What is the formula for Critical Velocity of Satellite Orbiting at a height from the Earth’s Surface?

Critical velocity is the minimum velocity of projection for which satellite revolves in a circular orbit around the earth.

What is the formula for acceleration due to gravity at height h from the earth’s surface?

Let us consider mass of the earth as M, radius of earth as R, and the body is at an altitude h from the surface of the earth at distance r, gh is gravity at height h from the earth’s surface. The acceleration gained by an object because of gravitational force is called its acceleration due to gravity.

What is the formula of density of a nucleus?

Density is defined as its mass divided by its volume. In the same way density of nucleus is defined as the ratio of mass of nucleus to its spherical volume. The mass of nucleus is equal to number of nucleons in nucleus (A) and the mass of single nucleon (m). Since mass of neutron and proton are same. M = A m. Nucleus is spherical in shape with radius r. So volume of nucleus (V) = 4/3(Π r3).

What is the formula of radius of a nucleus?

Experiments that studies the size of nuclei indicate that the volume of nuclei is directly proportional to the total number of nucleons present.

What is the value of Atomic mass unit (a.m.u.)?

Atomic mass unit is taken to be the 1/12th of the actual mass of carbon isotope 6C12 The value of Atomic mass unit (a.m.u.) is given as, 1 a.m.u. = 1.66 × 10-27 kg 1 a.m.u. = 931 × 106 eV 1 a.m.u.
