S. In the space below, describe how you might design a circuit to yield 20mA of current through the LED You may wish to draw out the circuit, but you should explain in words your thought process for your design (You can hand-draw the circuit, scan in the drawing and insert it below, or go online to: www.circuitlab.com editor and draw the circu t, then cutpaste a screen capture of the design)

Draw the structure of the alkyl bromide from which the alkyl acetate shown below was made by Sn2 reaction. ball & stick - + labels • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • If a group is achiral, do not use wedged or hashed bonds on it. • In cases where there is more than one answer, just draw one. • Use “flat” representations of rings, not chairs, in your drawing.
As shown in the figure below, a stick of length = 0.430 m and mass m 0.245 kg is in contact with a rough floor at one end and a frictionless bowling ball (diameter d 19.00 cm) at some other point such that the angle between the stick and the floor is 0 - 30°. Determine the following 30.0 (3) magnitude of the force exerted on the stick by the bowling ball 3.96 X Since the stick is in static...
