Answer:
The (minimum) thickness of the oil slick is 325 nm.
Explanation:
Let the (minimum) thickness of the oil slick = 
Therefore:
2
= (
+
)*λ
/
(1)
similarly,
2
=(
)*λ

(2)
Thus, equation 1 = equation 2
(
+
*λ
= (

Where:
λ

Therefore:
=650/390=5/3
This shows that,
=2
=1
Thus, using equation 2

Answer:
Sound quality
Explanation:
Loudness refers to the property of sound that depends on the amplitude of the sound wave while pitch is the property of sound that depends on the frequency of the sound wave.
Now, when sounds have the same pitch and loudness, it means they possess the same natural frequency and also, they will have similar resonance and standing waves. Despite all these similarities, the quality of these sounds will tend to vary from one to another.
Answer:
The nature of the environment and the animal's interaction with it determines much of the character of the brain.
Explanation:
In fact, most of what we would use to describe ourselves to others reflects this sort of information storage. Much of this information is unique to the individual and hence may involve different mechanisms from those used for species-typical information storage.
