Linear Superposition

The sound produced by a loudspeaker has a frequency of 12,000 Hz and arrives at the microphone via two different paths. The sound travels through the left tube LXM, which has a fixed length. Simultaneously, the sound travels through the right tube LYM, the length of which can be changed by moving the sliding section. At M, th ...continues

Sound waves : Calculating the distances between the points of interference.

Speakers A and B are vibrating in phase. They are directly facing each other, are 7.80 m apart, and are each playing a 73.0 Hz tone. The speed of sound is 343 m/s. On the line between the speakers there are three pointswhere constructive interference occurs. What are the distances of these three points from speaker A?

Calculating the frequency of a string.

When a guitar string is sounded along with a 440 Hz tuning fork, a beat frequency of 5Hz is heard. When the same string is sounded along with a 436 Hz tuning fork, the beat frequency is 9 Hz. What is the frequency of the string?

oscillation

the oscillation period is 1.25 seconds (just in case it's hard to read)

capacitance

1. What is capacitance? 2. How does a given capacitor's value of capacitance depend on an external potential difference of a connected source? 3. How should you connect four identical capacitors to result in an equivalent capacitance that is equal to one individual capcitance?

Physics question

1. A simple harmonic oscillator has a total energy of E. a.) Determine the kinetic and potential energies when the displacement is one half the amplitude. B.)For what value of the displacement does the kinetic energy equal the potential energy? 2.A 5.00g bullet moving with an initial speed of 400m/s is fired into and passes ...continues

Calculating the force required to lift a larger piston.

The areas of the pistons in a hydraulic lift are 4000cm^2 and 8cm^2 respectively. What force on the smaller piston is required to lift a 20,000 N car by the larger piston?

Fluids

What is the ABSOLUTE pressure on the bottom of Archimede's bathtub if the dimensions of the tub are 3m long by 1.2m wide by 0.8m high? Assume that the tub is filled to the top with water and Archimedes hasn't gotten into the tub yet? What is the force on the bottom of Archimedes's baththub?
