Two identical spheres are mounted on insulated stands. The first sphere has a charge of –1. The second sphere has a charge of –3. After the spheres touch, what
will the charge on each be?

i think the answer is a, hope this is right, that would be my best guess.

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.
