I messed up earlier, sorry, it's kinda lucky I saw a photo that said 1 billion seconds is 31 years XD

carbon-12 and carbon-14 are differed by the neutrons count in their atoms.
<u>Explanation:</u>
The two isotopes of the carbon element are carbon-12 and 14 . The difference between them is the neutrons count in each of their atoms. This is how it works. The digit after the atom's name represents the protons and neutrons count in the atom or ion. The atoms of both carbon isotopes have 6 protons. carbon-12 atoms comprise with 6 neutrons, whereas 8 neutrons in carbon-14.
A neutral atom usually have the same counts of electron and proton, so that a neutral carbon-12 or 14 atom have 6 electrons. Although neutrons do not possess any electric charge, their mass is similar to that of protons, so different isotopes consist different atomic masses. Carbon-12 seems to be more lighter when compared with carbon-14.

Answer:
![a=2g](https://tex.z-dn.net/?f=a%3D2g)
Explanation:
Let the radius of the hemisphere is R. The mass is released from rest so the initial speed is equal to zero and acceleration is equal to the g.
By the Newton's 3rd equation,
Now, at the bottom hemisphere the centripetal acceleration will act on the mass and the direction of this force is towards center,
![a_c=\frac{v^2}{R}\\a_c=\frac{(\sqrt{2gR} )^2}{R}\\a_c=2g](https://tex.z-dn.net/?f=a_c%3D%5Cfrac%7Bv%5E2%7D%7BR%7D%5C%5Ca_c%3D%5Cfrac%7B%28%5Csqrt%7B2gR%7D%20%29%5E2%7D%7BR%7D%5C%5Ca_c%3D2g)
Hence, the acceleration on the bottom of the hemisphere is equal to the 2g.
