After 25 minutes, the water in both cups reaches thermal equilibrium. Explain how the student can determine that thermal equilibrium has been reached between the cups.​

Answer

the order for strong to weak forces such as

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

explanation

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 equals just about 6,300 km per hour each day an week

Since the pully is a simple machine so the mechanical advantage is a 1
