A positive charge of 2.9 is pulled on by two negative charges. One, -2 C, is .05 m to the north and the other, -4 C, is a .027 m to the south. What total force is exerted in the positive charge?

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.

a person with a mass of 106kg has a weight of 1060n

we need to know the time interval during which the force acts. impulse of force = momentum change

its c i just checked it
