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!

Answer:</h3>
Concentration will be 0.1 M and not 0.050M
<h3>
Explanation:</h3>
This explains why the molarity is not 0.050 M but 0.1 M
Molarity is the concentration of a solution in moles per liter.
Therefore,
Molarity = moles ÷ Volume
In this case,
We have 1.34 g of CuCl₂ and a volume of 100 mL
To get the molarity we need to find the number of moles in 1.34 CuCl₂
Number of moles = Mass÷ molar mass
Molar mass of CuCl₂ = 134.45 g/mol
Therefore,
Moles of CuCl₂ = 1.34 g ÷ 134.45 g/mol
= 0.009965 moles
= 0.01 moles
Then we can calculate the molarity;
Molarity = Number of moles ÷ Volume
Volume of the solution is 100 mL or 0.1 L
Molarity = 0.01 moles ÷ 0.1 L
= 0.1 M
Therefore, the concentration of 1.34 g CuCl₂ in a volume of 100 mL is 0.1 M and not 0.050M.
Answer:
Atoms
Explanation:
Atoms are widely believed to be the most fundamental particle of matter and their basic building blocks. When atoms combines together, they form compounds. Molecules are another units of matter that are made up of tiny particles of atoms.
Answer:
893K=620 °C
Explanation:
PV=nRT
P=nRT/V
P= (1 mol* 0.0821* 298K)/15L P=1.63 atm
T=PV/nR
T=(1.63 atm*45 L)/(1 mol*0.0821)
T= 893K=620 °C
