If a 25jg car accelerates at a speed of 100 m/s^2, what will the force of the car be ? A. 4 m/s^2

B. 125 m/s^2

C. 75 m/s^2

D. 2500 m/s^2

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
