Answer:
The wavelength of wave is 0.33 ×10²⁰ m.
Explanation:
Given data:
Frequency of wave = 9.12×10⁻¹² Hz
Wavelength of wave = ?
Solution:
Formula:
Speed of light = wavelength × frequency
c = λ × f
λ = c/f
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Now we will put the values in formula.
λ = 3×10⁸ m/s / 9.12×10⁻¹² Hz
Hz = s⁻¹
λ = 0.33 ×10²⁰ m
The wavelength of radiation is 0.33 ×10²⁰ m .
Answer:
Option c, Two atomic orbitals combine to form one molecular orbital
Explanation:
Molecular orbitals are formed by linear combination of atomic orbitals.
Some of the important facts of molecular orbital theories are as follows:
- No. of the molecular orbitals formed are equal to the no. of atomic orbitals participated.
- Half of the molecular orbitals are bonding molecular orbitals and half of the molecular orbitals are anti bonding molecular orbitals.
- Anti bonding molecular orbitals have energy higher than participating atomic orbitals.
- Bonding molecular orbitals have energy lower than participating atomic orbitals.
- Molecular orbitals are that region in the molecule where electrons are most likely to found.
So, among given, option c which is 'atomic orbitals combine to form one molecular orbital' is incorrect.
<h2>Hello!</h2>
The answer is:
The new volume is equal to 206.5 L.
<h2>Why?</h2>
To solve this problem, we need to assume that the pressure is constant, and use the Charle's Law equation, so, solving we have:

We are given:

Then, using the Charle's Law equation, we have:


Hence, we have that the new volume is equal to 206.5 L.
Have a nice day!
Ok, my favorite is turning lights off when not in use OR changing out old lightbulbs that are more efficient. :)
Answer:
Main job of golgi bodies is to sort and package proteins and other substances in a plant cell.
Explanation:
Golgi bodies are also called post office of the cell because it modify and distribute proteins for the cell. First, proteins are made in the organelle of the cell i. e. endoplasmic reticulum. From here, it is send to the Golgi apparatus for modification. Golgi bodies add some special structures with the protein and this protein leaves golgi bodies which is used by the cell where it is needed.
