FIGURE P23.43 shows a thin rod of length L with total charge Q. a. Find an expression for the electric field strength at point P on the axis of the rod at distance r from the center. b. Verify that your expression has the expected behavior if r W L. c. Evaluate E at r = 3.0 cm if L = 5.0 cm and Q = 3.0 nC.
Physics 2080 Week 1: Chapter 16 – Temperature Convection, Conduction, and Radiation -Convection: heat transfer through objects that are touching (solids) -Conduction: heat transfer through fluids that rise when heated creating convection currents (hot fluid rises, cooler fluid sinks) -Radiation: how heat moves through places where there are no molecules (sunlight radiates heat) Ice Water Gas (Steam) -cold -more flexible particles -particles moving a lot -packed particles -warmer -hot -more space for molecules to move -By heating, the molecules of a substance move faster, high kinetic energy, and therefore, increased temper
