Answer:
1. Amplitude Modulation
Explanation:
AM is an acronym for Amplitude Modulation and it's refers to a process that is typically used for coding sounds such as voices and music for transmission from one point to another.
On the other hand, FM is an acronym for frequency modulation used for the propagation and transmission of sound waves.
Basically, the two forms of modulation are used for broadcasting in radio transmission.
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.
Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.
A. I looked it up and it should be somewhere around A
Answer:
The height of the pyramid is approximately 104 Ft. See the graphic attached.
Explanation:
First, you have to plot to realize that you have two rectangle triangles, formed by the different elevation points of view. From there you can have a system of two equations, with two unknown values.
Equation (1)
Equation (2)
![tan 18^{o}10'=\frac{Ph}{x+183} \\\\Ph=[tan 18^{o}10'][x+183]=[0.3281][x+183]](https://tex.z-dn.net/?f=tan%2018%5E%7Bo%7D10%27%3D%5Cfrac%7BPh%7D%7Bx%2B183%7D%20%5C%5C%5C%5CPh%3D%5Btan%2018%5E%7Bo%7D10%27%5D%5Bx%2B183%5D%3D%5B0.3281%5D%5Bx%2B183%5D)
Matching (1) and (2)
replacing x value in (1)
The oxygen is the Solute, since this is smaller in quantity.
The Nitrogen is the Solvent, since this is more in quantity.
The air is the Solution, this is the mixture itself.
