Why, in terms of work and energy, did you have to push on the pendulum string as it was moving away from you in order to maintain a large amplitude? How would you explain the difference between kinetic energy and potential energy? Give an example from the real ...
If E=mc^2, how does it relate to Ek+1/2mv^2? How does it work when v=c? Describe how an electroscope works. Explain briefly how the photoelectric effect is used in the operation of the soundtrack of a motion picture. What is the device that you use that uses the most sophisticate...
When the beam is "painting," it is on, and when it is flying back, it is off so that it does not leave a trail on the screen. The term horizontal retrace is used to refer to the beam moving back to the left at the end of each line, while the term vertical retrace refers to ...
The reference cell's resistance is determined by AC-coupling a square wave of known amplitude and frequency via a series resistance, and measuring the resultant AC waveform's amplitude. This waveform is always present, and since it is at a high frequency with respect to the response of the ...

at constant voltage and at constant current, are possible. A combination of both has been suggested by a manufacturer [91] wherein the applied AC current is adapted during an experiment to keep the amplitude of the registered AC response of the cell at a roughly constant value when changing ...
The two main components of the electrical input are the drive frequency and voltage amplitude. The frequency determines how fast the piezo will vibrate or change state. Both periodic (regularly repeating) and arbitrary signals can be used to drive a piezo, which corresponds to either continuous (...
If nothing else can remove an unwanted note in the middle of a mixed sample, try muting it with Melodyne Editor's Amplitude Tool — there's no guaranteeing it'll work, given that the plug-in wasn't officially designed for use on complex mixes of different instruments, but it can nonethel...
How does an electric motor work, linking to the theory of electromagnetism? How do electric and magnetic forces relate to one another? How are force and work conceptually linked? How are they linked mathematically? In an input of 100 J in a pulley system increases the potential energy ...
If a sound intensity level of 0 dB at 1000 Hz corresponds to a maximum gauge pressure (sound amplitude) of 10^-9 atm, what is the maximum gauge pressure in a 120-dB sound? How does blood flow through the heart? What is the path it takes?
