Cranberry Juice is a Homogeneous Solution.

Explanation:

A Homogeneous solution is identifiable as a solution that looks like it is one single fluid.

A heterogeneous solution would be categorized as a solution that is obviously two different compounds, like oil and water.

A colloid is similar to the way a homogeneous solution is identified, however, colloids have particles suspended in them that are 1 nanometer to 1 micrometer in length (If particles are smaller than 1 nanometer it is considered a homogeneous solution). Colloids can be identified by shining a flashlight into them. If the beam disperses, it's a colloid. If it goes straight through without dispersing, it's a homogeneous solution. A colloid example is Milk.

A Suspension is similar to a colloid, however, the particles in a suspension are larger than 1 micrometer. Particles in a suspension can often be seen with the naked eye, whereas Colloid particles cannot. A suspension's particles will often separate from the base solution in time. A suspension example would be shaking glitter up in a bottle of water.

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.
