I just wanna know how we know that the system is closed or not if there are different velocities and acceleration given during some time intervals

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

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
