Alarge marble is dropped in a graduated cylinder with 35 ml of water in it. the water level increases to 49ml. what is the volume of the marble

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.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
