When responding to sound, the human eardrum vibrates about its equilibrium position. Suppose an eardrum is vibrating with an amplitude of 5.75 10-7 m and a maximum speed of 3.06 10-3 m/s.
A) what is the frequency (in Hz) of the eardrums vibration?
B) what is the maximum acceleration of teh eardrum?
One of Einstein's postulates says that nothing travels faster than the speed of light in a vacuum, c, what limit does this place on the numerical value for n
Two loudspeakers are vibrating in phase. They are set up as point C is located. Assume the speed of sound is 342 m/s. The speakers play the same tone. What is the smallest frequency that would produce destructive interference at point C.
A pendulum is 1.20 metres long. What is the speed of the bob when it passes by its equalibrium position if it is pulled aside until it makes an angle of 25 degrees to vertical.
Two charged dust particles exert a force of 4.30×10-2 N on each other. What would be the force if they are moved so they are only one-sixth as far apart.
If the electric field strength in air exceeds 3.0 multiplied by 106 N/C, the air becomes a conductor. Using this fact, determine the maximum amount of charge that can be carried by a metal sphere 3.1 m in radius.
An elevator cable can withstand a maximum tension of 19,500N before breaking. The elevator has a mass of 480 kg and a maximum acceleration of 2.24 m/s2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaki..
