Q. A centrifuge rotor rotating at 10,000 rpm is shut off and is eventually brought uniformly to rest by a frictional torque of 1.00 m?N. If the mass of the rotor is 4.70 kg and it can be approximated as a solid cylinder of radius 0.0780 m, through how many revolutions will the rotor turn before coming to rest?
Q. A 13.0 kg bucket of water of is suspended by a rope wrapped around a windlass, which is a solid cylinder 0.400 m in diameter with mass 14.0 kg. The cylinder is pivoted on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls 10.0 m to the water. Neglect the weight of the rope.(a) What is the tension in the rope while the bucket is falling? (b) With what speed does the bucket strike the water? (c) What is the time of fall? (d) While the bucket is falling, what is the force exerted on the cylinder by the axle?
How much time passes by they collide
Suppose that the light is incident at right angles to the film. what is the minimum distance from the slits to the screen when 580 nm light is used.
A proton is initially at rest at a point where the potential is 459 V. Sometime later the proton is at a point where the potential is 218 V. If no force other than an electrostatic force acts on the proton, what is its final kinetic energy.
Next you eliminate the 11 kg mass, place the rod horizontally, and strike one end with a hammer. How much time t would elapse before a microphone at the other end of the bar will detect a disturbance.
What was the absorbed dose in the carbon walls? The average mass stopping powers of graphite and CO2 for the photons are, respectively, 1.648 and 1.680 MeV cm^2/g.
You can ignore friction between the sled and surface of the pond. Use the work-energy theorem to find the speed of the sled at 3.00 m.
The maximum distance from Earth to the Sun (at our aphelion) is 1.521 x 10^11 m and the distance of closest approach (at perihelion) is 1.471 x 10 ^11 m. Assume the Earth's orbital speed at perihelion is 3.027 x 10 ^ 4 m/s. (overlook the effect of th..
