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

Respuesta :

Answer:

The answer is [tex]96.851[/tex] watts.

Step-by-step explanation:

According to unit conversion,

[tex]2000\ fCal = 2\times 10^6\ Cal =8.368\times 10^6 J[/tex].

So the average power is [tex]8.368\times 10^6 J[/tex] per day.

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

[tex]8.368 \times 10^6 Joules/day = 96.851\ Joules/second[/tex]
