Asubmerged submarine alters its buoyancy so that it initially accelerates upward at 0.325 m/s^2. what is the submarine's average density at this time? (hint: the density of sea water is 1.025x10^3 kg/m^3.)

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
