- On a hot summer day, the temperature in Anchorage reaches 75 degrees Fahrenheit. What is the speed of sound at this temperature? A: 98 m/s B: 290.4 m/s C: 173.5 m/s D: 345 m/s E: 360 m/sThere was an accident and NASA engineers are trying to sort out where two of their Mars Rovers, Tango and Foxtrot, have landed. The engineers know that landing site A is much hotter than landing site B. Unfortunately, the only working sensors on Tango and Foxtrot measure the speed of sound. If Tango measures the speed of sound at it's landing site as 240 m/s, while Foxtrot measures speed of sound as 258 m/s at it's landing site, where has each rover landed?A bat is using echolocation to find insects at night. If the bat emits a high frequency chirp and hears an echo 0.031 s later, how far away is the insect? The temperature of the air that night is 24°C.
- A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 5.83 104 Hz, and if the speed of sound in air is 343 m/s, what is the smallest insect a bat can detect?mmA sound has an intensity of 150 W/m2 at a distance of 8.50 m from the source. What is the power of the wave at its source? At what distance will its intensity drop to 1W/m2?Bats of the Vespertilionidae family detect the distance to an object by timing how long it takes for an emitted signal to reflect off the object and return. Typically they emit sound pulses 3.00 ms long and 70.0 ms apart while cruising. If an echo is heard 32.8 ms later (vsound = 331 m/s), how far away is the object? When an object is only 39.2 cm away, how long will it be before the echo is heard? When an object is only 39.2 cm away, the bat __________ able to detect the echo.
