Discuss whether or not it is possible to wholly convert a given amount of mechanical energy into thermal energy. Is it possible to wholly convert a given amount of thermal energy into mechanical energy

it is the second option.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

  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
