This is a problem for school that I need a little help with: Draw a circuit diagram that includes an electric motor, a green light, a red light, and a switch. If the motor is on, the red light should be on. If the motor is off, the green light should be on. Here is what I have so far. I'm...

Wavelength - Disatance from crest to an adjacent crest or trough to an adjacent trough. (They will be the same length) For complete destructive interference the wavelengths and amplitudes must be the same and the troughs of one wave must line up with the the crests of the other (and vice versa).

I have to find the vertical displacement of a potato shot out of a potato launcher (Gr. 11 Physics assignment). It would make sense (and make this easier) to assume that the potato went straight up and down and I am allowed to assume that air resistance is negligible. My main problem is proving...
