Answer:
Explanation:
3000 Calorie = 3000 x 1000 calorie
1 calorie = 4.2 Joule
3000 x 1000 calorie = 4.2 x 3000 x 1000 J
= 12.6 x 10⁶ J
It is taken in one day
time period of one day = 24 x 60 x 60 second
= 86400 s
energy given by this intake in 86400s is 12.6 x 10⁶ J
power = energy / time
= 12.6 x 10⁶ / 86400 J/s
= 145.8 J/s or W
= 145 W.
