A 22.4 g silver ring (cp = 234 J/kg·°C) is heated to a temperature of 77.4°C and then placed in a calorimeter containing 4.08 ✕ 10-2 kg of water at 24.0°C. The calorimeter is not perfectly insulated, however, and 0.132 J of energy is transferred to the surroundings before a final temperature is reached. What is the final temperature?

Aplanet of mass m 6.75 x 1024 kg is orbiting in a circular path a star of mass m 2.75 x 1029 kg. the radius of the orbit is r 8.05 x107 km. what is the orbital period (in earth days) of the planet tplanet?

Distinguish between a transverse wave and a longitudinal wave.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
