An infinite uniform non-multiplying medium has the following properties: diffusion length 8cm, diffusion coefficient 1.4 cm. there is an infinite plane source on the y-z of plane strength 13 106cm-2.s-1 and two point sources on the x. y plane as follows source: 82 = 107 s-1 at (x, y) = (1,0)cm s,-107s-1 at (x, y) = (2,0)cm a. calculate the total flux at the point (xn =(1.5,0.5) cm on the x-y plane. flux- b. what is the magnitude and the direction of the total current at the same point current magnitude- current directions:

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?

Which of these metals are magnetic?

The first-order reaction a→2b+c has rate constant 0.538 s−1. if the initial concentration of a is 0.867 mol l−1, what is the half-life of the reaction in seconds? remember to use correct significant figures in your answer (round your answer to the nearest hundredth). do not include units in your response.
