... The electrical resistivity of most materials changes with temperature. If the temperature T does not vary too much, a linear approximation is typically used: Metals In general, electrical resistivity of metals increases with temperature. Electron–phonon interactions can play a key role. At high temp ...

... Sound is an even less directly measurable variable. Typically a sensor of sound is a kind of pressure transducer called a hydrophone but its electrical output signal is manipulated further before storage since the sound is multivariable containing a time series of pressure fluctuations at a minimum. ...

SAT Subject Physics Formula Reference
... For more than one pair of charges, use this formula for each pair, then add all the UE ’s. The potential difference ∆V between two points is defined as the negative of the work done by the electric field per unit charge as charge q moves from one point to the other. Alternately, it is the change in ...

... A long vertical wire carries a steady 10 A current. A pair of rails are horizontal and are 0.20 m apart. A 20 ohm resistor connects points a and b, at the end of the rails. A bar is in contact with the rails, and is moved by an external force with a constant velocity of 0.40 m/s, as shown. The bar a ...
