Answer:
Explanation:
initaial velocity=o m/s
final velocity =?
acceleration=4m/s
time=5 sec
acceleration=final velocity-initial velocity/time taken
4=final velocity-0/5
4*5=final velocity- 0
20+=final velocity
20m/s=final velocity
Answer: B. Show that light was composed of different colored rays
Explanation:
In the eighteenth century Isaac Newton found out that when a beam of light from the Sun, passes trhough a prism is decomposed in many different colors. He named this phenomenom as dispersion of light.
This phenomenom 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.
