Find the equivalent resistance of the following circuit. Find the current through the 5 ohm resistor if the potential difference across the battery is
20 V. Determine the power of the 4 ohm resistor.

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

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
