105. •Medical An ultrasound machine can measure blood flow speeds. Assume the machine emits acoustic energy at a frequency of 2.0 MHz, and the speed of the wave in human tissue is taken to be 1500 m/s. What is the beat frequency between the transmitted and reflected waves if blood is flowing in large arteries at 0.020 m/s directly away from the sound source?

The low-frequency speaker of a stereo set hag a surface area of 0.05 m2 and produces 1W 0f acoustical power. What is the intensity at the speaker? If the speaker projects sound uniformly in all directions, at what distance from the speaker is the intensity 0.1W/m2 ?
(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, they compare the arrival times of S and Pwaves, which travel at different speeds. Figure 16.48) If S and Pwaves travel at 4.00 and 7.20km/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.)

A dolphin is able to tell in the dark that the ultrasound echoes received from two sharks come from two different objects only it the sharks are separated by 3.50 m, one being that much farther away than the other. (a) If the ultrasound has a frequency of 100 kHz, show this ability is not limited by its wavelength. (b) If this ability is due to the dolphin's ability to detect the arrival times of echoes, what is the minimum time difference the dolphin can perceive?
Ultrasound reflected from an oncoming bloodstream mat is moving at 30.0 cm/s is mixed with the original frequency of 2.50 MHZ to produce beats. What is the beat frequency? (Assume than the frequency of 2.50 MHz is accurate to seven significant figures.)
1. When dolphin swims close to its prey, it transmits sound waves to figure outdetails (like direction where the fish is moving) of its prey. Now, if the frequency ofthe reflected waves has increased, would the dolphin catch up its prey or fall behind?

A tsunami is a sort of pulse or “wave packet” consisting ofseveral crests and troughs that become dramaticallylarge as they enter shallow water at the shore. Supposea tsunami of wavelength 235 km and velocity 550 km/htravels across the Pacific Ocean. As it approaches Hawaii,people observe an unusual decrease of sea level in theharbors. Approximately how much time do they have torun to safety? (In the absence of knowledge and warning,people have died during tsunamis, some of them attractedto the shore to see stranded fishes and boats.)
