A student on a piano stool rotates freely with an angular speed of 2.91 rev/s. The student holds a 1.45-kg mass in each outstretched arm, 0.791 m from the axis of rotation. The combined moment of inertia of the student a ...
Starting with the Einstein relationship, derive the Boltzmann relationship for the equilibrium electron concentration, N(x)-N(x 1 )exp{q[V(x)-V(x 1 ))/kT]. Is this result consistent with the fact negatively charged elect ...
1. Show that this modified Lempel-Ziv code is still not ‘complete', that is, there are binary strings that are not encodings of any string. 2. Give examples of simple sources that have low entropy but would not be compre ...
Question from: Nanotechnology: Understanding Small Systems The random motion of molecules within a cell is driven by energy from heat. a. At what temperature do most cells prefer to live? b. The calorie is a unit of ener ...
Erik's puzzle. In a stripped-down version of Conway's game of life, cells are arranged on a square grid. Each cell is either alive or dead. Live cells do not die. Dead cells become alive if two or more of their immediate ...
1. Drive the mobility formulae and its temperature dependence for a neutral scatterer whose scattering cross section is πa t 2 and constant. 2. Sketch the transverse acoustical lattice vibration wave at t=0 and a later ...
Graph the functions described in parts (a)-(d). (a) First and second derivatives everywhere positive. (b) Second derivative everywhere negative; first derivative everywhere positive. (c) Second derivative everywhere posi ...
Imagine fitting a mixture of ten Gaussians to data in a twenty-dimensional space. Estimate the computational cost of implementing inferences for this model by enumeration of a grid of parameter values.
Question: Ultrasound can be used to deliver energy to tissues for therapy. It can penetrate tissue to a depth approximately 200 times its wavelength. What is the approximate depth of penetration of ultrasound at a freque ...
