From the top of the solitaire, the stone begins to fall freely and at exactly 12 o'clock it passes by the observer at the window, and at 12 o'clock and 1 o'clock next to another observer who is 15 m lower. What is the height of the solitaire in relation to the first observer?

i will answer your question if you answer mine

  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

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch
