Most of the galaxies in the universe are observed to be moving away from Earth. Suppose a particular galaxy emits orange light with a frequency of 5.000 × 1014 Hz. Part A If the galaxy is receding from Earth with a speed of 4750 km/s, what is the frequency of the light when it reaches Earth? Express your answer to four significant figures and include appropriate units. µA ? Value Units
Each piston of an engine makes a sharp sound every other revolution of the engine. (a) How fast is a race car going if its eight-cylinder engine emits a sound of frequency 750 Hz, given that the engine makes 2000 revolutions per kilometer? (b) At how many revolutions per minute is the engine rotating?
Your ear is capable of differentiating sounds that arrive at each ear just 0.34 ms apart, which is useful in determining where low frequency sound is originating from. (a) Suppose a low-frequency sound source is placed to the right of a person, whose ears are approximately 18 cm apart, and the speed of sound generated is 340 m/s. How long is the interval between when the sound arrives at the right ear and the sound arrives at the left ear? (b) Assume the same person was scuba diving and a low-frequency sound source was to the right of the scuba diver. How long is the interval between when the sound arrives at the right ear and the sound arrives at the left ear, if the speed of sound in water is 1500 m/s? (c) What is significant about the time interval of the two situations?
(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)

Do the all please 1.) In the example of the cannons at USMA from the speed of sound content in this module, the source (cannon) and the observer (me) were stationary. Let us assume the wavelength of the sound the cannon made was 1.302m. Consider three observers that are 1200km away from the cannons on that day:Observer A: stationaryObserver B: in a vehicle moving with speed 20.00 m/s directly away from the cannonObserver C: in a vehicle moving with speed 20.00 m/s directly toward the cannon What time passes between the firing of the cannon and the arrival of its sound at the position of observer A? 2.) In the example of the cannons at USMA from the speed of sound content in this module, the source (cannon) and the observer (me) were stationary. Let us assume the wavelength of the sound the cannon made was 1.710m.

SOLVE STEP BY STEP IN DIGITAL FORMAT DOPPLER EFFECT 7. A patrol moves with a constant speed, sounding its siren with a frequency of 600 Hz. An observer at rest listens to the approach of the patrol with an apparent frequency of 680 Hz. If the temperature of that place is 18° F, calculate: a) The speed of the patrol. b) The apparent frequency you would hear when moving away from it.
Please answer all 3 sub-parts 1. You let go of a 0.3kg ball from a height of 2m. When the ball bounces off the ground, it loses 15% of its energy as sound. a) How much energy does the ball lose during the bounce? b) How high does the ball bounce back up after hitting the ground? c) What initial speed would the ball need to be thrown downward at so that it would bounce back up to a maximum height of 2m?
