Two wheels are free to spin about the same axle. the moment of inertia of wheel 1 is 2.66 kg m2, and the moment of inertia of wheel 2 is 1.18 kg m2. when the axle is in its initial position, wheel 1 spins clockwise with an angular speed of 35.00 rad/s, and wheel 2 spins counterclockwise with an angular speed of 38.60 rad/s. (a) what is the magnitude of the angular momentum of the two disk system in this initial position?
kg m2/s

(b) the axle is rotated, or tilted, by 180° to its final position. what is the magnitude of the vector quantity ? l?
kg m2/s

(c)the wheels are returned to their initial position, and wheel 2 spins clockwise at 39.00 rad/s. what is the magnitude of the angular momentum of the two disk system in this new configuration?
kg m2/s

(d)the axle is once again rotated, or tilted, by 180° to its final position. what is the magnitude of the vector quantity ? l?
kg m2/s

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
