
Power is work divided by time:
P = W / t
Work is force times distance:
W = F d
Therefore:
P = F d / t
Given that F = 500 N, d = 60 m, and t = 240 s:
P = 500 N * 60 m / 240 s
P = 125 W
Answer is C.
Obkect-C has the greatest acceleration. (And it's negative.)
