A long, flexible, and very light strip of metal, such as a saw blade, is clamped to the edge of a table, extending horizontally over the edge like a miniature diving board. When a gob of putty is placed on the end, the strip sags and comes to a new equilibrium position with its tip a distance 1.0 cm below its original position. If the end of the strip is then ligltly tapped, its tip will oscillate in simple harmonic morion. With what frequency should the tip be tapped to make the strip oscillate with maximum amplitude?
Find out the potential difference between a point.
A 1025 kg car carrying four 78kg people travels over a rough "washboard" dirt road with corrugations 4m apart which causes the car to bounce on its spring suspension.
A person with perfect pitch sits on a bus bench listening to the 441-Hz horn of an approaching car. If the person detects a frequency of 479 -Hz, how fast is the car moving.
Some athletes can put out as much as 800 watts in short bursts. If you could sustain such energy output long enough to reach the top of a mountain, how much time would it take you to get there from the valley, 3000 meters below the peak? So how does ..
An AC power generator produces 46 A (rms) at 3600 V. The voltage is stepped up to 100000 V by an ideal transformer, and the energy is transmitted through a long-distance power line that has a resistance of 100 . What propotion of the power deliver..
