You are standing next to an old well. You want to know how far down the surface of the water is (you are very thirsty), so you hold a rock above the well and drop it. You measure the amount of time between when you release the rock and when you year the splash produced when the stone hits the water at the bottom of the well to be T. You know that the speed of sound in air is vs and the acceleration due to gravity is g. Neglecting air resistance, find the depth of the well.

A man drops a rock into a well. (a) The man hears the sound of the splash 2.40 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water? (b) What If? If the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated?
A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P4.22). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?
CASE STUDY On planet Betatron, mass is measured in bloobits and length in bots. You are the Earth representative on the interplanetary commission for unit conversions and find that 1 kg = 0.23 bloobits and 1 m = 1.41 bots. Express the density of a raisin (2 103 kg/m3) in Betatron units.
The Bernoiulli effect can have important consequences for the design of buildings. For example, Wind can blow aorund a skyscraper at remarkably high speed, creating low pressure. The higher atmospheric pressure in the still air inside the buildings can cause windowspanes that fell many stories to the sidewalk below a) Suppose a horizontal wind blows with a speed of 11.2 M/s outside a large pabe of plate glass with dimensions 4.00m x 1.50m Assume the density of the air to be constant at 1.20kg/m3 The air inside the building is at atmospheric pressure. What is the total force exerted by air on the windowpane? b) What if a sencond skyscraper is built nearby, the airspeed can be especially high where wind passes through the narrow separation between the buildings. Solve part (a) again with a wind speed of 22.4m/s, twice as high

Item 4 (Figure 1)A parallel-plate vacuum capacitor is connected to a battery and charged until the stored electric energy is U. The battery is removed, and then a dielectric material with dielectric constant K is inserted into the capacitor, filling the space between the plates. Finally, the capacitor is fully discharged through a resistor (which is connected across the capacitor terminals). Figure 1 of 2 Part A Find U₁, the the energy dissipated in the resistor. Express your answer in terms of U and other given quantities. ► View Available Hint(s) - ΑΣΦ U₁ = Submit Part B U₁ = Submit Provide Feedback ? Consider the same situation as in the previous part, except that the charging battery remains connected while the dielectric is inserted. (Figure 2) The battery is then disconnected and the capacitor is discharged. For this situation, what is U₁, the energy dissipated in the resistor? Express your answer in terms of U and other given quantities. ► View Available Hint(s) —| ΑΣΦ
On December 26, 2004, a great earthquake occurred off the coast of Sumatra and trig- gered immense waves (tsunami) that killed some 200, 000 people. Satellites observing these waves from space measured 800 km from one wave crest to the next and a period between waves of 1.0 hour. What was the speed of these waves in m/s and km/h? Does your answer help you understand why the waves caused such devastation?
Scurrilous con artists have been known to represent goldplatedtungsten ingots as pure gold and sell them to thegreedy at prices much below gold value but deservedly farabove the cost of tungsten. With what accuracy must you beable to measure the mass of such an ingot in and out of waterto tell that it is almost pure tungsten rather than pure gold?

10.0 m^3 of oil is spilled into a body of water. What is the surface area of the resulting oil slick, assuming the oil molecules all float on top of the water, lining up right next to each other so that the slick is one-molecule thick, and each oil molecule occupies the space of a cube 0.45 um on each side?
