Answer:
I think is the second one
Answer:True.
As you increase the wavelength the frequency decreases.
Explanation:
The wavelength of a wave is the distance(in meters) between the two consecutive crest and trough of a wave. The S.I unit of the wavelength is meter.
The frequency of a wave is the number of complete wave cycle passing a particular point per second. The S.I unit of the frequency is Hertz.
Wave's frequency and wavelength are related to each other as
Frequency = 1 / Wavelength
As the Frequency is inversely proportional to the wavelength of a wave so as the frequency will increase the wavelength of the wave will decrease and vise-versa.
So, its true that As we increase the wavelength the frequency decreases.
Answer:
H must pair with Fluorine, Oxygen, or Nitrogen
Explanation:
water has polar covalent bonds, the intermolecular forces are hydrogen bonds, London and Dipole forces
As the H bond of the butanol is more effective and strong than Van der Waals forces of the ether the surface tension in alcohol is more intensive.
So the correct answer is e)
