Oxygen has Atomic number 8 so all isotopes have 8 protons and 8 electrons.

So the number of neutrons in Oxygen-18 = 18 - 8 = 10.

Option B is the correct one.

A neutral atom as the same number of protons and electrons.
ZanzabumX [31]

That is correct. Or so I believe. Either more or less than the other on the amount of protons and electrons, you can get either an unstable or a stable atom of an element.

A 0.70-kg basketball dropped on a hardwood floor rises back up to 65% of its original height. (a) If the basketball is dropped f
dem82 [27]

Answer:

Part a)

Loss = 3.6 J

Part b)

Loss = 0.99 J

Part C)

This is loss in terms of thermal energy due to collision with the floor

Explanation:

Part a)

Since we know that the ball rises up by 65% of initial height

so after first bounce it will lose 35% of its initial energy

so we will have

U = mgH

Energy Loss = 0.35 mgH[/tex]

Loss = 0.35(0.70)(9.81)(1.5)

Loss = 3.6 J

Part b)

Energy of the ball after first bounce

U_1 = 0.65 mgH

energy of ball after 2nd Bounce

U_2 = 0.65(0.65 mgH)

energy of the ball after 3rd bounce

U_3 = (0.65)(0.65^2)mgH

U_3 = 0.65^3(0.70)(9.81)(1.5)

U_3 = 2.83 J

Now we will have energy loss in fourth bounce given as

Loss = 0.35 U_3

Loss = 0.35(2.83)

Loss = 0.99 J

Part C)

This is loss in terms of thermal energy due to collision with the floor
