What are the three lowest frequencies for standing waves on a wire that is 14,0 m long, has a mass of 179 g, and is stretched under a tension of 750 N7

4) You are jogging along a road at a speed of 4.50 m/s. A car is driving towards you at a speed of 45.0 m/s and ishonking, You hear the car's honking at a frequency of 660.0 Hz. The speed of so und is 345 m/s. Draw a picture to help you visual the situation. Label it with important information, and state all of the given values in the question. [C 1]а. b. What is the name of this phenomenon, and why does it occur? [C 2] C.What is the frequency that the car is honking at? [A 4]

2) Light with a wavelength of 2000 Å is incident upon a metal that has a work function of 1.9eV. What is the maximum kinetic energy of the escaped electron?

Problem 39. Repeat Problem 38 if µ1 =0.5 kg/m and µ2=0.2kg/m.

Question 3, How does the amplitude with only one wave compare to that with two waves superposed with no phase difference? Support your observation using the concept of interference. g) Record your observations on how the wave pattern changes as you increase the phase difference to 180 degrees.

2. Produce one quick wave by yanking the wrench down and back up. Which way does the waveform point (up or down)?

A massless spring hangs from the ceiling with a small object attached to its lower end. The object is initially held at rest in a position y; such that the spring is at its rest length. The object is then released from y; and oscillates up and down, with its lowest position being 22 cm below y (a) What is the frequency of the oscillation? (b) What is the speed of the object when it is 19,0 cm below the initial position? (c) An object of mass 675 g is attached to the first object, after which the system oscillates with half the original frequency. What is the mass of the first object? (d) How far below y, is the new equilibrium (rest) position with both objects attached to the spring?

Organ pipe A, with both ends open, has a fundamental frequency of 400 Hz. The third harmonic of organ pipe B, with one end open, has the same frequency as the second harmonic of pipe A. Use 343 m/s for the speed of sound in air. (a) How long is pipe A? (b) How long is pipe B?

With what tension must a rope with length 3.00 m and mass 0.120 kg be stretched for transverse waves of frequency 40.0 Hz to have a wavelength of 0.890 m ?

Practical 1 - Laws of Motion Part A The aim of this practical is explore linear motion and the relationships between distance, displacement, velocity and acceleration.
