A tube is sealed at both ends and contains a 0.0100-m long portion of liquid. The length of the tube is large compared to 0.0100 m. There is no air in the tube, and the vapor in the space above the liquid may be ignored. The tube is whirled around in a horizontal circle at a constant angular speed. The axis of the rotation passes through one end of hte tube, and during the motion, the liquid collects at hte other end. The pressure experienced by the liquid is the same as it would experience at the bottom of the tube, if the tube were completely filled with liquid and allowed to hang vertically. Find the angular speed (in rad/s) of the tube.
A mass moves from rest down an inclined plane with an angle of 60 degrees at the top. find the acceleration of the mass down the ramp
Many star are observed to have rotation periods that lengthenslightly with time, a phenomenon called "spin down." The rate ofslowing of the Crab Star is 3.50*10-13 s per second, which implies that if thisrate remains constant, the Crab Comet will s..

Is kinetic energy consumed in the third type of collision studies? Classify the three collision kinds as elastic, inelastic, or completely inelastic.
The current in a coil drops from 4.1 A to 2.4 A in 0.49 s. If the average emf induced in the coil is 12 mV, what is the self-inductance of the coil
A mechanic can apply a force of 240 N to each side of a tire iron a distance of L = 1.98 m apart. What is the net torque
A 0.650 MeV x-ray is Compton scattered at 90° by a free electron in an aluminum foil. a) What is the wavelength of the incident photon? b) What is the wavelength of the scattered photon? c) What is the energy of the recoiling electron?
The vibration of a diatomic molecule can be modeled as a simple harmonic oscillator. The values for the mass and force constant are 10^-26 kg and 10^3 N/m, respectively. This will work as long as the temperature is sufficiently low (assume it is in t..
