4. Mineral used as fuel.

NemiM [27]

Answer:

The mineral fuels—coal, petroleum, and natural gas—may be described as a special type of economic deposit. Geochemically they represent the concentration of carbon and hydrogen by processes that were initially biological in nature.

What is the relationship between kinetic energy and velocity ?

Harlamova29_29 [7]

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

A. Match the term with its definition. (1 point)

Assoli18 [71]

Taking into account the definition of wavelength, frecuency and propagation speed:

Frequency: The number of waves passing a point in 1 second.
Wavelength: The distance between two adjacent wave peaks.
Velocity: The direction and speed at which a wave is traveling.

The equation that illustrates the relationship between wave velocity, frequency, and wavelength is v = f×λ.

<h3>Wavelength</h3>

Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

<h3>Frequency</h3>

On the other side, frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

<h3>Propagation speed or velocity</h3>

Finally, the propagation speed is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement.

The propagation speed relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:

v = f×λ

All electromagnetic waves propagate in a vacuum at a constant speed of 2,998 x 10⁸ m / s, the speed of light.

Therefore, the previous expression establishes an inversely proportional relationship between the frequency and the wavelength: The higher the frequency, the lower the wavelength and when the frequency is lower, the greater the wavelength.

<h3>Summary</h3>

In summary, the definition of frequency, wavelength and velocity are:

Frequency: The number of waves passing a point in 1 second.
Wavelength: The distance between two adjacent wave peaks.
Velocity: The direction and speed at which a wave is traveling.

Finally, the equation that illustrates the relationship between wave velocity, frequency, and wavelength is v = f×λ.

Properties of iron, barium, and phosphorus. Explain why nails are made of iron but they are never made of barium or phosphorus.

bearhunter [10]

Nails are made up of iron not of phosphorus and barium.

As both phosphorous and barium are relatively weaker than iron ,phosphorus breaks easily and barium is also fairly weak. Iron nails are already also not that strong, but their weight and strength are sufficient.

So the nails are made up of iron.
