You are working on your family's farm during a summer vacation from school. Your father wants to know how far below ground level the water surface is in a water well. He asks you to determine the depth. He has no suggestions as to how to do this. You look down into the well but cannot see the water surface, so you sit down to think about the challenge. You come up with a solution! You open a frequency generator app on your smartphone, set the volume at its maximum position, and hold the phone over the opening to the well. As you vary the frequency of the sine wave sound emitted by the phone, you notice successive resonances at 54.00 Hz and 59.68 Hz. From these values, you determine the depth of the well. (Enter your answer in m.)

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
