Final answer:
The power output of the pump is approximately 120 Watts. Therefore, the correct answer is B) 120 W.
Step-by-step explanation:
Power is defined as the rate at which work is done or energy is transferred. In this case, the power output of the pump can be calculated using the formula:
Power = (force × distance) / time
The force exerted by the pump is the weight of the water lifted, which is given by the formula:
Force = mass × acceleration due to gravity
Substituting the given values into the equations, we have:
Force = 24.0 kg × 9.8 m/s2
Distance = 3.20 m
Time = 1 minute = 60 seconds
Plugging in the values, we can calculate the power:
Power = (24.0 kg × 9.8 m/s2 × 3.20 m) / 60 s ≈ 120 W
