A woman of mass 60kg is standing in a lift at a shopping centre a ) the lift is at rest

1. state the value of the weight of
the woman

2. state the value of the force exerted on the woman by the floor of the lift

b ) the lift accelerates upwards at 2.5 m / s². calculate the force exerted on the woman by the floor when the lift is accelerating

c ) the lift reaches a steady upward speed. state the value of the force exerted on the woman by the floor at this steady speed

answer: (431,2)

step-by-step explanation:

this is poiselle's equation from fluid mechanic in physics. mech eng

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
