As the summer intern for a company that manufactures nozzles for garden hoses, you are working on an adjustable hose nozzle project. Your design calls for a rotating head that has a number of cylindrical plugs that can be inserted into the hose opening. On a particular setting, the speed of the water passing around the plug is 5 times as large as the speed of the water in the hose. Determine the ratio of the plug radius (rplug) to the inside hose radius (rhose).

all of the answers are correct.

falsification is manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record. plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit.

are there answer choices to this question? this seems like a question where you have options to choose from.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
