Answer:
230hz
Explanation:
Hello,
To solve this question, we gave to use the relationship between velocity-frequency-wavelength to find the frequency in this question.
V = Fλ
V = velocity or speed of the wave
F = frequency of the wave
λ = wavelength of the wave
Data;
V = 414m/s
λ = 1.8m
f = ?
V = fλ
f = v/λ
f = 414/1.8
f = 230hz
The frequency of the wave is 230hz

Answer:
Water's boiling point is higher than acetone's one due to the stronger intermolecular forces it has in liquid phase.
Explanation:
Hello.
In this case, since no options are given we can infer from the statement that due to water's higher boiling point than acetone we can conclude that when they are in liquid state, water has stronger intermolecular forces which allow its particles to be held in a stronger way in comparison to the acetone's molecules, for that reason, more energy will be required in order to separate them and promote the boiling process, which is attained via increasing the temperature. Besides, less energy will be required for the separation of the acetone's molecules in order to boil it when liquid, therefore, a lower temperature is required.
In such a way, we can sum up that water's boiling point is higher than acetone's one due to the stronger intermolecular forces it has in liquid phase.
Regards.
