<span>Two sound waves of equal amplitude interfere so that the compression of one wave falls on the rarefaction of the other. The statement which is true is that A. no sound is heard.
These waves interfere, which means that their equal amplitudes match and thus cancel each other out, which is why there is no sound.

Formulas you need for this problem:
F= mass•acceleration
KE= mass•velocity^/2
Acceleration= final velocity-intial velocity/time
time= distance/speed
t= 97.5\10= 9.75 seconds
Acc= 10-20/9.75= -1.03 m/s/s
These are the answers :)
F=650•-1.03= -669.5N
KE= 650•100/2= 32,500J or 32.5KJ
Inorganic chemical compounds
Explanation:
Inorganic chemical compounds employ the use of oxidation numbers of atoms to write their chemical formula.
- The oxidation number is the formal charge assigned assigned to an atom present in a molecule or formula unit or ion based on some rules.
- Knowledge of this number is used in writing the formulae of inorganic compounds.
- These compounds forms by the exchange of certain small whole numbers by atoms or groups of atoms.
- The combining power usually correspond to the number of electrons usually lost or gained or shared by atoms of elements during chemical combinations or the number of positive or negative charges carried by ions.
For example:
A B
combining power(Valency): X Y
Exchange of valencies Y X
Molecular formula of compound A
Bₓ

Answer:
They would likely do a whole series of dynamic stretches
Explanation:
It would include warming up the body and then dynamically stretching the lower body, and some upper body as well. This isn't a question with one specific answer
The answer is true, the thrower has to be outside of the field
