Answer:
a) the light is close to normal therefore the reference incidence of medium 1 is less than medium n2 where the ray is transmitted.
b) The ray is far from normal in this case the refractive index of medium 1 is greater than index of medium 2
Explanation:
The expression for the angle of refraction is
n₁ sin θ₁ = n₂ sin θ₂
refractive index n₁ is for incident light and n₂ is for transmitted light.
We have two cases
a) the light is close to normal therefore the reference incidence of medium 1 is less than medium n2 where the ray is transmitted.
b) The ray is far from normal in this case the refractive index of medium 1 is greater than index of medium 2
Answer:
Explanation:
In a completely inelastic collision the momentum P is conserved, so can be expressed as:
As P is defined as:
Replacing:
(Eq. 1)
As the problem says that the two cars have the same mass:
And in a completely inelastic collision the velocities after the collision are equal, so:
So replacing in Eq. 1:
Solving for :
And replacing the values for the velocity:
Just plug in the values of v and t...that will give the magnitude of average acceleration
