(b) the cutoff wavelength
(c) the frequency corresponding to the cutoff wavelength
Two speakers, one directly behind the other, are each generating a 152-Hz sound wave. What is the least separation distance between the speakers that will produce destructive interference at a listener standing in front of them.
Write down the expression that shows the pressure
Calculate escape velocity for an object started at the surface of the earth, going straight up. Neglect any complications due to the earth turning.
A thin, flexible metal plate attached at one end to the platform, can be used to measure mass. When the free end of the plate is pulled down and released, it vibrates in simple harmonic motion with a period that depends on the mass attached to the pl..

A wrench 0.3 meters long lies along the positive y-axis, and grips a bolt at the origin. A force is applied in the direction of langle 0, 1, 2rangle at the end of the wrench. Find out the magnitude of the force in newtons needed to give 100 newton..
To fill a child's inflatable wading pool, you use a garden hose with a diameter of 2.90 cm. Water flows from this hose with a speed of 1.50 m/s. How long will it take to fill the pool to a depth of 25.0 cm if the pool is circular and has the diame..
Assume a small child rolls off a bed that is 0.38m above the floor. If the floor is hardwood, the child's head is brought to rest in approximately 2.2mm. If the floor is carpeted, this stopping distance is increased to about 1.1cm.
Consider two closely spaced and oppositely charged parallel metal plates. The plates are square with sides of length L and carry charges Q and -Q on their facing surfaces. What is the magnitude of the electric field in the region between the plate..
