Asphere 5 cm in diameter has a small scratch on its surface. when the scratch is viewed through the glass from a position directly opposite, where does the scratch appear and what is its magnification? assume n = 1.5 for the glass.

Answer

given,

diameter of sphere = 5 cm

radius of sphere = -2.5 cm

refractive index for glass n₁ = 1.5

refractive index for air n₂ = 1

magnification of the glass = ?

now,

                  S' = - 10 cm

magnification

 m = + 3

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
