A volume of 200.0 cm3 of water at a temperature of 4°C is in a container with a 1000-cm3 capacity. The container and its contents are heated to 95°C. What is the final volume of water in the container? Disregard any expansion of the container itself. βwater = 210 x 10-6 (°C)-1.

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j

Amoving electron has kinetic energy k1. after a net amount of work w has been done on it, the electron is moving one-quarter as fast in the opposite direction. (a) find w in terms of k1. (b) does your answer depend on the final direction of the electron's motion?
