Density is the mass of a substance every a unit of volume. Therefore, the formula to count density would be mass/volume. The calculation for this problem should be:
Because there are 1609.34 meters in a mile. 1609.34÷30=53.64 but because you put one at the beginning of the mile it will stay 53 and not round up to 54
The kinetic energy of the wind ==> causes ==> the windmill to turn (mechanical energy) ==> which is used to turn an electric generator ==> which generates electrical energy.
