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

- 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

The History of Solar - Energy

NASA launches the first Orbiting Astronomical Observatory, powered by a 1-kilowatt photovoltaic array, to provide astronomical data in the ultraviolet and X-ray wavelengths filtered out by the earth’s atmosphere. 1969 The Odeillo solar furnace, located in Odeillo, France was constructed. This featured an 8-story parabolic mirror. 1970s

motion, and a staggering new body of astronomical observations. The observations were made possible by the invention of the telescope in Holland c.1608 and by Galileo's ability to improve on this instrument without ever having seen the original. Thus equipped, he turned his telescope skyward, and saw some spectacular sights.

ON the EXPANSION of the UNIVERSE - NASA

galaxy is obtainable from astronomical measurements, but is not necessarily treated in terms of a higher dimensional geometry3. It is treated, rather, as an abstract numerical measure related to the distance – a type of metric – between P and P*. S and θ, in turn, are related by another “constant of proportionality,” ρ.

Writing Module: Paraphrasing

conventional astronomical techniques, we must rely on computer modules to guide our understanding. From: Lanzel, P.A. and Barnes, E.I. (2009). Global behavior of radial orbit instability. Journal of Undergraduate Research in Physics (Aug.): 1-13. Excerpt is from p.1. Maria’s paraphrase: There is a variety of evidence that shows dark

General Relativity

However, astronomical observations of double stars should reveal such fast and slow light, but in fact the speeds turn out to be the same. 3.Light is the propagation of an electromagnetic disturbance and electromagnetic elds are governed by Maxwell’s equations. However, these equations are not well-
