For every action there is an equal and opposite reaction. true or false

True

Explanation:

This is the main principle contained in Newton's third law, which states:

"When an object A exerts a force on an object B (action), then object B exerts an equal and opposite force on object A, called reaction"

The law states that the two forces are equal in magnitude, and opposite in direction. It is also important to notice that the two forces do act on different objects, not on the same object, this is why they never appear both in the same free-body diagram of an object.

An example of action-reaction pair is the force exerted by a bat on the baseball (action) and the force exerted by the baseball back on the bat (reaction).

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
