When a hypothesis is confirmed true by evidence from many experiments, it becomes widely accepted by scientists, and it gets a new name: 'Theory' .
Answer:
so that at temperature C = F, the speed of sound is m/s = ft/s = mi/hr. This calculation is usually accurate enough for dry air, but for great precision one must examine the more general relationship for sound speed in gases.

In a fluid, all the forces exerted by the individual particles combine to make up the pressure exerted by the fluid
Due to fundamental nature of fluids, a fluid cannot remain at rest under the presence of shear stress. However, fluids can exert pressure normal to any contacting surface. If a point in the fluid is thought of as a small cube, then it follows from the principles of equilibrium that the pressure on every side of this unit of fluid must be equal. but if this were not a case, the fluid would move in the directions of the resulting force, So the pressure on a fluid at rest is isotropic.
