Identify which phase of matter would transmit light waves the fastest, and why? a) the gas would transmit the fastest because the particles move the fastest. b) the solid would transmit the fastest because the particles are closest together. c) the liquid would transmit the fastest because the particles are the most freely moving. d) the gas would transmit the fastest because there are the fewest particles to interfere with the waves.

The metric unit of electrical power is the watt volt ampere ohm

When you turn on a battery-operated device, an electrical circuit is

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?
