If they are traveling at the same speed, which will have the most kinetic energy? A. A 5-kilogram ball

B. A 25-kilogram ball

C. A 10-kilogram ball

D. A 1-kilogram ball

B. (A 25 kg ball)

Explanation:

Since , and velocity is the same for all four balls, the ball with the greatest mass will have the greatest kinetic energy (since mass and KE are directly related). Below shows these calculations:

A. m = 5

B. m = 25

C. m = 10

D. m = 1

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
