The relationship between energy (E), power (P), and time (t) is
P = E/t
One unit of energy is the kilocalorie, also called the Calorie (with a capital C, which is 1000 calories with a small c!). Suppose your body uses 2000 Calories of energy in one day. What is the power of your body? Include units in your work.

Answer:

The avarage power of the body is 96.898 watts.

Explanation:

We must notice that given definition of power implies a constant consumption of energy, so that we should assume that energy consumption is constant. A Calorie is equal to 4186 joules. If we know that [tex]E = 2000\,Cal[/tex] and [tex]t = 1\,day[/tex], the power of body, measured in watts, is:

[tex]P = \frac{(2000\,Cal)\cdot \left(4186\,\frac{J}{Cal} \right)}{(1\,day)\cdot \left(24\,\frac{h}{day} \right)\cdot \left(3600\,\frac{s}{h} \right)}[/tex]

[tex]P = 96.898\,W[/tex]

The avarage power of the body is 96.898 watts.
