Number one a and b are automatically out if you decrease the pitch or frequency you wont hear it louder it does not add up ok?
number 2 the answer would be C the higher the frequency the higher the pitch the lower the frequency the lower the pitch this just comes back to common sense. for example you cant decrease the frequency and than expect a louder pitch its like saying I am going to smash the key on this piano with all my strength and it will make a small very low pitch sound you get what I mean so your answer would indeed be C.
Answer:
The mass is 
Explanation:
Generally from Newton law for the first block
=> 
For the second block the force is 
and the acceleration is 
So from Newton law
=> 
substituting for a
=> 
=>
The answer is B. Domain
When the atoms point to the same direction and aligned with one another, It will form a magnetic material in which magnetization is in a uniform direction
This alignment usually happens stimunaleously due to exchange interaction that caused by a response to an external field.
