Answer:
Bill's motor power: W_B = F x S / T = F x 0.35 / 2= 0.175F
Nageen's motor power: W_N = F x S / T = F x 0.35 / 1.8 = 0.194F
=> 0.194F > 0.175F => Nageen's motor applied more power to the box than Bill's motor.
Nageen's electric motor has applied more power to the box than Bill's electric motor.
An electric motor is an machine that converts electrical energy into mechanical energy.
The electric motor is of two types. One is the AC motor and other is the DC motor. The AC motor takes alternating current as an input, whereas the DC motor takes direct current.
The principle of an electric motor is based on the current-carrying conductor which produces magnetic field around it. A current-carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
Power is the amount of energy transferred per unit time.
[tex]P = \frac{W}{t}[/tex]
Given:
Bill's motor lifts a box 0.35 metres in 2 seconds.
Nageen's motor lifts the same box 0.35 metres in 1.8 seconds.
The power is given by
[tex]P = \frac{W}{t}[/tex]
[tex]P = \frac{mgh}{t}[/tex]
Power of bill's motor,
[tex]P_{1} = \frac{m*9.8*0.35}{2}\\P_{1} = 1.715m Watts[/tex]
Power of Nageen's motor,
[tex]P_{2} = \frac{m*9.8*0.35}{1.8}\\\\P_{2} = 1.905m Watts[/tex]
As [tex]P_2[/tex]is greater than [tex]P_1[/tex], Nageen's motor apply more power than Bill's motor.
