Alarge fish and a small cat stare at each other from either side of a flat vertical aquarium wall. each is 20 cm long from nose (closest to the glass) to tail (farthest from the glass), and each has its nose 10 cm from the glass. a) to the fish, how far does the cat's nose look to be from the glass? b) to the cat, how far does the fish's nose look to be from the glass? c) to the fish, how long does the cat look? d) to the cat, how long does the fish look? is thin enough to be ignored; you can treat this as an air/water interface. hint: to determine "where" a point appears to be, you must trace multiple rays emanating out from it, figure out how they refract, and then trace back to where the refracted rays seem to be diverging from.

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earthโs magnetic field, which is 0.50 g. is this value cause for worry?
