Please solve all i know Bartelby rules they solve one question but please solve all questions. Two wheels A and B in the figure are connected by a belt that does not slip. The radius of Bis 7.94 times the radius of A. What would be the ratio of the rotational inertias la/l if the two wheels had (a) the same angular momentum and (b) the same rotational kinetic energy? a) Number (?). Unit's (?) b) Number ( ?) Unit's (?) 2)An automobile traveling 86.0 km/h has tires of 77.0 cm diameter. (a) What is the angular speed of the tires about their axles? (b) if the car is brought to a stop uniformly in 33.0 complete turns of the tires, what is the magnitude of the angular acceleration of the wheels? (c) How far does the car move during the braking? (Note: automobile moves without sliding) a) Numbers (?) Units (?) b) Numbers (?) Units (?) C) Numbers (?) Units (?) 3) The angular momentum of a flywheel having a rotational inertia of 0.353 kg-m² about its central axis decreases from 9.80 to 0.340 kg-m³/s in 3.40 (a) What is the magnitude of the average torque acting on the flywheel about its central axis during this period? (b) Assuming a constant angular acceleration, through what angle does the flywheel turn? (c) How much work is done on the wheel? (d) What is the magnitude of the average power done on the flywheel? a) Numbers (?) Units (?) b) Numbers (?) Units (?) c) Numbers (?) Unit's (?) d) Numbers (?) Units (?) 4) A small ball of mass 0.70 kg is attached to one end of a 0.710-m-long massless rod, and the other end of the rod is hung from a pivot. When the resulting pendulum is 37 from the vertical, what is the magnitude of the torque about the pivot? a) numbers (?) Units (?) b) numbers (?) Units (?) 5) A horizontal platform in the shape of a circular disk rotates on a frictionless bearing about a vertical axle through the center of the disk. The platform has a radius of 1.26 m and a rotational inertia of 265 kg-m² about the axis of rotation. A 73.7 kg student walks slowly from the rim of the platform toward the center. If the angular speed of the system is 1.49 rad/s when the student starts at the rim, what is the angular speed when she is 0.233 m from the center? a) numbers (?) Units (?) 6) When a man on a frictionless rotating stool extends his arms horizontally, his rotational kinetic energy:?? Please answers all questions
