Answer:
The speed of the wave at the given wavelength and frequency is 60 m/s.
The given parameters;
wavelength of the wave, λ = 0.5 m
frequency of the wave, f = 120 Hz
The speed of the wave is calculated by applying general wave equation as shown below;
v = fλ
where;
v is the speed of the wave
v = 120 x 0.5
v = 60 m/s
Thus, the speed of the wave at the given wavelength and frequency is 60 m/s.
A phenomenon in which anyone can be dismissed at any time and for any reason at all, or even for no reason simply means employment at will.
<h3>Who is an employee?</h3>
An employee refers to an individual who is employed by an employer of labor in a business firm, so as to perform specific tasks, duties or functions on a daily basis, usually on a full-time or contract basis.

Answer:
the first 3
Explanation:
I thought about it and memorizing isn't really critical
The mole fraction of the non-volatile solute in the solution is 0.13.
<h3>Mole fraction of solute </h3>
Using law of vapor pressure formula
Mole fraction of the non-volatile solute=Vapor pressure of the pure acetone-Vapor pressure of the solution /Vapor pressure of the pure acetone
Where:
Vapor pressure of the pure solvent (acetone) =266 torr
Vapor pressure of the solution =232torr
Mole fraction of solute = ?
Let plug in the formula
Mole fraction of the non-volatile solute=266-232/266
Mole fraction of the non-volatile solute=34/266
Mole fraction of the non-volatile solute=0.127
Mole fraction of the non-volatile solute=0.13 (Approximately)
Inconclusion the mole fraction of the non-volatile solute in the solution is 0.13.
