Suppose a person eats 2000 food calories on average per day. Note that 1 calorie= 4.184 joules and a food calorie = 1000 calorie
Crazy boy [7]

Answer: 0.097\text{\ J/s}

Step-by-step explanation:

Given :  1 calorie= 4.184 joules

A food calorie = 1000 calories = 4184 joules.

Then, 2000 food = 2\times4184=8368 joules   [By Unitary method]

We know that : \text{Power}=\dfrac{\text{Energy}}{\text{Time}}

Since 1 day = 24 hours

and 1 hour = 3600 seconds

Then, 24 hours = 24\cdot3600=86400 seconds.

Now,   \text{Power}=\dfrac{8368}{86400}

=0.0968518518519\approx0.097\text{\ J/s}

Hence, the average power of this intake = 0.097\text{\ J/s}
