Violet
Explanation:
1. As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
2. Isaac Newton's experiment in 1665 showed that a prism bends visible light andthat each color refracts at a slightly different angle depending on the wavelength of the color.

Answer:
Option e
Explanation:
The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe by a force pointing in a straight line between the centers-of-mass of both points, and this force is proportional to the masses of the objects and inversely proportional to their separation This attractive force always points inward, from one point to the other. The Law applies to all objects with masses, big or small. Two big objects can be considered as point-like masses, if the distance between them is very large compared to their sizes or if they are spherically symmetric. For these cases the mass of each object can be represented as a point mass located at its center-of-mass.
The same force is applied to both the balls.
Answer: 1 kilometer = 1,000 meters
Explanation:
<u>The decimal metric system is the predecessor of the International System of Units (SI)</u> and consists of a system in which the multiples and submultiples of the unit of measure are related to each other by multiples or submultiples of ten (10).
It should be noted that this system was created to be neutral and that it could be easily used, understood and adopted by all countries. However, so far only the United States, Myanmar (Burma) and Liberia have retained their traditional units of measurement instead of the Decimal Metric System, which was then replaced by the current SI.
In this sense, two main basic units of this system are the meter (to measure length) and the gram (to measure mass). In the specific case of the meter there are submultiples of the same nature that follow a decimal scale, for example:

Therefore, among the given options, the one that fulfills the explained conditions is 1 kilometer = 1,000 meters
The other options do not follow a decimal system.
