You come across an open container that is filled with two liquids. since the two liquids have different densities, there is a distinct separation between them. water, which has a density of ρw=1.00×103 kg/m3, fills the lower portion of the container to a depth of 0.203 m. the fluid that is floating on top of the water is 0.335 m deep. if the absolute pressure on the bottom of the container is 1.049×105 pa, what is the density, ρl, of the unknown fluid? the acceleration due to gravity is g=9.81 m/s2 and atmospheric pressure is p0=1.013×105 pa.

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.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.

conduct current i mean it makes sense
