Experiments show that the ground spider drassodes cupreus uses one of its several pairs of eyes as a polarization defector. in fact, the two eyes in this pair have polarization directions that are at right angles to one another. suppose linearly polarized light with an intensity of 900w/m2 shines from the sky onto the spider, and that theintensity transmitted by one of the polarizing eyes is 187 w/m2.(a) for this eye, what is the angle between thepolarization direction of the eye and the polarization direction ofthe incident °

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 fact supports the conclusion that there will be fewer farm managers in the future? a) a farmer manager’s duties vary by the type of farm. b) farm technology is replacing some administrative jobs c) farm managers often need experience but not education. d) administrative duties include budgeting and training staff.
