Suppose three mass measurements are taken as follows: 210 ± 15 kg, 28 ± 5 kg, and 33 ± 6 kg. find the sum of the masses, mm.
on a separate piece of paper, write the equation for the sum of masses: m = m1 + m2 + m3. find the value of m, δm, and mm. show your work. note: refer to figure 10 to determine the appropriate equation for calculating δm.
write your name and date on the paper. take a clear photograph of your work and upload the image into photo 3.
record the value of mm in data table 1.

representative si the final answer! : )

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.
