Two spinning disks have equal masses and the same angular momentum. If disk 1 has half the radius as disk 2, how does the angular speed of disk 1 compare with that of disk 2? It is twice as much. It is four times as much It is half as much It is 1/4 has much
6. Alpha and Beta are two spherical planets. The density of Alpha is twice the density of Beta, but the radius of Beta is 2 times the radius of Alpha. The gravitational acceleration at the surface of Alpha is a) Two-thirds of Beta's d) One-fifth of Beta's b) One-half of Beta's e) One-third of Beta's c) Equal to Beta's
017 10.0 points Consider two bicycle riders, A and B. The two riders have equal masses MderMBde and their respective bicycles also have sim- ilar frames, the wheels of the two bicycles have equal masses MWheel and equal radii MframeMame Finally, eheel but different mass distribu- tions: the wheels of bike A have most of their masses at the rims, Wheel A, while the wheels of bike B have their masses 'spread' evenly over the whole wheel area, Wheel B...
