Name the three different types of radiation and describe how they are different in their penetrating abilities. Explain.

The three different type of radiations are:

1) Alpha (α) radiation

2) Beta (β) radiation

3) Gamma () radiation

Penetrating Ability:

Penetrating Ability of gamma rays is the highest.

That of Beta Rays is higher.

That of Alpha Rays is lowest

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
