An engine uses 5 × 106 J of thermal energy. a) If the engine is 40% efficient, how much work can it do?
b) Where did the rest of the thermal energy go?

v=ir = 3x15 =45 v

  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

statement #3 on andre"s list is false.
