A Is a standard amount like a kilometer or gallon when used to communicate different quantities
Tatiana [17]
I think the missing word you're looking for here is 'unit'. The examples such as kilogram and gallons are all units of measurement. These are standard amounts used for mass, volume, and length. It is especially important to be consistent with this units especially when doing dimensional analysis.

In three to four sentences, explain how the photoelectric effect supports a particle model of electromagnetic radiation. As part
mr_godi [17]

The photoelectric effect supports a particle model of electromagnetic radiation as it behaves like an elastic collision between two particles.

<h3>What is Photoelectric effect?</h3>

This is defined as the emission of electrons when electromagnetic radiation, such as light, hits a material.

The energy of a wave increases with an increase in intensity and in photoelectric effect. However intensity has no effect on the energy of electrons emitted which is why it is inadequate to explain the photoelectric effect.
