Awheel on a game show is given an initial angular speed of 1.12 rad/s . it comes to rest after rotating through 0.75 of a turn.

part a. find the average torque exerted on the wheel given that it is a disk of radius 0.61 m and mass 5.4 kg.

part b. if the mass of the wheel is doubled and its radius is halved, will the angle through which it rotates before coming to rest increase, decrease, or stay the same?

(assume that the average torque exerted on the wheel is unchanged.)

will increase? will decrease? will stay same?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
