<span>The career that is most concerned with the study of radioactive isotopes is chemistry. You need to have passed AP chemistry to actually deal with the isotopes. In a quick reference, isotopes are when the atom has difference amount of neutrons, making the atomic mass differ.</span>

The Correct answer to number 1 is A or D

The correct answer to number 2 is C because transmission meaning is to travel.

You accidentally slide a glass of milk off a table that is 0.9 m tall. How long does it take the milk to hit the ground.

Fine, lets do a retry of this.

Δd = -0.9m

v₁ = 0

v₂ = ?

a = -9.8 m/s²

Δt = ?

We can use the following kinematic equation and solve for Δt.

Δd = v₁Δt + 0.5(a)(Δt)²

Δd = 0.5(a)(Δt)²

2Δd = a(Δt)²

√2Δd/a = Δt

√2(-0.9m)/(-9.8 m/s²) = Δt

0.<u>4</u>28571428574048 = Δt

Therefore, it takes 0.4 seconds for the glass to hit the ground, or 0.43s as you said (even though I don't believe it follows significant digit rules)
