Of ice b Calculate the final temperature of mixture on mixing 10gm of ice at at - 20degree Celsius with 100ml of water' at 60ºC . Use specific latent heat of fusion of ice heat capacity of ice 2100 X10S Ilkgk Capacity of water 4100 J/KQK. 3.36 X 105 J/kg J/kg specific and specifice heat

reserve is the answer

because growing process had stoped after 4-5 year

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.
