Everything that Julia said is correct EXCEPT the words
"the Oxygen and Hydrogen separate". They do not.
The "particles" that she mentioned are water molecules,
each one composed of two Hydrogen atoms and one Oxygen
atom bonded together. THOSE are the particles that shift to be
farther apart, but the Hydrogen and Oxygen in each one remain
bonded together.

The velocity, frequency and wavelength of a wave are related by:
v = fλ
v = 32 x 0.5
v = 16 m/s
The answer is B.
Answer:
The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land.
Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. Now, recall that warmer air is lighter than cooler air.
Answer:
i. rubbing the material against a magnet
ii. placing the material in a magnetic field of opposite polarity
iii. placing the material near a strong magnet
Explanation:
Ferromagnetic materials are majorly metals which can be easily attracted by a magnet. ferromagnetic materials are made up of domains, behaves as minute pieces of magnet. They can be rearranged to align when under the influence of an external magnetic field.
The alignment of the domains in a ferromagnetic material can be caused by either of the following: rubbing the material against a magnet, placing the material in a magnetic field of opposite polarity, placing the material near a strong magnet.
Metallic bonding accounts<span> for many physical </span>properties of metals, such as strength, ductility, thermal and electrical resistivity and conductivity, opacity, and luster. I hope my answer has come to your help. God bless and have a nice day ahead!
