What volume (in liters) of gasoline has a total heat of combustion equal to the energy obtained in part (a)? (See Section 17.6; the density of gasoline is 900 .)

anonymous · Answer

Total energy supplied by a 12 V, 60 A*h battery = U=QV

U=60*3600*12

Total energy supplied by a 12 V, 60 A*h battery = U=2.592*10^6 J

Time required to charge the battery fully=t =Energy(U)/power

Time required to charge the battery fully=2.592*10^6/0.5*10^3

Time required to charge the battery fully=5184 second

Time required to charge the battery fully=1.44 hour or
1 hour 26 minute 24 second
