Understanding Motor Pump Power and Work Done

What is the power of the motor pump in watts if it is given as 2 kilowatts?

• 1000 watts

• 1500 watts

• 2000 watts

• 2500 watts

How is power expressed in terms of energy and time?

• Joules per minute

• Joules per second

• Watts per minute

• Watts per second

What is the equivalent of one minute in seconds?

• 90 seconds

• 30 seconds

• 45 seconds

• 60 seconds

What is the height to which the pump raises water?

• 20 meters

• 15 meters

• 10 meters

• 5 meters

What is the formula for work done against gravity?

• W = mgh

• W = mh/g

• W = mg/h

• W = gmh

What does 'm' represent in the formula W = mgh?

• Magnitude of force

• Momentum of the object

• Mass of the object

• Motion of the object

How do you calculate the mass of water raised by the pump?

• m = t / p * gh

• m = gh / p * t

• m = p * t / gh

• m = p / t * gh

What is the value of acceleration due to gravity used in the problem?

• 20 m/s²

• 5 m/s²

• 10 m/s²

• 15 m/s²

What is the final mass of water raised by the pump in kilograms?

• 2000 kg

• 1500 kg

• 1200 kg

• 1000 kg

In how many seconds does the pump raise the water to the specified height?

• 45 seconds

• 60 seconds

• 30 seconds

• 90 seconds
