______ is the maximum distance the particles of the medium move from their resting positions when a wave passes through.
UkoKoshka [18]

Answer:

Amplitude

Explanation:

A wave is a periodic oscillation that carries energy, but not matter, through space or through a medium.

A wave is characterized by the fact that the particles in the medium oscillate around a fixed point, but there is no overall movement of particles in the direction of the wave (this means, only energy is transferred, while matter is not transferred).

A wave is also characterized by several properties, namely:

Amplitude: it is the maximum distance the particles of the medium move from their resting positions

Frequency: the number of oscillations of a certain particle per second

Wavelenght: the distance between two points of the wave that have same shape

Period: the time it takes for one particle of the wave to complete one oscillation

So, the answer is

Amplitude

The angle of elevation to the top of a very tall Building is found to be 6° from the ground at a distance of 1 mi from the base
DanielleElmas [232]

Answer:

555

Explanation:

The scenario is shown in the image attached below. A Right Angled Triangle is formed. We have an angle of 6 degrees, the side adjacent to angle which measures 1 mile and we need to find the side opposite to the angle.

Since 1 mile = 5280 feet, the side adjacent to the angle has a measure of 5280 feet.

Tangent ratio relates the opposite and adjacent side by following formula:

tan(\theta)=\frac{Opposite}{Adjacent}

Using the given values, we get:

tan(6)=\frac{x}{5280}\\\\ x=tan(6) \times 5280\\\\ x = 555

Thus, rounded to nearest foot, the height of the building is 555 feet
