prove p = hdg
please give answer if you know
P = Force/Area
= Weight/Area
= Mass × gravitational field strength/Area
= Density × Volume × gravitational field strength/Area
= Density × Area × height × gravitational field strength/Area
P = height × density × gravitational field strength
Hence, P = hdg
The pressure is the force applied on per unit area of an object. It can also be described as the product of height, density, and gravitational field strength.
What is Pressure?Pressure is the force applied perpendicular to the surface area of an object over which that force is applied. Gauge pressure is the pressure that is relative to the ambient pressure on an object. Various units of power are used to express pressure of an object. The SI unit of pressure is Pascal (Pa).
Pressure of an object can be calculated by the formula:
P = Force/Area
P = Weight/Area
P = Mass × gravitational field strength/Area
P = Density × Volume × gravitational field strength/Area
P = Density × Area × height × gravitational field strength/Area
P = height × density × gravitational field strength
Hence, P = h × d × g
Therefore, the pressure of an object can be calculated as the product of height, density, and gravitational field strength.

A diver jumps off of the platform and accelerates towards the water at 9.8 m/s2. The diver has a mass of 54 kg. At what force, will the diver jump into the water?
Answer:
The answer is 529.2 N
Explanation:
The Formula for Force is F=M*A
Force equals mass times acceleration,
The mass is 54kg and you multiply that by the acceleration which is 9.8m/s^2
54*9.8= 529.2N
All you have to do is multiply the two numbers when it comes to finding the force.
Does air defy gravity?
Answer:
If you were to inject air into space what would have happen?
Explanation:
In order for air to defy gravity, it would require atmospheric pressure. But air dosen't defy gravity unless it has the support of atmospheric pressure.

Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory? A) It was not published until his death. B) It was not understood by scientific world. C) It lacked sufficient evidence and explanation. D) It lacked practical examples in supporting theory.
