Question

How much energy can be obtained from conversion of 4.00 gram of mass? 3.60 times 10^14 J How much mass could this energy raise to a height of 92 m? 3.99 times 10^11 kg If 1 gallon of gasoline contains l.06 times 10^10 J of energy, how many gallons of gasoline has the equivalent amount of energy to 4.00 gram of mass? You do not need to enter the unit.

Answer 1

Part C)

m = 4 g = 0.004 kg

n = number of gallons

e = energy of 1 gallon = 1.06 x 10¹⁰ J

Energy for the mass = Energy of n gallons of gasoline

mc² = ne

(0.004) (3 x 10⁸)² = n (1.06 x 10¹⁰)

n = 33962.3
