Question

How much energy has your body used, in joules, if your health device indicates that 450 Calories were burned during your workout? How many Calories are in a dinner containing 3.5 x 10 to the power of 6 joules

Answer 1

Step-by-step explanation:

1 Calorie = 4184 Joules

450 Calories = 450 x 4184 J

= 188.28 x 10⁴ J

3.5 x 10⁶ joules

4184 joules = 1 Calorie

3.5 x 10⁶ joules = 836.52 Calories.
