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.

As a system increases in volume, it absorbs 59.0 J of energy in the form of heat from the surroundings. The piston is working ag
Zepler [3.9K]

Answer:

The initial volume of the system is 2.7 L

Explanation:

The change in internal energy is given by;

ΔU = Q - W

where;

Q is the heat absorb from the surrounding

W is the work done by the system

Given;

ΔU  = -107.6 J

Q = 59 J

W = ?

W = Q- ΔU

W = 59J - (-107.6)

W = 166.6 J

Work done is given by;

W = PΔV

W = P(V₂ - V₁)

101.325 Joules = 1 L.atm

166.6 Joules  = ?

= 1.644 L.atm

1.644 L.atm = 0.543 atm(57.7L - V₁)

57.7L - V₁ = (1.644 L.atm) / (0.543 atm)

57.7L - V₁ = 3.0 L

V₁ = 57.7L - 3.0 L

V₁ = 2.7 L

Therefore, the initial volume of the system is 2.7 L

If there are 1,600 meters in a mile, find the speed of sound in this experiment in units of "miles / hour"
atroni [7]

Answer:

v = 771.75 mile / h

Explanation:

The speed of sound is v = 343 m / s  at T= 20C

the transformation ratios are

     1 mile = 1600 m

     1 h = 3600 s

Let's reduce

    v = 343 m / s (1 mile / 1600 m) (3600 s / 1 h)

    v = 771.75 mile / h
