Awave on the ocean has a wavelength of 200 m, the wave is a deep-water wave only if the water is deeper than 200 m if the water is deeper than 100 m if the water is less than 100 m deep if the water is shallower than 50 m

From center station, a train departs every 30 minutes on the fast line and a train departs every 50 minutes on the state line. if two trains depart from center station at 8: 00 a.m., one on each of the two lines, what is the next time that two trains, one on each line, will depart at the same time?

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
