Your list of choices is a very short list, and doesn't include any

correct explanation.

The mass of an atom is roughly the number of protons AND neutrons

in its nucleus, but the element only depends on how many protons are there.

Different atoms of the same element may have different numbers of

neutrons, so their masses are different. But they're the same element,

because they all have the same number of protons.

+14-17+16-28 = -17+16-14 = -1-14=-15 ... west, and out of breath

First we need to find the time in the air

d = 1/2gt^2 + vt

Since there is no inital vertical velocity

4.1 = 1/2 (9.8) t^2

8.2/9.8 = t^2

0.8367 = t^2

t = 0.9147s

Now we multiply by speed

7m/s x 0.9147s = 6.4m

Answer: **Growth or Cell Growth.**

Cell growth is the increase in cytoplasmic volume. It is the increase in the number of cells that is being produced in your body. Cells undergo a process called mitosis.

Mitosis is the process when a single cell divides into two identical cells that have the same number of chromosomes and genetic content as the original cell that it came from.

Normal Force = 54 N

acceleration = 1.2 m/s^2

For Normal Force:

According to the force diagram, we can come up with the equation (all up and down forces):

10 sin 30 + Normal Force - 58.8 = 0

Normal Force = 53.8 N = 54 N

For acceleration:

According to the force diagram, we can come up with the equation (all left and right forces):

10 cos 30 - 1.5 = (6.0) (Acceleration)

Acceleration = 1.19 m/s^2 = 1.2 m/s^2
