Sagot :

Answer:

Bill's motor

Explanation:

Bill's motor lifts a box 0.39 metres in 2 seconds.

Nageen's motor lifts the same box 0.35 metres in 2 seconds.

Power = Work done/time

or

[tex]P=\dfrac{mg\times h}{t}[/tex]

Power of bill's motor,

[tex]P_1=\dfrac{m\times 9.8\times 0.39}{2}\\\\P_1=1.91m\ Watts[/tex]

Power of Nageen's motor,

[tex]P_2=\dfrac{m\times 9.8\times 0.35}{2}\\\\P_2=1.71m\ Watts[/tex]

So, Bill's motor applied more power to the box.
