The clarinet is well modeled as a cylindrical pipe that is open at one end and closed at the other. Find the wavelength and frequency of the third normal mode of vibration of a clarinet\'s air column with effective length of 0.385 m. Take 344 m/s for the speed of sound inside the instrument.
A 48 kg skier starts from rest at a height of H = 27 m above the end of the ski-jump ramp. As the skier leaves the ramp, his velocity makes an angle of 28° with the horizontal. avoid the effects of air resistance and assume the ramp is frictionles..
What is the lenght of the driveway. An electric field = (89000 N/C, right) causes the ball in the figure below to hang at a 20° angle. The ball's mass is 4.7 g. What is the charge on ball.
A hydraulic lift consists of two pistons that connect to each other by an incompressible fluid. If one piston has an area of 0.49 m^2 and the other an area of 6.2m^2, how big a mass can be raised by a force of 220N exerted on the smaller piston.
Heather and Jerry are standing on a bridge 51 above a river. Heather throws a rock straight down with a speed of 12. Jerry, at accurately the same instant of time, throws a rock straight up with the same speed. Ignore air resistance.
The spheres are touched together and are then returned to their original separation d. Illustrate what is the force between them.
What is the velocity of 5.5kg object with a force of 2.5N while it reaches 6.0 meters, assuming the velocity at zero meters is zero.
After the Sun exhausts its nuclear fuel, its ultimate fate might be to collapse to a white dwarf state. In this state, it would have about the same mass as it has now, but its radius would be equal to the radius of the Earth.
A bullet of mass 0.0025 kg moving at 581 m/s impacts a large fixed block of wood and travels 5.40 cm before coming to rest.
A guitar string with a mass of 12 g is 80 cm long and attached to the guitar at two points separated by 65 cm. What is the frequency of its fundamental note when it is placed under a tension of 170 N? Answer A) 74 Hz B) 82 Hz C) 93 Hz D) 150 Hz E)..
A car traveling at 21 runs out of gas while traveling up a 21 slope.How far up the hill will it coast before starting to roll back down.
What is the magnitude of the electrostatic force the molecule exerts on it?
A force F = 200i - 400j + FZ k N, is acting through point A(0,0,0) m. If F creates a moment component of -3000 Nm in the direction of a line passing from point B (2,4,5) m to point C(-3,6,8) m
