A beam of light passes from one medium into the air (second medium). Angle1 (angle of incidence) is 30°. Angle 2 (angle of refraction) is 48°. Calculate the refractive index of the original medium. (ROUND TO THE NEAREST HUNDREDTH)

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
