Every action has equal and opposite reaction

0Thank You

Yogita Ingle 3 months ago

Newton’s Third Law of Motion states that there is always reaction for every action in opposite direction and of equal magnitude.

Explanation: Whenever a force is applied over a body, that body also applies same force of equal magnitude and in opposite direction.

Example:

Walking of a person: A person is able to walk because of the Newton’s Third Law of Motion. During walking, a person pushes the ground in backward direction and in the reaction the ground also pushes the person with equal magnitude of force but in opposite direction. This enables him to move in forward direction against the push.
Recoil of gun: When bullet is fired from a gun, the bullet also pushes the gun in opposite direction, with equal magnitude of force. This results in gunman feeling a backward push from the butt of gun.
Propulsion of a boat in forward direction: Sailor pushes water with oar in backward direction; resulting water pushing the oar in forward direction. Consequently, the boat is pushed in forward direction. Force applied by oar and water are of equal magnitude but in opposite directions.

Since man inherits y chromosome from his father and colour blindness is a x linked disease,man will be normal (xy). Woman is a normal carrier (XcX). Their male progeny will be diseased(XcY) And females will be carrier or normal.so chances are 50%
