In a study designed to prepare new gasoline-resistant coatings a polymer chemist dissolves 6.053 g of poly(vinyl alcohol) in enough water to make 100.0 ml of solution. at 25°c, the osmotic pressure of this solution is 0.272 atm. what is the molar mass of the polymer sample? enter your answer in scientific notation.

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output

What is the increase in density of a medium due to wave travel?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
