Ch.6 Entropy, T, and Free Energy
Friction ; dissipative process ; erase order The 2nd law of thermodynamics Concept of free energy
Whenever we release an internal constraint on an isolated macroscopic system in equilibrium, eventually the system c
Ch.4 Random Walks, Friction, and Diffusion
Origin of friction: conversion of organized motion to disordered motion by collisions with surrounding, disordered medium Once we understand the origin of friction, a wide variety of other dissipative proc

Sinusoidal response of RC circuits
When both resistance and capacitance are in a series circuit, the phase angle between the applied voltage and total current is between 0 and p g 90, depending on the values of resistance and reactance.

Sinusoidal waveform Sine Si waves
The sinusoidal waveform (sine wave) is the fundamental alternating current (ac) and alternating voltage waveform waveform.
Electrical sine waves are named from the mathematical function with the same shape.

Magnetic fields are described by drawing flux lines that represent the magnetic field. Magnetic fields are composed of invisible lines of force that radiate

Good Morning, Ms. Park. This is Mary Tang from Dr. Han's office. I'm calling to give you the results of the test you had during your annual physical exam last Friday. Everything is normal, so you won't need to make a follow up
