- A fireworks rocket explodes at a height of 100 m above the ground. An observer on the ground directly under the explosion experiences an average sound intensity of 7.00 102 W/m2 for 0.200 s. (a) What is the total amount of energy transferred away from the explosion by sound? (b) What is the sound level (in decibels) heard by the observer?arrow_forwardA police car is traveling east at 40.0 m/s along a straight road, overtaking a car ahead of it moving east at 30.0 m/s. The police car has a malfunctioning siren that is stuck at 1 000 Hz. (a) What would be the wavelength in air of the siren sound if' the police car were at rest? (b) What is the wavelength in front of the police car? (c) What is it behind the police car? (d) What is the frequency heard by the driver being chased?arrow_forwardA tunnel under a river is 2.00 km long. (a) At what frequencies can the air in the tunnel resonate? (b) Explain whether it would be good to make a rule against blowing your car horn when you are in the tunnel.arrow_forward
- (a) What frequency is received by a person watching an oncoming ambulance moving at 110 km/h and emitting a steady 800—Hz sound from its siren? The speed of sound on this day is 345 m/s. (b) What frequency does she receive after the ambulance has passed?arrow_forwardAir temperature in the Sahara Desert can reach 56.0°C (about 134°F). What is line speed of sound in air at that temperature?arrow_forward(a) You are driving down the highway in your car when a police car sounding its siren overtakes you and passes you. If its frequency at rest is f0, is the frequency you hear while the car is catching up to you higher or lower than f0? (b) What about the frequency you hear after the car has passed you?arrow_forward
- . A sonic depth gauge is placed 5 m above the ground. An ultrasound pulse sent downward reflects off snow and reaches the device 0.03 seconds after it was emitted. The air temperature is — 20°C. (a) How far is the surface of the snow from the device? (b) How deep is the snow?arrow_forwardA wave traveling on a Slinky® mat is stretched to 4 m takes 2.4 s to travel the length at me Slinky and back again. (a) What is the speed of the wave? (b) Using the same Slinky stretched to the same length, a standing wave is created which consists of three antinodes and four nodes. At what frequency must the Slinky be oscillating?arrow_forwardA sound wave is modeled with the wave function P=1.20Pasin(kx6.28104s1t) and the sound wave travels in air at a speed of v=343.00 m/s. (a) What is the wave number of the sound wave? (b) What is the value for P(3.00 m, 20.00 s)?arrow_forward
- A driver travels northbound on a highway at a speed of 25.0 m/s. A police car, traveling southbound at a speed of 40.0 m/s, approaches with its siren producing sound at a frequency of 2 500 Hz. (a) What frequency does the driver observe as the police car approaches? (b) What frequency does the driver detect after the police car passes him? (c) Repeat parts (a) and (b) for the case when the police car is behind the driver and travels northbound.arrow_forwardA sound wave traveling in 20°C air has a pressure amplitude of 0.5 Pa. What is the intensity of the wave?arrow_forwardWrite an expression that describes the pressure variation as a function of position and time for a sinusoidal sound wave in air.
