Answer:
η₁ = 2.6
Explanation:
Here, we will use snell's law to calculate the refractive of the substance:
where,
η₁ = refractive index of first substance = ?
η₂ = refractive index of second substance = 1.5
θ₁ = angle of incidence = 30°
θ₂ = angle of refraction = 60°
Therefore,
<u>η₁ = 2.6</u>
Speed = distance / time = 55 / 0.75 = 73.3 miles per hour.
Venus moves faster than earth because it move with a higher speed as compared to earth.
<h3>Is Venus move faster than earth?</h3>
Venus move with the speed of 35.02 km/s while on the other hand, the earth moves with the speed of 29.78 km/s. So due to more speed of Venus, the Venus completes its revolution earlier than earth.
So we can conclude that Venus moves faster than earth because it move with a higher speed as compared to earth.
