Three batches of radish seeds, each with a starting weight of 1.5 grams (g, dry) were placed in Petri dishes and provided with light or water or both. After 1 week, the material in each dish was dried and weighed. The resulting weights were: 1) Light, no water 1.48 g; 2) light and water, 3.28 g; 3) no light, water 1.17 g.

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
