Answer from: jennsou

The choices for this question are needed so as to determine which really is suitable for using the meter units. These are as follows:

a. Measuring a wingspan of a certain insect
b. measuring the height of a specific building.
c. measuring the length of a single ant.
d. measuring the distance between two cities

I think the correct answer would be B. The SI unit of measure for length the meter would be most appropriate when measuring the height of a specific building. Using it for the measurement of the wingspan of an insect and the length of an ant would still be acceptable but these subjects are very small and it would be best to use a smaller scale like millimeters or centimeters. For the measurement of the distance between cities, it would be best to use the units of miles as it has a bigger scale than a meter.

Answer from: greenbyron88

It would be seeing the height of a building

Explanation:

Measuring a wingspand or an ant or any insects are to small. So,doing a building is bigger and wider then a insect.

v 154.9= 0.9 length length s little over 154.9cm

Answer from: Quest

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.
