Answer:
Power = 21.6 Watts
Explanation:
Power =
Where W = work and t = time.
W = Fs
Where F is force and s is displacement.
29.6N(5.9m) = 174.64J
W = 174.64J
Power =
Power = 21.6 Watts

Answer:
W= 4.89 KJ
Explanation:
Lets take
temperature of hot water T₁ = 100⁰C
T₁ = 373 K
Temperature of cold ice T₂= 0⁰C
T₂ = 273 K
The latent heat of ice LH= 334 KJ
The heat rejected by the engine Q= m .LH
Q₂= 0.04 x 334
Q₂= 13.36 KJ
Heat gain by engine = Q₁
For Carnot engine
Q₁ = 18.25 KJ
The work W= Q₁ - Q₂
W= 18.25 - 13.36 KJ
W= 4.89 KJ
