The electric motor has an input energy of 50,000 joules each second. the motor transfers 35,000 joules of useful energy each second. calculate the efficiency of the electric motor (show workig out too)

power out to power in less than 100%

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
