A particle is constrained to move (without friction) on a circular wire rotating by constant angular speed ω about a vertical diameter. Discover the equilibrium position of the particle, and compute the frequency of small oscillations around this position. Discover and interpret physically a critical angular velocity ω=ωc that divides the particle's motion into two distinct types. Construct phase diagrams for the two cases ω<ωc and ω>ωc.
A centrifuge is a device in which a small container of material is rotated at high speed on a circular path. such a device is used in medical laboratories, for instance, to cause the more dense red blood cells to settle through the less dense bloo..
A 25g ball is fired with an initial speed v1 toward a 150g ball that is hanging motionless from a 1.30m string. The balls have a perfectly elastic collision. As a result, 150 g ball swings out until the string makes an angle of 37° with vertical. ..
A liquid hydrogen target of the thickness of 1cm and density of 0.071 g/cm3 is bombarded with a rare isotope beam of 60Ca with an intensity of 100 counts per second. The reaction p(60Ca,60Ca(2+))p’ is observed by detecting the photons from the dec..
