Describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? )

A root beer float is a combination of root beer, ice cream and foam.

The three states are:

a) Root beer is a liquid wherein the particles move freely and tend to take the shape of the container.

b) Ice cream is a solid in which the particles have a fixed shape and held strongly in place. Unlike liquids, solids retain their shape.

c) Foam is a gas which is produced by the reaction of root beer with the ice cream. Gas particles move quickly and fill the container they occupy.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
