Answer:
The correct answers are "They travel slower than P waves", "They result in much ground motion" and " They are produced by P and S waves".
Explanation:
A surface wave can travel through the existing interface between Earth and air, as well as between Earth and water. A clear example of this type of waves are Love and Rayleigh waves. They travel slower than primary waves, produce large movements in the ground and are produced by primary and secondary waves.
Have a nice day!

Explanation:
Hello!
In this case, since vaporization is the processes by which a liquid goes to the gas phase, fusion by which a solid goes to liquid and deposition by which a gas goes to solid; we infer that the following set up relates the enthalpies associated to each process:

Because deposition goes from a state with more energy to a state with less energy, therefore it is negative; in such a way, by plugging in we obtain:

Answer:
Properties of Metals:
- Shiny
-Malleable
-Good Conductors of electric current
- Good conductors of heat
Properties of Non-metals:
- Dull
- Not Malleable
- Bad conductors of electric current but good electric insulators
- Poor conductors of heat
Note: The first dash for the Properties of metals goes with the first dash of Properties of Non-metals and so on.
Answer:

Explanation:
When water changes from ice (solid) to water (liquid), it is melting or fusion. Therefore, we can use the following formula to find energy:

where <em>q</em> is the energy, <em>m </em>is the mass, and <em>Hf</em> is the heat of fusion.
1. Define Values
The mass is 150 grams. The heat of fusion for water is 334 Joules per gram.

2. Calculate Energy
Substitute the values into the formula.

Multiply. Note that the grams (g) will cancel each other out and leave Joules as our units.


3. Convert Units
We found the answer in joules, but the question asks for kilojoules, so we must convert.
There are 1000 Joules in 1 kilojoule. Therefore, we can divide the joules calculated by 1000.



<u>50.1 kilojoules </u>are needed to change 150 grams of ice to water.
