An ideal gas at absolute temperature t is in a uniform gravitational field with acceleration due to gravity g in the negative z-direction. (a) by considering the gravitational potential energy of a molecule, derive an expression for the density of molecules n(z) as a function of height z. (b) how does your expression for n(z) compare with that obtained by writing the condition of hydrostatic equilibrium for a slice of the gas located between heights z and z + dz?

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

1/0.14nm = 10^10/1.4 a lot

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
