Answer:
Hi
The water molecule is composed of three atoms: an oxygen atom and two hydrogen atoms. Very strong electromagnetic forces hold the atoms inside the molecule.
A parallel electromagnetic attraction exists between the molecules individually. Water molecules are constantly moving and continuously form and break bonds with other molecules. As the temperature rises, the molecules move faster and the bonds weaken, changing their state to gas. This is called the boiling point. At this stage, the distance between water molecules is large and intermolecular bonds are almost non-existent.

Explanation:
Answer:
v = 450 m/s
Explanation:
Given data:
Frequency = 75 Hz
Wavelength = 6 m
Velocity = ?
Solution:
Velocity is the product of frequency and wavelength.
v = f × λ
v = 75 Hz × 6 m
Hz = s⁻¹
v = 75 s⁻¹ × 6 m
v = 450 m/s
