Answer:
a. Mass number is the sum of number of protons and neutrons present in the nucleus of an atom.
A = p + n
Charge is a unit of matter that tells how more or less the number of electrons are present as compared to number of protons in an atom. A positive charge means the atom lacks electrons.
Gamma rays are highly energetic electromagnetic rays. They have high penetrating power and are very difficult to shield owing to high energy.
b. The compete nuclear equation is:
![^{210} _{89} Ac \rightarrow ^4 _2 He + ^{206} _{87}Fr](https://tex.z-dn.net/?f=%5E%7B210%7D%20_%7B89%7D%20Ac%20%5Crightarrow%20%5E4%20_2%20He%20%2B%20%5E%7B206%7D%20_%7B87%7DFr)
This is a alpha decay process because alpha particle which is Helium atom is being produced. Francium is being formed after alpha particle is emitted.
c. The complete nuclear reaction is:
![^{80} _{38} Sr \rightarrow ^0 _{+1}e + ^{80} _{37}Rb](https://tex.z-dn.net/?f=%5E%7B80%7D%20_%7B38%7D%20Sr%20%5Crightarrow%20%5E0%20_%7B%2B1%7De%20%2B%20%5E%7B80%7D%20_%7B37%7DRb)
This is a positron emission process where in Rubidium is being formed.
I'm not to sure what the question is but it sounds like you are describing the Law of Conservation of Energy: stating that energy can't be created nor destroyed, but instead transferred or conserved.

Answer: 0.09 m
Explanation:
Centripetal acceleration in terms of tangential speed is:
![a_c=\frac{v^2_t}{r}](https://tex.z-dn.net/?f=a_c%3D%5Cfrac%7Bv%5E2_t%7D%7Br%7D)
where r is the radius.
It is given that,
centripetal acceleration of the mouse, ![a_c=0.29 m/s^2](https://tex.z-dn.net/?f=a_c%3D0.29%20m%2Fs%5E2)
tangential speed , ![v_t=0.17m/s](https://tex.z-dn.net/?f=v_t%3D0.17m%2Fs)
Radius of salami is:
![r =\frac{(0.17m/s)^2}{0.29 m/s^2}=0.09m](https://tex.z-dn.net/?f=r%20%3D%5Cfrac%7B%280.17m%2Fs%29%5E2%7D%7B0.29%20m%2Fs%5E2%7D%3D0.09m)
Thus, the radius of the salami is 0.09 m.
The reason why it relates to the newtons 3 laws of motion because the first law of motion states that every object will stay at rest unless it's moved by an unbalanced force which is your hand. The second one states that <span> the velocity of an object changes when it is subjected to an external force meaning it's used by the equation that is commonly used for which is F=M*A. The way it relates to the second law because you are adding force some way or another, the mass is the egg and the acceleration is the drop of the egg while it free falls. And the last one, for a reaction there is always an equal or opposite reaction and the opposite reaction is the floor because it's going against the egg causing it to crack. If it was with the egg, it would have a soft, smooth landing.</span>
