Abox is pushed down at an angle of 32 degrees on a rough surface. the box moves to the right.what equation should be used to find the net force in the y-direction? answers: a. fnet,y = fn - fgb. fnet,y= fp - ffc. fnet,y = fn-fg- fpcos(32)d. fnet,y = fn-fg-fpsin(32)

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
