Answer:
the ratio of protons to neutrons
Explanation:
Nuclear stability is based on the ratio of protons to neutrons. The nuclear space is made up of protons and neutrons that occupies the nucleus of an atom.
For every atomic nucleus, there is a specific neutron/proton ratio which ensures the stability of the nucleus.
For sodium, Na, the neutron/proton ratio for stability is 12/11.
Any nucleus with a neutron/proton combination different from its stability ratio will be unstable.

Answer:
= 1/5 L
Explanation:
To find the center of mass of the system let's use
∑ r_i x_i
where m is the total mass of the system
let's apply this expression to our case
Let's set the reference frame on the star
r_{cm} = L
= 1/5 L
Hey, the breast center is 1/5 of the distance between the star and the planet.
Answer:
I can not see the image, so i will answer in a general way.
As you know, the sound behaves like a wave, this means that the sound needs some time to cover a given distance. An example of this motion can be seen when you drop a little stone in water, and you can see how the waves expand.
This means that the one who will hear the sound first, will be always the one that is closer to the source of the sound, in this case, the sound comes from the ball hitting the backboard, then the one who is closer to the backboard will hear the sound first.
