Answer:
The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.

The statement that best describes nuclear fusion is;
Nuclei combine to form a heavier nucleus, releasing energy
Explanation:
In nuclear fusion, we have the reaction of the nuclei of two or more atoms coming together (combining) to form heavier elements and subatomic particles such as protons and neutrons accompanied by the release or absorption in energy depending on the difference between the mass of the reactants and the products
Some nuclear fusion reaction require an input of energy and such reactions are therefore not spontaneous
The best option is nuclei (two or more nuclei) combine to form a heavier nucleus, releasing energy.

Answer:
G M m / R^2 = m v^2 / R centripetal force equals gravitational force
1/2 m v^2 = G M m / R = KE rearranging the above equation
T = 2 pi R / v time for one revolution (period)
T^2 = 4 pi^2 R^2 / v^2
From the very first equation v^2 = G M / R
so T^2 = 4 pi^2 R^3 / (G * M)
