Answer:
Work and time
Explanation:
(1) Power of a machine is given by :
[tex]P=\dfrac{work\ done}{time\ taken}[/tex]
The work done of a machine is directly proportional to the work done and inversely proportional to the time taken by it.
So, the power of a machine depend on the work done and time taken. The correct option is (c) "work and time".
(2) This part is same as part 1.
i.e. power = work done/ time
or P = W / t
Hence, the correct option is (c) " work and time ".
