Answer:

0.5 Watts.

Explanation:

We are asked to find amount of power used, when 35 J of work was performed in 70 seconds.

We will use power formula to solve our given problem.


P=(E)/(t), where,

P = Power in watts,

E = Energy used in Jules,

t = Time in seconds.

Upon substituting our given values in above formula, we will get:


P=(35)/(70)


P=(1)/(2)


P=0.5

Therefore, 0.5 Watts of power is used to complete the task.
