Hey guys, I just took AAMC VI and did well on physical sciences--unfortunately by guessing...so here are a few questions I could use help with... The ionization constant, to a first approximation, of H(2)S is: A) Near zero B) Much less than 1 C) about 1 D) much more than 1 The motion for small displacements x is characterized by two dimensional constants, K and M. Identify by dimensional argument the correct formula from which the period T can be calculated. maximal displacements x = -A and A A) (T/pi)square = 4K/M B) (T/pi)square = 4K*M C) (T/pi)square = 4M/K D) (T/pi)square = 4/(K*M) The spring constant K can be computed from the internal energy E and the amplitude A by: A) K = A squared * E B) K = A * E C) K = E/A D) K = E/A squared How many grams of lead(II) Iodide are present in 100ml of a saturated aqueous solution? (Solubility S = 1.89 x 10(-3)) A) .0410 g B) .0871 g C) 2.470 g D) 8.71 g In a healthy person standing at rest, a comparison of arterial blood pressure measured in the arm with taht measured in the leg shows that the pressure is : A) lower, because the blood flow rate is less B) lower, because the viscous flow resisitance causes pressure loss C) the same, because viscous pressure loss precisely compensates the hydrostatic pressure increase D) greater, because the column of blood betwen the arm and the leg has a hydrostatic pressure any help is appreciated! thanks!
