Doğrusal bir yörüngede hızını değiştirmeden hareket eden aracın hareketine ne ad verilir? a) Düzgün doğrusal hareket b) Düzgün yavaşlayan hareket c) Düzgün hızlanan hareket d) Sabit ivmeli hareket e) Değişken ivmeli hareket

thermal energy is the answer

answer: a. same unit

explanation:

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.
