Discussion topican enormous amount of electricity is created atpower-generating stations and sent across thecountry through wires that carry high voltages. appliances, power lines, airport and militaryradars, substations, transformers, computers, andother equipment that carries or uses electricity allgenerate electromagnetic fields. many questions have been raised about howelectromagnetic fields affect our bodies. do theypose a public health risk? perform an internetsearch to find information about the effects ofelectromagnetic fields on public health. then, discuss the pros and cons of using equipment thatproduces an electromagnetic field.

Which fators influence ocean currents

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?
