The entrance of a science museum features a funnel into which marbles are rolled one at a time. The marbles circle around the wall of the funnel, eventually spiraling down into the neck of the funnel. The internal radius of the funnel at the top is 0.44 m. At the bottom,the funnel's neck narrows to an internal radius of 0.049 m. A 5.2 × 10-2 kg marble begins rolling in a large circular orbit around the funnel's rim at 0.28 rev/s.If it continues moving in a roughly circular path, what will the marble's angular speed be as it passes through the neck of the funnel?(Consider only the effects of conservation of angular momentum.)Answer in units of rad/s.
A source of sound waves of frequency 1.2 kHz is traveling through the air at 0.25times the speed of sound. What is the frequency of the sound received with a stationary observer if the source moves toward her?
A 20.0 kilogram toboggan with 82.2 kilogram driver is sliding down a frictionless chute directed 33.9 degree below the horizontal at 7.20 m/s, obtain what the subsequent velocity of toboggan immediately after impact
Light that has a 196 nm wavelength strikes a metal surface and photoelectrons are produced moving as fast as 0.004c. What is the work function of the metal?
A 170, 35.0 cm-diameter turntables rotate on frictionless bearings at 53.0. A 20.0 block sits at the center of turntable. A compressed spring shoots the block completely outward along a frictionless groove in the surface of the turntable.
A photon with an initial wavelength of 1.390Ã-10-11 m Compton scatters from an electron which is initially at rest. compute the kinetic energy of the scattered electron
The spectra you observe through the diffractiohn grating for these atomic vapor lamps are discrete lines of color. Recall what you observed for the spectral pattern for "white light" from a light bulb. Explain what is happening. ie. the difference..
A cannon fires a cannon ball at 853.59 m/s in a straight line that passes directly over an observer's head. how far is the cannon from the observer
A submarine with a total volume of 68.6 m3 has an inner chamber capable of taking in 16.1m3 of water (without changing the submarine's total volume). determine the maximum vertical diving acceleration of the submarine
A beam of protons is moving toward a target in a particle accelerator. This beam constitutes a current whose value is 0.51A. How many protons strike the target in 12 seconds
as a 2.0 kg object moves along the x axis the only force acting on it is given by fx 3x squared 2x newtons where x is
