What is the difference between accuracy and precision, (1) first make a statement defining the difference between accuracy and precision, then (2) give an example of something that is accurate but imprecise and discuss why this is so; then (3) give an example of something that is precise but inaccurate and discuss why this is so; then (4) give an example that is both accurate and precise and discuss why this is so; then (5) give an example that is both inaccurate and imprecise and discuss why this is so; and (6) is there philosophy of logic which can reconcile and summarize these concepts?

probably not if net force is zero

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

its a 5.5 n

glad that

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.
