Emission lines are lines that are made when wavelengths of light are given off by cooling gasestrue or false

False

Explanation:

Emission lines are those waves of light which formed by the energetic photon. As the energy of the emitted photons are high then the gases developed are hotter as compared to the surrounding.

Thus, given statement is false

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
