Answer:
100.71 cm H2O
Explanation:
In a fluid column barometer, the height of the fluid column is proportional to the pressure. The pressure is by definition:
, where F is a force and A is the area.
In a column barometer the force is given by the weight of the fluid:
, and the mass may be expressed as
, where
is the density and V is the volume.
Replacing this in the pressure definition:

In a constant cross section area column, the volume may be calculated as:
where A is the area and h the height. Replacing this in the previous equation:

Different columns may be over the same pressure, so:

Dividing each part for gravity constant:

And isolating hw:
mm
It is equal to 1007,1 cm.
The specialized type of cell in human eyes which help to detect color, a layer at the back of the eyeball containing cells that are sensitive to light and that trigger nerve impulses that pass via the optic nerve to the brain, that is called a retina.
The number of moles of sodium dichromate from the number of moles of oxygen atoms can be determined through stoichiometry. Using the molecular formula of the compound, Na2Cr2O7, 1 mole of the compound contains 7 moles of oxygen. Hence, 14 moles O2*(1 mole Na2Cr2O7/ 7 mole O2) is equal to 2 moles <span>Na2Cr2O7.</span>
Answer:
Nothing
Explanation:
Thermal energy and heat are mainly related because of the fact that the faster molecules move, the more heat is created. If molecules are vibrating slower, that means that there will be less energy, resulting in less heat. Say I am boiling water. As the temperature increases, the water molecules move faster. Once that water cools, the molecules will be moving really slowly. In conclusion, thermal energy and heat are related because of how fast or slow the molecules move, the more or less heat and energy will be produced. I hoped this helped!
