A 5.0 m massless rod is held in place at a pivot point. The rod has a small mass of 2.5 kgs attached to it. It is pulled up by an angle of 25 degrees from the horizon and then released. Required:
a. Rank the magnitude of the gravitational potential energy of the ball from greatest to lowest and explain your reasoning.
b. If friction is negligible what is the tension on the rod when + D the mass is at its lowest point?

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.
