g A ball is thrown against the wall and bounces back with the same velocity. What type of collision is this

Physics

Answer:

Perfectly elastic collision

Explanation:

In a closed system, an elastic collision is a type of collision between two bodies, where the total momentum and kinetic energy are conserved.

We are told from the problem that the ball bounces back with its original velocity. For the ball to bounce back to the thrower in the first place, this is our first hint that the collision is elastic. If the collision was inelastic, the ball would most likely have stuck to the wall.

In addition to that, the velocity of the ball remains fairly unchanged even after the collision. This confirms that the kinetic energy it had before the collision is the same as the kinetic energy it has after the collision.  

As a result of this, the collision is perfectly elastic

pickupchik [31]

Answer:

The purpose of step 1 is to induce magnetism into the needle, so that it retains magnetism and behaves as a magnet after the process.

Explanation:

The method of production the needle magnet in the procedure is the single stroke. This process involves a continuous stroking of a magnetic object (e.g needle) repeatedly for a period or number of times with a permanent magnet. Thus, when the permanent magnet is removed, the object retains magnetism, and behaves like a magnet.

The importance of the stroking process is the turn a magnetic object to a magnet by inducing magnetism into it.
