Answer:
C. 10 W.
Explanation:
Hello!
In this case, since the power the person uses to lift the 10-N load is computed by using the formula:
[tex]P=\frac{W}{t}[/tex]
Whereas W is the work and t the time; we can compute the work by multiplying the force applied in 1 m:
[tex]W=10N*1m=10J[/tex]
Now, we divide it by the time to obtain:
[tex]P=\frac{10J}{1s}=10W[/tex]
Since joules over seconds are watts.
Best regards!
