Answer:
A
Explanation:
According to Snell's law refractive index is the ratio of the sine of the angle of incidence to the normal to the barrier ( the normal is perpendicular to the surface of the barrier) to the ratio of the sine of refraction ( the angle of emergence from the second barrier) and also equals the ratio of the speed of light in the first barrier to the ratio of the speed of light in the second barrier.
Since there is no change in the direction of the propagation of light then the two materials must have matching indexes of refraction.
Answer:
c. The less massive object will have less momentum if the velocities are the same.
Explanation:
p = mv
If the velocities are the same, p ∝ m, so the less massive object will have less momentum.
a. is wrong. If the masses are equal, p ∝ v, so the object with the higher velocity will have the greater momentum.
b. is wrong. If an object has both more mass and a greater velocity, it will have the greater momentum.
d. is wrong. If the velocities are the same, the more massive object will have more momentum.
Answer:
Explanation:
strike-slip, normal and thrust
mark her as brainiest, :) I don't need it :P
I’m not sure I’m just gonna assume that the flashlight closed too the wall is gonna be brighter because most of it’s light is directed on the wall rather then the one further back is kinda pointed everyone else & I think it relates to stars as if the brighter the star the closed it is to earth ?
