A block is being pulled upward along an inclined surface at a constant speed. Which of the following statements is correct? Grou
p of answer choices The net force on the block points upward along the inclined surface. The net force on the block is zero. The net force on the block is larger than the magnitude of the weight of the block. The net force on the block is smaller than the magnitude of the weight of the block but greater than zero.
The relative refractive index ₁n₂ between the two medium can be as follows;
Therefore, given that the speed of light in medium 1 is constant and the speed of light on medium 2 is also constant, the relative refractive index ₁n₂ = c₁/c₂ is always constant.
