Questions Chris has answered

Explain the Principle of Moments.

The moment of a force about any point is defined as the force x perpendicular distance from the line of action of the force to the point - moment = F x d the unit is Nm.

Principle of moments states that for a body in equilibrium the sum of clockwise moments = sum of anticlockwise moments about any point.

F1d1 = F2d2 or W1d1 = W2d2, where W is weight

Explain the process of annihilation?

Matter and antimatter will annihilate if they meet:
1) Particle meets antiparticle.
2) Both have rest energies due to their masses.
3) Both have kinetic energies due to their movement (if they are moving).
4) They annihilate to produce 2 photons which move in opposite directions.
5) Each photon energy = ½ the total (rest energy + kinetic energy).

What do the logical operators AND, OR, XOR and NOT do?

AND (both conditions on either side of the AND operation MUST be satisfied for the IF function to work)

OR (either condition on each side of the OR operation MUST be satisfied for the IF function to work)

NOT (used when something needs to be displayed UNLESS a value is a certain amount/type/name etc.)

XOR (used when exclusively ONE of the conditions has to be met – not both! This is where XOR and OR differ.)
