Chapter 24 – Capacitance and Dielectrics

- Capacitance is a measurement of the ability of capacitor to store energy (V = U / q). Capacitors in Vacuum - Parallel Plate Capacitor: uniform electric field between the plates, charge uniformly distributed over opposite surfaces A Q E εo εo σ = = d A V Q C ab = =ε0 A Qd V E d o ab ε 1 = ⋅ = ε0 = 8.85 x 10-12 F/m

Combination of Waves

Interference of Waves When light waves travel different paths, and are then recombined, they interfere. Each wave has an electric field whose amplitude goes like: E(s,t) = E 0 sin(ks-ωt) î Here s measures the distance traveled along each wave’s path. Mirror 1 2 * + = Constructive interference results when light paths differ

Chapter 5 – Force and Motion I

Chapter 5 – Force and Motion I I. Newton’s first law: If no net force acts on a body, then the body’s velocity cannot change; the body cannot accelerate v = constant in magnitude and direction. - Principle of superposition: when two or more forces act on a body, the net force can be obtained by adding the individual forces vectorially.

Chapter 6 – Force and Motion II

A centripetal force accelerates a body by changing the direction of the body’s velocity without changing its speed. v, a = ctes, but direction changes during motion.-Centripetal force: a, F are directed toward the center of curvature of the particle’s path. 3 III. Non-Uniform circular motion

Gauss's Divergence Theorem - University of Utah

Flux = . because div E = 0. The field entering from the sphere of radius a is all leaving from sphere b, so To find flux: directly evaluate ⇀ sphere sphere q EX 4Define E(x,y,z) to be the electric field created by a point-charge, q located at the origin. E(x,y,z) = Find the outward flux of this field across a sphere of radius a
