Answer: dispersion</h2>
The dispersion of light occurs when a beam of white light (which is compound of many wavelengths or "colors") is refracted (the different rays of light are diverted depending on their wavelengths) in some medium, leaving their constituent colors separated.
The best known case is when a beam of white light from the sun passes through a prism, thus obtaining rays of different colors like those of the rainbow.
This phenomenom was named by Isaac Newton in the eighteenth century, who performed the experiment explained above.
Hence, the correct option is C.
Momentum = mass • velocity
M = m • v
Speed is a scalar quantity
Velocity is a vector quantity
That is truly the only difference

Answer:
t=4.86s
Explanation:
To find the wavelength you use the following formula:

v: speed of sound = 343m/s
f: frequency = 400Hz
λ: wavelength of the sound
By doing λ the subject of the formula and replacing the values of f and v you obtain:

Now, to calculate the time that sound takes to reach the last row you use:

t: time
d: distance to the last row = 1947m

hence, the time is 4.86s
D is the best answer. In many physics problems we treat an extended object as if it were a point with the same mass located at the center of mass.
