A 14.5 gram, 78.6 centimeter long steel guitar string is vibrating in its fourth harmonic. It induces a standing wave in a nearby 69.3 centimeter metal pipe open at one end. The standing sound wave in the pipe corresponds to the pipe's fundamental frequency.
What is the tension on the steel guitar 'string'? (in Newtons)
An airplane is flying in a horizontal circle at a speed of 100 m/s. The 80.0-kg pilot does not want her radial acceleration to exceed 7g. (a) What is the least radius of the circular path? (b) At this radius, what is the force causing the centripe..

An engineer is designing a runway for a new airport. Of the planes which will use the airport, the lowest acceleration rate will be 3 m/s2. Assuming the minimum acceleration, what is the minimum allowed length for the runway
Two point charges Q1, and Q2 are place exactly on the x axis at -x1. A second particle Q2 is placed at +x2 on the positive x axis. What is the total E field at the origin
A parallel-plate capacitor has a capacitance of c1 = 3.5 uF when filled with air and c2 = 23 uF when filled with a dielectric oil at potential difference of 12 V. What is the permittivity of this oil
You have a string with a mass of 0.0131 kg. You stretch the string with a force of 9.31 N, giving it a length of 1.89 m, What is the wavelength of the standing wave you create in the string
While you are sitting on a chair at the edge of a 1.8 m deep swimming pool, your eyes are 1.7 m above the surface of the water. What is the horizontal distance between you and the acorn?
Two boats start together and race across a 56km wide lake and back. Boat A goes across at 56 km/h and returns at 56km/h. Boat B goes across at 28km/h, and its crew, realize how far behind it is getting.
Now a peg is placed 4/5 of the way down pendulum's path so that when the mass falls to its vertical position it hits and wraps around the peg. As it wraps around the peg and attains its maximum height it ends a distance of 3/5 L below its starting po..
