一道英文的物理题,关于功的,
How many kilometers per liter will a car go if its engine is 22% efficient and it encounters an average retarding force of 1000 N at highway speed?Assume the energy content of gasoline is 40 MJ per liter.
How many kilometers per liter will a car go if its engine is 22% efficient and it encounters an average retarding force of 1000 N at highway speed?Assume the energy content of gasoline is 40 MJ per liter.
M是兆,10的6次方.
40*10^6*0.22/1000=8800m , 即 8.8 km .
40*10^6*0.22/1000=8800m , 即 8.8 km .
