When a new 9.0 v battery is connect to a torch, the power emitted by the bulb is 6.0 w. after the battery has run-down somewhat, the internal resistance of the run- down battery is 7.4 ω, what is the power emitted by the bulb now? (you should assume that the resistance of the bulb is independent of the current flowing through it.)

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
