90 points The system shown above is released from rest. The horizontal surface is frictionless, and there is sufficient friction for the uniform hoop to roll smoothly down the ramp. The hoop has a mass of 6.2kg and a radius of 27 cm. The pulley is a non - uniform disk with a mass of .25 kg, radius of 6.2 cm, and B = .38. The rope does not slip on the pulley. Determine the displacement of the box when the kinetic energy of the pulley is 443J.

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.
