If only 470 Ω and 220 Ω resistors happen to be available and we need a resistance of 370 Ω, determine a combination of one 470 Ω and two 220 Ω resistors that will theoretically come within 1 Ωof the desired 370 Ω. Now with ±5% tolerance of the individual resistors used, what could be the maximum and minimum effective resistance of your circuit due to resistor tolerance?

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?
