Mrs. Davey pushes a 2-kg Physics Book horizontally against the wallIf the coefficient of friction between the book and the wall is 0.15, with what minimum force must Mrs. Davey use to keep the book from sliding down the wall?

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.
