An aluminum rod is designed to break when it is under a tension of 600 n. one end of the rod is connected to a motor and a 12-kg spherical object is attached to the other end. when the motor is turned on, the object moves in a horizontal circle with a radius of 6.0 m. if the speed of the motor is continuously increased, at what speed will the rod break? ignore the mass of the rod for this calculation.

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.
