Answer:
Q=1670J
Explanation:
Mass of ice: m=5g=0.005kg
Latent heat: lambda=3.34×10⁵J/kg
Heat received by ice: Q=m×lambda
Q=0.005×3.34×10⁵=5×334=1670J
Answer:
15 MW
Explanation:
Work done is a product of force and distance moved.
W=fd where f represnt force while d is distance
Substituting f with 5 kN and 3 000 for d then
W= 5*3000=15000 kW which is equivalent to 15 MW
