A truck pushes a mound of dirt 5 meters with a force of 75 newtons. How much work has been done ?

Work = force × distance, assuming that the force is parallel to displacement.

Work L=75×5=375J

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.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
