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:
2
Explanation:
symbol of postassium is k and there is no symbol k. so i guess no2
<h2>Increase of reaction rate</h2>
Explanation:
- It is observed that when the concentration of acetylcholine remains constant in the reaction of an aqueous solution, the speed of the enzyme-catalyzed reaction or the formation of the product increases with increasing concentrations of substrate.
- The reaction rate is directly proportional to the concentration of acetylcholine.
- At very low concentrations of acetylcholine, there is a small increase in the concentration of the substrate which results in a large increase of the rate in reaction.
Answer:
<u>20.25 mL.</u>
Explanation:
The volume of base required for the titration can be derived by removing the base titrant volume from the volume at endpoint.
i.e Final volume - initial volume
= (22.08 - 1.83)mL
<u>= 20.25 mL.</u>
<em>(Repeat and average volume results for accuracy.)</em>
Answer:
Explanation:
Entropy is the measure of randomness of a system . When heat is added to a gas , gas molecules become more random and therefore , their entropy increases . Hence at higher temperature , entropy increases and randomness increases due to addition of heat .
Hence when a gas molecules become more ordered that means entropy decreases . Hence heat is withdrawn from the system . Hence temperature of the system is decreases .
In the given case , gas molecules are made more ordered that means their temperature is decreased to lower the entropy before they are exhausted .
