Which best describes the relationship between the terms frequency, wavelength, and hertz?

Chemistry
1 answer:
Oksanka [162]3 years ago
5 0

Answer:

The correct answer is - Frequency is the number of wavelengths, which is measured in hertz.

Explanation:

Frequency is the number of waves that go through a fixed point at a particular time. Hertz is the SI unit for frequency which means that one hertz is equal to a unit number of waver passes in a unit time to a fixed point.

As the frequency of a wave increases which means the number of waves increases in the unit time, the shorter the wavelength will be.

a higher frequency wave has more energy than a lower frequency wave with the same amplitude.

Look back at your data and your regression equation. (Sample data is shown to the right, with x = pressure and y = volume.) Chec
VARVARA [1.3K]
The answer is: all true

<span>A. As the pressure of the gas increased, the volume of the gas decreased.
It is clear that if you compare the data on the left side. When the pressure increased the volume is decreased.

B. For all pairs of data of pressure and volume, P • V was appoximately the same.
The pressure is inversely related to the volume. You can take two data to prove it. Let use the first and second data
V * P= 1.03 * 50= 51.5
</span>V * P= <span>1.08 * 47.5= 51.3

C. For all pairs of data of pressure and volume, P • V mr001-1.jpg k for the same value k.
D. The regression equation was of the form V = kP–1 (which is the same as V = k/P).
The value of k can be expressed as k= P*V. If the equation is turned around, it could be expressed as V= k/P
The value of k is constant on different data, proved by the calculation on the second statement above. The value of k should be around 51.5

How many valence electrons are in an atom of strontium (Sr)? Consult the periodic table. A. 5 B. 2 C. 47.90 D. 22
Kaylis [27]

The smallest and the basic particle of a chemical element is said to be an atom. It is made up of three subatomic particles that is electrons, protons and neutrons.  The neutrons and protons are present in the nucleus of an atom whereas electrons are present in the orbits around the nucleus of the atom.  There are several shells in the orbital depending on the atomic number.  The electrons which are present in the outermost shell are said to be valence electrons.

They can be determined by the electronic configuration of the element.

The atomic number of strontium, Sr is 38. The electronic configuration of strontium, Sr is:

1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}

From the electronic configuration it is clear that the outermost shell of strontium, Sr is 5s. So, the number of valence electrons in strontium, Sr is 2.

Hence, there are 2 valence electrons in an atom of strontium (Sr).
