Question

A motor can output 194.4 W of power. How many joules of work has it done if it runs for 1.56 minutes?

Answer 1

Step-by-step explanation:

Power= Work/ time

Work = Power×time

but SI unit for time is seconds

Changing 1.56 minutes to seconds,

1.56×60= 93.6 s

this implies that, Work = 194.4 × 93.6

= 18195.84J

Answer 2

303.264

Step-by-step explanation:

Work=Power x time

Work=194.4 x 1.56

Work=303.264
