Question

Which of the following have “quantized” values?

The length of a blade of grass.

The number of jelly beans in a bowl.

The number of eggs in your refrigerator.

The volume of milk in a glass.

The diameter of a tree.

The number of bricks in a wall.

please give a reason as well so I can undertand why

Answer 1

The length of a blade of grass not quantized

The number of jelly beans in a bowl. --> quantized (integer)

The number of eggs in your refrigerator. --> quantized (integer)

The volume of milk in a glass --> continuous number, not quantized

The diameter of a tree. --> continuous number, not quantized

The number of bricks in a wall. --> quantized (integer)

In general... if those are integers, and not continuous number, i.e. it is discrete number... then it is a quantized number

this is probably aiming to show you why energy is quantized, i.e. in packages, since the least amount of unit (quanta) is packed in units of discrete energy
