Chapter 29 – Electromagnetic Induction

Faraday’s Law of Induction: - The induced emf in a closed loop equals the negative of the time rate of change of the magnetic flux through the loop. dt ε= − dΦB - Increasing flux ε< 0 ; Decreasing flux ε> 0 - Direction: curl fingers of right hand around A, if ε> 0 is in same direction of fingers (counter-clockwise), if ε< 0

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

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

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
