Which of these best describes the difference between a closed and open system and the total energy in the system.
A) Since energy is always conserved, the total energy in both systems remains the same.
B) In a closed system the amount of energy remains the same. In an open system, energy is always released.
C) In a closed system the amount of energy remains the same. In an open system, energy is always absorbed.
D) In a closed system the amount of energy remains the same. In an open system, work is either done on or by the system changing the energy of the system.

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

it is b. absorbs thermal energy
