The two decayed particles will form identical spirals but in the opposite direction to one another, as they will have to be oppositely charged to preserve the overall charge. The spiral patterns will be i...

This depends on what "best" means, but generally this boils down to location.

As an example, consider geothermal energy. This is derived from heat sources inside the Earth. Some places, s...

It is best to consider this in slow motion. First we have a wall which is at equilibrium (no external forces/all forces are balanced). Someone decides that the wall is in its way and wants to break down t...

Young's Modulus is defined as the ratio of stress to strain. E = stress/strain. Stress is the force per unit area, F/A. By substitution, we can see that E = F/(A x strain). Rearranging gives F = E x A x s...

The nucleus is made up of protons and nuetrons, which means there is an electric repulsion. The nucleus is held together by somethign called the strong nuclear force. This overrides the electromagnetic re...
