For example, if v2 is greater than v1 in the equation, then P2 must be less than P1 for the equality to hold. Example 1. Calculating Pressure: Pressure Drops as a Fluid Speeds Up In Example 1 from Flow Rate and Its Relation to Velocity, we found that the speed of water in a hose...

In addition, our model for a two-level system cannot fully capture the whole physics of a semiconductor amplifier, in particular by neglecting the linewidth enhancement factor (Henry’s α factor) of semiconductors, and this could have an impact on some important features of the pulses. Another ...

This is an evolution equation for the probability density of a particle of a rarefied gas and its scope is to describe the thermodynamic behavior of a suitable class of macroscopic systems possibly not in thermal equilibrium. Here we want to illustrate the delicate passage from the Hamiltonian ...
However, for those interested, a derivation by Dyson (1990), attributed to Feynman, is available in the literature. Maxwell equations in the rationalized metric system are given by (5.1)∇·B=0 (5.2)∇·E=ρ/ε0 (5.3)c2∇×B=∂E/∂t+j/ε0 (5.4)∇×E=−∂B/∂t (...

The sound speed decreases from the surface down to h = 1200 m and then increases from h = 1200 m to the bottom of the ocean (h = 4800 m). Figures which present the ray pattern for horizontal distances up to 150 km and for frequencies between 25 and 200 Hz clearly point out the ...
Values of ε for several cubic semiconductors, such as Si, Ge, and GaAs, are shown in Tables 1 and 2. Typically, two values of ε(ω) are given for each semiconductor. The low-frequency value ε0 represents the value of the dielectric function for frequencies below the optical phonon ...
(General Physics)physicsa partial differential equation describing wave motion. It has the form ∇2φ = (1/c2) × (∂2φ/∂t2), where ∇2is the Laplace operator,tthe time,cthe speed of propagation, and φ is a function characterizing the displacement of the wave ...
