How does amplitude affect the wavelength?<br>​
docker41 [41]

Answer:

Amplitude does not effect the wavelength in linear system.

Explanation:

Amplitude:

It is the measure of height from peak to trough.

Wavelength:

It is measure of length from peak to peak.

There is no relation between the amplitude and wavelength but if the system will no more linear then high amplitude can cause the distortion in wave if more frequencies are present. However frequency and wavelength can be related. The wave with higher frequency have shorter wavelength and vise versa.

Frequency:

It is the number of waves passing through a given point in a given time period. It is measure in Hz or s⁻¹

How does electronegativity affect the polarity of the bond between two atoms?
Fantom [35]
It can allow the molecule (like water) to be polar because it has a negative and positive side to it (oxygen holds the negatives tight causing the hydrogens to be positive).

If the fugacity of a pure component at the conditions of an ideal solution is 40 bar and its mole fraction is 0.4, what is its f
yaroslaw [1]

Answer : The fugacity in the solution is, 16 bar.

Explanation : Given,

Fugacity of a pure component = 40 bar

Mole fraction of component  = 0.4

Lewis-Randall rule : It states that in an ideal solution, the fugacity of a component is directly proportional to the mole fraction of the component in the solution.

Now we have to calculate the fugacity in the solution.

Formula used :

f_i=X_i\times f_i^o

where,

f_i = fugacity in the solution

f_i^o = fugacity of a pure component

X_1 = mole fraction of component

Now put all the give values in the above formula, we get:

f_i=0.4\times 40\text{ bar}

f_i=16\text{ bar}

Therefore, the fugacity in the solution is, 16 bar.
