Question

A dietary calorie (CAL) is exactly equal to 1000 cal. If your daily in- take of food gives you 2400 C, what is your intake in joules per day?

Answer 1

Answer:

$\boxed{\text{8 000 000 J/day}}$

Explanation:

Convert Calories to calories and then to joules.

$\text{Intake} = \text{ 2000 Cal} \times \dfrac{\text{1000 cal}}{\text{1 Cal}} \times \dfrac{\text{4.184 J}}{\text{1 cal }} = \textbf{8 000 000 J}\\\\\text{Your intake is \boxed{\textbf{8 000 000 J/day}} }$
