Answer:
It takes 6.67 second to finish the task by the machine.
Explanation:
Given that,
Work done by the machine (w) = 500J
Power generated by the machine (P) = 75 watt
The dimension of power is energy divided by time. The "SI unit" of "power" is the "watt" (W), which is equal to "one joule per second" .
[tex]Power=\frac{w o r k}{t i m e}[/tex]
Calculate the time for the given work and power.
[tex]\text { Time }=\frac{\text {work}}{\text { power }}[/tex]
[tex]\mathrm{Time}=\frac{500}{75}[/tex]
Time = 6.67 second
6.67 second long did it take to complete its task.
