Aplatform is rotating at an angular speed of 2.5 rad/s. a block is resting on this platform at a distance of 0.28 m from the axis. the coefficient of static friction between the block and the platform is 0.74. without any external torque acting on the system, the block is moved toward the axis. ignore the moment of inertia of the platform and determine the smallest distance from the axis at which the block can be relocated and still remain in place as the platform rotates

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
