Need help 2 Mr. Alaniz is on the edge of a majestic canyon with his guitar as he sings a power ballad of the importance of Physics. His voice effortlessly glides acrossthe canyon and strikes the rocky wall and returns as an echo. He is able to hear the echo 1.41 seconds later. How far away is the other side of the canyonfrom Mr. Alaniz?(Speed of Sound in Air: 343 m/s)O 352.64 metersO 483.63 metersO 198.83 metersO 241.81 meters24.6.79.

Careless Doug is standing on the summit of Mount Whitney (elevation 14,505 ft) while his prudent friend Hal is back at their basecamp on the shore of Iceberg Lake (elevation 12,621 ft). According to Google Maps, the horizontal distance between them is 1997 ft. Suddenly, a storm blows up, and poor Doug is struck by lightning. How much time elapses between when Hal sees the strike and when he hears it? Use 330 m/s for the speed of sound in the cold Sierra air.

Fog can greatly reduce the intensity of oncoming headlights. The distance, d, in metres, of an oncoming car whose headlights have an intensity of light, I, in lumens (lm), is given by ? = −167log⁡(1/125). a. How far away is a car whose headlight intensity is 50lm? b. If an oncoming car is 30m away, what is the intensity of its headlights? c. If the headlight intensity doubles, does this mean the car is half as far away? Explain.
One clue used by your brain to determine the direction of a source of sound is the time delay t between the arrival of the sound at the ear closer to the source and the arrival at the farther ear.Assume that the source is distant so that a wavefront from it is approximately planar when it reaches you, and let D represent the separation between your ears. (a) If the source is located at angle u in front of you , what is in terms of D and the speed of sound v in air? (b) If you are submerged in water and the sound source is directly to your right, what is t in terms of D and the speed of sound vw in water? (c) Based on the time-delay clue, your brain interprets the submerged sound to arrive at an angle u from the forward direction. Evaluate u for fresh water at 20C.
