The "zone of avoidance" a) accounts for the absence of any planet between the orbits of mars and jupiter prevents collisions between planets in the solar system. b) bscures visual observation through the plane of the milky way d) is the minímum distance an object must have from a black hole to avoid gravitational capture the regions that remained barren during evolution of life on earth. e)

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?
