(Read the table and answer the following question) SN (Medium) ) / (Weight of
substance in
the medium)
1)
X / 1ON
2)
Y / 16N
3)
Z / 12N
(a) Which might be water, air and salt solution?

(b)
If the weight of 1 kg mass in air is 9.8 N, then what will be the mass of the stone in salt solution and water?

(c) Find the upthrust experienced by the stone in salty water​

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
