I once again can not read this. the sentence just cuts off. please do a different format. this is the second time I have had a problem with this question.
During a cricket game one fan is located directly behind wickets, 18.3 m from the batter and a second fan, is located in the centerfield bleachers, 127 m from the batter. Both fans observe the batter strike the ball at the same time (because the speed of light is about a million times faster than that of sound), but the fan behind home plate hears the sound first.
a) What is the time difference between hearing the sound at the two locations? Use 345 m/s as the speed of sound.
b) As the batter hits the ball at a speed of 43,556 m/s and a 220 Hz sound is emitted. If the ball moves in the direction of the first fan what frequency would she observe?
A human cannot hear sound at a frequency of 100 kHz or sound at 102 kHz. But if you into a room in which two sources are emitting sound waves, one at 100 kHz and the other at 102 kHz, you'll hear sound. Why? Explain

- During a 4th of July celebration, an M80 firework explodes on the ground, producing a bright flash and a loud bang. The air temperature of the night air is TF=90.00F . Two observers see the flash and hear the bang. The first observer notes the time between the flash and the bang as 1.00 second. The second observer notes the difference as 3.00 seconds. The line of sight between the two observers meet at a right angle as shown below. What is the distance x between the two observers?arrow_forwardDuring a thunderstorm, a frightened child is soothed by learning to estimate the distance to a lightning strike by counting the time between seeing the lightning and hearing the thunder (Fig. P2.25). The speed vs of sound in air depends on the air temperature, but assume the value is 343 m/s. The speed of light c is 3.00 108 m/s. a. A child sees the lightning and then counts to eight slowly before hearing the thunder. Assume the light travel time is negligible. Estimate the distance to the lightning strike. b. Using your estimate in part (a), find the light travel time. Is it fair to neglect the light travel time? c. Think about how time was measured in this problem. Is it fair to neglect the difference between the speed of sound in cold air (vs at 0C = 331.4 m/s) and the speed of sound in very warm air (vs at 40C = 355.4 m/s)?arrow_forwardSubmarine A travels horizontally at 11.0 m/s through ocean water. It emits a sonar signal of frequency f = 5.27 103 Hz in the forward direction. Submarine B is in front of submarine A and traveling at 3.00 m/s relative to the water in the same direction as submarine A. A crewman in submarine B uses his equipment to detect the sound waves (pings) from submarine A. We wish to determine what is heard by the crewman in submarine B. (a) An observer on which submarine detects a frequency f as described by Equation 16.46? (b) In Equation 16.46, should the sign of vs be positive or negative? (c) In Equation 16.46, should the sign of vo be positive or negative? (d) In Equation 16.46, what speed of sound should be used? (e) Find the frequency of the sound detected by the crewman on submarine B.arrow_forward
- A physicist at a fireworks display times the lag between seeing an explosion and hearing its sound, and finds it to be 0.371 s. How far away in meters is the explosion if air temperature is 24.0°C and if you neglect the time taken for light to reach the physicist? Assume the speed of sound in 0°C air is 331 m/s. Type your answer.....arrow_forwardAn automatic focus camera is able to focus objects using ultrasonic sound waves.The camera sends out sound waves that reflect ff distance objects and returns to the camera. A sensor detects the time it takes for the waves to return and then determines the distance of an objects from the camera.

- VBR = 50 m/s a) b) c) d) VAR = 30 m/s Two cars are ini- tially 960m apart and are approaching each other at speeds of 50m/s and 30m/s relative to the road. Car B honks its horn, sending a packet of sound traveling at 340m/s relative to the road towards Car A. The sound wave will bounce off either car and instantaneously keep traveling at 340m/s relative to the road forwards or backwards at all times. (Note: Many parts of this problem do not require the previous part's solution to solve it) Find AB How long after the horn is sounded until the two cars have collided?
