Answer:
Place theory.
Explanation:
Place theory explains the different perception of sounds on the basis of the different sound waves. This theory helps to explain how the individual can differentiate different pitch sounds.
The different sound frequency causes vibration at the basilar membrane of the cochlea. The different areas of cochlear membrane gets activated by the different frequency of sound. These different vibration enable to distinguish between high pitch and low pitch sounds.
Thus, the answer is place theory.
Its not really definable. Say, you can have a full moon on the last day of November, and have the waning phases throughout the first half. Or you can have a new moon on the last day of December, and have the waxing phases during the first half of the month.

I do believe it is the third choice
It's to determine if there is a charge on an object/body or not and what kind of charge as well. Hope this can help!
Answer:
The final kinetic energy is 
Explanation:
From the question we are told that
The electric field is 
The charge on the object is 
The mass of the object is 
The distance moved by the object is 
The workdone on the object by the fields is mathematically represented as
![W = [qE + mg]d](https://tex.z-dn.net/?f=W%20%3D%20%20%5BqE%20%2B%20mg%5Dd)
Now this workdone is equivalent to the final kinetic energy so
![K = W = [qE + mg]d](https://tex.z-dn.net/?f=K%20%3D%20W%20%3D%20%20%5BqE%20%2B%20mg%5Dd)
substituting values
![K = W = [4.5*10^{-3 } *100 + 0.68 * 9.8]* 1](https://tex.z-dn.net/?f=K%20%3D%20W%20%3D%20%20%5B4.5%2A10%5E%7B-3%20%20%7D%20%2A100%20%20%2B%200.68%20%2A%209.8%5D%2A%201)
