An object of mass m rests on a frictionless surface and is attached to a horizontal ideal spring with spring constant k. The system oscillates with amplitude A. The oscillation frequency of this system can be increased by: (a) decreasing k.
(b) decreasing m.
(c) increasing A.
(d) More than one of the above.

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

If a balloon is taken outside on a very cold day, what will occur?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
