integers such that n1 > n2‚ and RH is the Rydberg constant for hydrogen. No one understood why these formulas worked until Neils Bohr created the first quantum model for the binding energy of the electrons in a hydrogen atom.: where k = 8.988 x 109 Nm2/C2‚ and aB is the Bohr radius. The observed light is produced by photon emission when an electron changes energy levels. This change in energy can be shown as: where h = 6.626 x 10-37 m2kg/s.

overcrowded. The Supreme Court decided on May 23‚ 2011 that the overcrowding of the California prisons was a violation of the Eighth Amendment rights (Brown‚ Governor of California‚ et al. v. Plata et al.) This decision pushed for the Assembly Bill AB 109 which helped to stop prisoners from going in and out of the state prison system. “ It is the cornerstone of California’s solution for reducing the number of inmates in the state’s 33 prison to 137.5 percent of design capacity by June 27‚ 2013‚ as

Continuity Equations Continuity equation is a equation that explain the transport of a conserved quantity. Since‚ mass‚ energy‚ momentum are conserved under respective condition‚ a variety of physical phenomena may be describe using continuity equations. By using first law of thermodynamics‚ energy cannot be created or destroyed. It can only transfer by continuous flow. Total continuity equation (TCE)‚ component continuity equation(CCE) and energy equation(EE) is applied to do mathematical model

Question 1.1: What is the force between two small charged spheres having charges of 2 × 10−7 C and 3 × 10−7 C placed 30 cm apart in air? Answer Repulsive force of magnitude 6 × 10−3 N Charge on the first sphere‚ q1 = 2 × 10−7 C Charge on the second sphere‚ q2 = 3 × 10−7 C econd Distance between the spheres‚ r = 30 cm = 0.3 m Electrostatic force between the spheres is given by the relation‚ Where‚ ∈0 = Permittivity of free space Hence‚ force between the two small charged spheres is 6 × 10−3 N.
