Two traveling waves with the same amplitude A, frequency f, and wavelength, but out of phase with each other by one quarter of a wavelength, are both traveling to the right and superpose in space. Find the amplitude, wavelength, and frequency of the resulting wave in terms of the given symbols. Write the equation of the resulting traveling wave y(x, t)
A car is driven 125.0 km west and then 65.0 km southwest. What is the displacement of the car from the point of origin (magnitude and direction).
when 105 mL of water at 22 C is mixed with 68mL of water at 95 C, what is the final temperature? suppose no heat is lost to the surroundings and density of water is 1 g/mL.
The 4{rm kg} block in the figure is attached to a vertical rod by means of two strings. When the system rotates about the axis of the rod, the strings are extended and the tension in the upper string is 83N.
At time t1 = 2.00 s, the acceleration of a particle in counterclockwise circular motion is (1.00 m/s2) i + (6.00 m/s2) j. It moves at constant speed. At time t2 = 4.00 s (3/4 of a revolution later), its acceleration is (6.00 m/s2) i + (-1.00 m/s2)..
Explain how Gestalt psychologists understand perceptual organization, including the discussion of form perception, depth perception, and perceptual constancy.
A particular guitar string is supposed to vibrate at 214 Hz, but it is measured to actually vibrate at 272 Hz. By what percentage must the tension in string be changed to get the frequency to the accurate value.
an electron and a proton are each accelerated through a potential difference pf 10.0 million volts. Find the momentum ( in MeV/c) and the kinetic Energy ( in MeV) of each and compare with the results of using the classical Formular.
Their motions have equal periods, but the radius of skater A's circle is half that of skater B's circle. Evaluate the ratio of the magnitudes of the forces acting on each skater?
An 18.0 g rifle bullet travelling 245 m/s buries itself in a 3.50 kg pendulum hanging on a 3.00 m long string, which makes the pendulum swing upward in an arc. Find out the vertical and horizontal components of the pendulum's displacement.
