A man takes in 0.95 × 107 J of energy each day from consuming food, and maintains a constant weight. what power in watt supplied by the food?

Respuesta :

Given data

*The given energy is E = 0.95 × 10^7 J

*The given time is t = 1 day = (24 × 60 × 60) s = 86400 s

The formula for the power in watt supplied by the food is given as

[tex]P=\frac{E}{t}[/tex]

Substitute the known values in the above expression as

[tex]\begin{gathered} P=\frac{(0.95\times10^7)}{(86400)} \\ =1.09\times10^2\text{ W} \end{gathered}[/tex]

Hence, the power in watt supplied by the food is P = 1.09 × 10^2 W
