What will happen to the 5 pesos stack coins when you hit the coin at the bottom?why is this so?

The correct answer is "The 5 pesos stack coins will remain at its place".

Explanation:

According to Newton's first law "every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force". In this case, hitting a single 5 pesos coin at the bottom of the stack does not represent an external force with enough energy to move the stack considerably. Therefore, the 5 pesos stack coins will remain at its place since it tends to remain at rest as any other object.

the answer is minerals.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
