A block with a speaker bolted to it is connected to a spring having spring constant k and oscillates as shown in the figure below. The total mass of the block and speaker is m, and the amplitude of this unit's motion is A. The speaker emits sound waves of frequency f. (a) Determine the highest frequency heard by the person to the right of the speaker. (Use any variable or symbol stated above along with the following as necessary: v for the speed of sound.) f ' max v - v тах (b) Determine the lowest frequency heard by the person to the right of the speaker. (Use any variable or symbol stated above along with the following as necessary: v for the speed of sound.) f' min v + v. max (c) If the maximum sound level heard by the person is ß when the speaker is at its closest distance d from him, what is the minimum sound level heard by the observer? (Use any variable or symbol stated above along with the following as necessary: v for the speed of sound. Do not include any units in your answer.) fo + 2 log(2 Bmin 10

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot mov…
