State the law of conservation of energy. According to this law, how is the total amount of energy affected in any process (like a swinging pendullum or bowling ball hitting the pins)?

The law of conservation of energy is that energy can not be created or destroyed. This means that it can only be transferred from one form of energy to another. In any situation the total amount of energy is, let's say for example a ball rolling down a hill, both the potential and kinetic energy is combined to find the total energy. The total amount will be the same in a process because the amount of potential energy or kinetic energy can only transfer to what is already being used. Example, say the total energy will be on a pie chart, let's say 1/4 of the graph is potential and 3/4 is kinetic. No matter what, the pie graph will be 4/4.

Answer : Its width can be measured

Explanation:

The width of a plane can be measured is not a characteristic of plane.

The properties of a plane include:

A plane does not have any thickness hence its width cannot be measured. A plane goes on forever i.e it is infinite. A plane is two dimensional and is an imaginary line. A plane cannot be seenTwo planes can either be parallel or they can have a line of intersection. If two planes are perpendicular to a line, then they must be parallel.
