Question 58

A motorized conveyor belt is used in a warehouse to lift identical packages from the floor to a raised mezzanine.

The operators increase the speed of the motor so that more packages are lifted to the platform in a given time.

How does this change affect the work done against gravity in lifting each package and the useful power output of the motor?

A

Work done against gravity: increases; Useful power output: decreases

B

Work done against gravity: increases; Useful power output: increases

C

Work done against gravity: remains the same; Useful power output: decreases

D

Work done against gravity: remains the same; Useful power output: increases
