What is the minimum energy required to launch a satellite of mass m from the surface of a planet of mass M and radius R in a circular orbit at an altitude of 2R? Total energy E=1/2mv^(2)-(GmM)/r =(GmM)/(2r)-(GMm)/r=-G(mM)/(2r) r=2R=R=3R E=(GmM)/(6R) Potential energy =-(GMm)/R Minimum energy required =1/6(GMm)/R-((-GMm)/R)=5/6(GMm)/R

The electron’s speed is largest in the first Bohr orbit, for n = 1, which is the orbit closest to the nucleus. The radius of the first Bohr orbit is called the Bohr radius of hydrogen, denoted as a0. Its value is obtained by setting n = 1 in Equation 3.5.6: a0 = 4πϵ0 ℏ2 mee2 = 5.29 × 10 − 11m = 0.529 Å.

Radius of gyration representation(SRC: Civilsnapshot). Firstly, we calculate the radius of gyration for cross-sections of 3D bodies or features. For each cross-section of bodies, the radius of gyration is also changed. The radius of gyration is generally used for buckling calculations of columns. The formula of the radius of gyration; r is the.

Solution Consider a rigid object rotating with a constant angular speed ω about an axis perpendicular to the plane of the paper. A body of N particles For theoretical simplification, let us consider the object to be consisting of N particles of masses m 1, m 2, …..m N at respective perpendicular distances r 1, r 2, …..r N from the axis of rotation.

Historically, Bohr’s model of the hydrogen atom is the very first model of atomic structure that correctly explained the radiation spectra of atomic hydrogen.
