Chapter 16: Q. 27 (page 452)

What is the speed of sound in air (a) on a cold winter day in Minnesota when the temperature is –25°F, and (b) on a hot summer day in Death Valley when the temperature is 125°F?

Short Answer

Expert verified

Part a

The speed of sound in the air on a cold winter day in place M is 311m/s.

Part b

The speed of sound in the air on a hot summer day in place D is361m/s.

Step by step solution

01

Given information

The temperature on a cold winter day -25°F=241.48K

The temperature on a hot summer day is125°F=325K

02

Part a 

The speed of sound in the air on a cold winter day is

v=331m/s×241.48273=311m/s

Therefore, the speed of sound in the air on a cold winter day in place M is 311m/s.

03

Part b

The speed of sound in the air on a hot summer day is

v=331m/s×325273=361m/s

Therefore, the speed of sound in the air on a hot summer day in place D is361m/s.

You have just been pulled over for running a red light, and

the police officer has informed you that the fine will be \(250. In

desperation, you suddenly recall an idea that your physics professor recently discussed in class. In your calmest voice, you tell the officer that the laws of physics prevented you from knowing that the light was red. In fact, as you drove toward it, the light was Doppler shifted to where it appeared green to you. “OK,” says the officer, “Then I’ll ticket you for speeding. The fine is \)1 for every 1 km/h over the posted speed limit of 50 km/h.< How big is your fine? Use 650 nm as the wavelength of red light and 540 nm as the wavelength of green light.
