Ou are assigned the design of a cylindrical, pressurized water tank for a future colony on Mars, where the acceleration due to gravity is 3.71 m/s2m/s2. The pressure at the surface of the water will be 140 kPakPa , and the depth of the water will be 13.6 mm . The pressure of the air outside the tank, which is elevated above the ground, will be 86.0 kPakPa . Part A Find the net downward force on the tank's flat bottom, of area 2.45 m2m2 , exerted by the water and air inside the tank and the air outside the tank. Assume that the density of water is 1.00 g/cm3g/cm3. Express your answer in newtons.

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.
