Describe the composition of the nucleus of an atom.

Explanation:

The nucleus of an atom is made up of protons and neutrons. This was discovered in 1911 by Ernest Rutherford based on the gold foil experiment.

These baryons are further made up of sub-atomic fundamental particles known as quarks joined by the strong interaction.

Nuclei are bound together by the residual strong force (nuclear force). This force or baryon is much weaker between neutrons and protons because it is mostly neutralized within them, in the same way that electromagnetic forces between neutral atoms (such as van der Waals forces that act between two inert gas atoms) are much weaker than the electromagnetic forces that hold the parts of the atoms together internally.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
