Which is not classified as a particulate? a. ozone b. lead c. ash d. dust

Ozone is not classified as particulate.

A particulate is a very small solid particle that can exist in suspension in both liquid and a gas. This  particle remains suspended because it does not dissolve in the liquid or gas that it is suspended in. Dust and ash are capable of being particulates in both gases and liquids. Lead has been known to be a particulate in water, acting as a contaminant.

On the other hand, ozone is a gas that exists as a molecule of three oxygen atoms bonded together. For this reason, Ozone can not be particulate. The correct answer is A.Ozone.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
