Print CalculatorPeriodic Table Question 8 of 24 Map d Sapling Learning Albert stands on a frictionless turntable, holding a bike wheel. Both Albert and the wheel are initially stationary. Albert gives the bike wheel a good spin, and it begins rotating clockwise. If the bike wheel has a final angular momentum of one unit, clockwise, what is the final angular momentum had by the rest of the system (i.e. Albert and the turntable)? O two units, counterclockwise O zero units O one unit, clockwise O two units, clockwise O one unit, counterclockwise Albert flips the bike wheel upside down, so that it is now spinning the other way and has one unit of angular momentum in the counterclockwise direction. By how much does the angular momentum of Albert (plus turntable) change during the process of flipping the wheel? O zero units O one unit, clockwise O two units, counterclockwise O two units, clockwise O one unit, counterclockwise Previous 8 Give Up & View Solution Check Answer extExit Hint

Explanation / Answer

one unit counterclockwise

as per conservation of momentum ,

total initial angular momentum = total final angular momentum

0 = angular momentum of bike wheel + angular momentum of rest of the system

angular momentum of rest of the system = - angular momentum of bike wheel

as per conservation of momentum

change in angular momentum of wheel = - change in angular momentum of rest of the system

final angular momentum - initial angular momentum = - change in angular momentum of rest of the system

- 1 - 1 = - change in angular momentum of rest of the system

change in angular momentum of rest of the system = 2

2 units clockwise
