B. The velocity is increasing because the speed is increasing
Answer:
W
Explanation:
m = mass of water being lited = 18.0 kg
t = time taken to lift the amount of water = 1 min = 60 sec
g = acceleration due to gravity = 9.8 m/s²
h = height to which the amount of water is raised = 3.60 m
P = Power output of the pump
Power output of the pump to lift the water can be given as
Inserting the values
W
