How does gravity depend on the mass of the two objects?
O
A. Gravity increases as the mass of either object increases
O
B. Gravity decreases as the mass of the smaller object increases
O
C. Gravity decreases as the mass of the larger object increases.
O
D. Gravity increases with the product of the mass and the distance,
SUBMIT

A

Explanation:

Because the gravity and the mass of objects are proportionate

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.
