A ball of mass 2.0 kg is travelling at a speed of 12 m / s. It moves towards an object of mass 3.0 kg which is at rest. The ball hits the object and sticks to it. Which row gives the total momentum, and the speed of both objects immediately after the collision?

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

  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
