Answer: Because of the polarity of water molecules
Molecular <u>cohesion</u> is the attraction that molecules have for others of their same type. Depending on the intensity of this attraction, a substance is in a solid, liquid or gaseous state.
In this sense, water (
) can stick to itself through hydrogen bonds, because a water molecule consists of 2 hydrogen atoms attached to 1 oxygen atom.
The oxygen atom tends to monopolize more electrons and keeps them away from hydrogen. Then, it can be said that a water molecule will have a negative side (oxygen) and a positive side (hydrogen).
<u>Thanks to this polarity</u>, water molecules can stick together with the formation of<u> hydrogen bonds</u> to attract a partial positive charge of hydrogen and a more electronegative atom, such as oxygen.
False. That description fits the wave's 'frequency'.
It has nothing to do with refraction.
Answer:
parasites are creatures the gain benefit off of other animals usually harming them eg:ticks on dogs
Answer:
a) The total force is 4659.8 N
b) The gauge pressure is 50764 Pa
Explanation:
Given:
Pressure inside = 0
Patm = pressure outside = 1.013x10⁵Pa
Pressure difference = ΔP = 1.013x10⁵ - 0 = 1.013x10⁵Pa
a) The area is equal:

The force is:

b) The gauge pressure at the bottom is equal:

Where:
ρ = density = 1000 kg/m³
h = 17 ft = 5.18 m
Replacing:
