A full-wave bridge-rectifier circuit with a 1 k-ohms load operates from a  Household supply through a 12-to-1 step-down transformer having a single secondary winding. It uses four diodes, each of which can be modelled to have a 0.7-V drop for any current. What is the peak value of the rectified voltage across the load? 

(a) What is the magnitude of an electron’s acceleration in a uniform electric field of magnitude  ? (b) How long would the electron take, starting from rest, to attain one-tenth the speed of light? (c) How far would it travel in that time?

Choose a color that you feel drawn to. You can find this color online or in a book or magazine. Then use the language you learned in this unit to describe this color and explain why it appeals to you. For example, you might describe its hue, saturation, or place on the color wheel. Or you might explain how others are likely to react to it based on the psychology of color.
