Answer:

B) 2.7W

Explanation:

Converting Cal to Joule

        1 cal = 4.186J

        14 kcal = 14 x 1000 x 4.186

                     = 58604 J

Converting hour to seconds

             6 hours = 6 x 60 x 60 seconds

                           = 21600 seconds

Power is the time rate of doing work.

Power = Work/Time

P = (58604) / (21600)

P = 2.7W

Answer:

D) 0.0027

Explanation:

Power is the rate of work that is power = work/time

we are given the following:

Work = 14kcal this is equal to 58.576 J

time = 6hours this is equal to 21600 seconds

therefore:

Power = 58.576/21600 = 0.0027W
