Problem 1: You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T = 29.5° C. To determine how far you are away from the canyon wall you yell “Hello" and hear the echo t = 2.4 s later. Randomized Variables T = 29,5° C t = 2.4 s Part (a) Calculate the speed of sound in the valley in meters per second, assuming the speed at 0° C is 332 m/s.

Expert Solution
Step 1

Given data

The outdoor temperature is T = 29.5°C

The time of echo is t = 2.4 s

The speed of sound at 0°C is vo°C  = 332 m/s

The temperature of the air in the cold morning is T2 = - 4.5 °C
