Abody is thrown vertically upwards. its velocity keeps on decreasing. what happens to its kinetic energy when it reaches the maximum height?

When it reaches the maximum height, it's not moving up any more, and it's getting ready to start moving down. In between, there's an instant there when it's not moving at all. Kinetic energy depends on speed. So at the instant it's not moving, it has no kinetic energy. Zero. Nada.

.) 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
