![]() 1) What is the difference between the speed of light and the speed of sound? 3.0 x 10^8 - 3.4 x 10^2 2) How many times The speed of sound is approximately 3.4 x 10^2 meters per second. The speed of light is approximately 3.0 x 10^8 meters per second. ![]() As it does so, the air in the tube above the water level is heard to resonate with the tuning fork when the distance from the tube The water level is allowed to drop slowly. (a) How far below the top of the well is the surface of the water? The speed of sound in air (at the ambient temperature) is 336 m/s.Ī tuning fork is set into vibration above a vertical open tube filled with water. The sound of the splash is heard 2.40 s after the rock is released from rest. What are the possible frequencies of the unknown tuning fork?Ī rock is dropped from rest into a well. When a tuning fork of unknown frequency is sounded simultaneously with a 512 Hz tuning fork, 20 beats are heard in 4.0 seconds. A person 15 feet from a jetski, it is 75 decibels loud. The loudness, L L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d d, from the source of the sound. 2SO2(g) + O2(g) (reversible arrows) 2SO3(g) What is the value of K at this temperature? This is what I have so far: I did Kc=0.25(1100(0.0821))^-1 and got Kc=0.00276. When a tuning fork of unknown frequencyĪt 1100 K, Kp=0.25 for the following reaction. What is the amplitude of the vibration? a) 0.05 mm b) 5.0 mm c) 15.mm d) 20.mm e) 180 mm my answer: I got 10 mm but it is not listed as an option 2. A vibrating point on a spring travels 60 mm during three cycles.
