Answer:
A. velocity and wavelength
Explanation:
When a wave travels from one medium to another it undergoes refraction which results to the change in direction.
Refraction of a wave is one of the property of waves that occurs when a wave changes direction when it passes from one medium to another. This occurs as a result of bending of the wave which occurs since the mediums involved are of different density and refractive index.
Apart from the change in direction, refraction is accompanied by the change in wavelength of a wave and thus a change in speed.
This being a perfect collision means no energy is lost during the collision. Because this question asks for speed and not velocity, the speed will be the same because the final energy is the same. The speed after the collision would therefore be 1.27 m/s.

5 because there is 5 electrons. In order for an atom to be neutral it has to have the same amount of positive and negative charges.
Answer: A. AB + C → AC + B
Explanation:
A single displacement reaction is also known as single replacement reaction. A reaction in which an element replaces another element from the compound is known as single displacement reaction.
AB + C → AC + B
Here, element C replaces another element B from compound AB.
Thus, option A represents is a general equation for a single displacement reaction
Option B represents a double displacement reaction where one element of a compound replaces another element of another compound and vice-versa, option C is a synthesis reaction where two reactants or more combine to form one product. Option D is a decomposition reaction in which multiple products are formed from a single reactant.
