<span>he easiest way to see parallax is to hold out your finger vertically in front of a background object, a door or wall for example. Shut your right eye and note where on the background object the image of your finger appears. Now open your right eye and close the left one without moving your finger. The image of your finger should appear to have jumped to a different spot on the background wall. It is possible to tell how far away your finger is from your eyes just by measuring the distance between your eyes and the distance that the image appeared to move in degrees of arc. </span>
The potential energy of the ball is 8 J.
<h3>What is mechanical energy?</h3>
Mechanical energy is given as the energy possessed by an object to do work. It is given as the sum of the kinetic energy and potential energy.
Mechanical energy = Kinetic energy + Potential energy
The given ball has:
- Mechanical energy = 25 J
- Kinetic energy = 17 J
The potential energy is given as;
25 J = 17 J + Potential energy
Potential energy = 25 J - 17 J
Potential energy = 8 J
The potential energy of the ball is 8 J.

Answer:
If you add the masses of all the products after fission, they are LESS than the mass of the reactants.
Explanation:
A nuclear fission reaction is a radioactive reaction which in which a heavy nucleus spontaneously disintegrates into 2 lighter nuclei and some neutrons with a release of large amount of energy.
When nuclear fission occurs, a mass deficit between the decaying nuclei and the product occurs. It is this mass that actually yields the energy that is produced as a by product of the reaction.
A mixture is made from different substances that are not chemically joined. For example, powdered iron and powdered sulfur mixed together makes a mixture of iron and sulfur.
