Part apart complete calculate the solubility (in grams per 1.00×102ml of solution) of magnesium hydroxide in a solution buffered at ph = 10. express your answer using two significant figures. s1 = 1.2×10−4 g/(1.00×102 ml) previous answers correct part b how does this compare to the solubility of mg(oh)2 in pure water

Argon, neon, and xenon are examples of

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.

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
