Javier Sotomayor set the world record for a high jump at 2.45 m at the 1992 Olympic Games. How long would he be in the air on the moon if he attempted the same jump? The acceleration due to gravity on the moon is g = 1.62 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.

because if the tool that you are using is not balanced it there would be false mass.
