Question

Suppose a person eats 2000 food calories on average per day. Note that 1 calorie= 4.184 joules and a food calorie = 1000 calories = 4184 joules. What is the average power of this intake? show work

Answer 1

The answer is
`96.851` watts.

Explanation:

According to unit conversion,

`2000\ fCal = 2* 10^6\ Cal =8.368* 10^6 J`.

So the average power is
`8.368* 10^6 J` per day.

If a day has 24 hours, and each hour has 3600 seconds, the average power in Joules/second (Watts) is

`8.368 * 10^6 Joules/day = 96.851\ Joules/second`
