This diagram shows that Al can see the reflections of Ed and Fred in the mirror. Which two students can both see the reflections of Cy, Di, Ed and Fred? *
A)Bo and Cy
B)Cy and Di
C)Di and Ed
D)Ed and Fred

B) Cy and Di

Explanation:

Reflection is the process in which a ray of light is sent back along its path on hitting a plane surface. This ensure that the measure of angle of incidence is equal to that of reflection. Mirrors generally have a high reflecting capacity, thus its various applications.

From the diagram by ray construction,

i. Cy would see Cy, Di, Ed, and Fred

ii. Di would see Cy, Di, Ed, and Fred

Thus, it can be inferred that both Cy and Di would see the reflections of Cy, Di, Ed, and Fred from the mirror because of their locations.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
