You stand at the top of a deep well. To determine the depth,
D, of the well you drop a rock from the top of the well
and listen for the splash as the rock hits the water’s surface. The
sound of the splash arrives t = 4.3 s after you drop the
rock. The speed of sound in the well is vs =
336 m/s

When you drop a rock into a well, you hear the splash 2.0 seconds later. How deep is the well? If the depth of the well were doubled, would the time required to hear the splash be greater than, less than, or equal to 4.0 seconds? Please explain why

You drop a rock into a deep well and 4.6 s later hear the splash. How far down is the water? Neglect the travel time of the sound. Express your answer using two significant figures.

1). You drop a stone from rest into a well that is 5.2m deep. How long does it take before you hear the splash? 2). A street musician sounds the A string of his violin, producing a tone of 440 Hz, What frequency does a bicyclist hear as he a) approaches and b) recedes from the musician with a speed of 11.0 m/s? 3). One of the harmonics on a string 1.30m long has a frequency of 15.60 Hz. The...

You are standing a distance d
(2m) directly in front of one of two identical speakers, being
driven by the same signal generator, that are a distance h (5m)
apart. You walk in the positive direction starting at y=0 m, along
a line parallel to the line joining the two speakers. The speed of
sound is 340 m/s and the frequency is 170 HZ. As you walk, how many
times and where will you hear a maximum sound?

Imagine that we release a rock of mass m (which is initially at rest) at the surface of a lake and measure its position and velocity as functions of time while it sinks. The rock moves under the influence of three forces: gravity, buoyancy, and viscous drag. Let y represent the vertical position of the sinking rock, with the surface of the lake at y -0, and positive y upwards The net force on the rock is F =-[m-mdisplaced where...

PROBLEM #2: STANDING WAVE PATTERNS While talking to a friend on the phone you play with the telephone cord. As you shake the cord, you notice the ends of the cord are stationary whi vibrates back and forth; you have a standing wave. As you change the motion of your hand, a new pattern develops in which the middle of the cord is stationary while the rest of the cord vibrates wildly. You decide to...

(8 pts) Carbon dioxide in the atmosphere dissolves in water to establish an equilibrium that can increase the acidity of aqueous solutions in the environment. This equilibrium is CO2(g) = CO2 (aq), Kn= 3.1 x 10-2 at 25°C. Kh is called the Henry's law constant, which relates the solubility of the gas CO2 in the aqueous solution, [CO2), to the partial pressure of CO2 over the solution, p(CO2): [CO2] (M)= Kn · p(CO2) (atm) During the preceding decades, the atmospheric...
