If you were in spaceship and fired a 100kg probe into frictionless space, how much force would have to be Exeter on the probe to keep it going for 1000 years?

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.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
