You're in luck ! Momentum is the product of (mass) times (velocity).
So if you're given mass and velocity, simply multiply them, and voila,
you have the momentum.
Im going to guess on this one, and say that it is chemical.

Explanation:
Refraction is a phenomenon in which a wave (the light in this case) bends or changes its direction <u>when passing through a medium with a refractive index different from the other medium.</u> Where the Refractive index is a number that describes how fast light propagates through a medium or material.
According to this, if we observe the rays A an D passing throgh the biconcave lens, we will have two mediums:
1) The air
2)The material of the biconcave lens
This two mediums have different refractive indexes, hence the rays will change the direction.
-For the incident ray A, the corresponding refractive ray is B, because is the ray that bends after passing throgh the lens
-For the incident ray D, the refracted ray is E following the same principle.
Answer: Momentum applies to objects in motion and is the product of mass and velocity. It is not the energy, but the variables are the same. By contrast, "moment" is an expression of the "rotational force" caused by a force acting at some distance from a fulcrum.
A is the correct answer.
please vote my answer branliest! Thanks.
