Answer:
smaller one
Explanation:
even though he is moving quicker doesn't mean he will be packing more force in the collision
Answer:
true.
Explanation:
z-score gives an idea of how far the value of data is from the mean point. Basically is the measure of a standard deviation below or above the mean.
More the deviation of the data from the mean more is the standard deviation.
Z-score or value is calculated by the expression given below:

x is the value
μ is the mean
σ is the standard deviation
Hence, the statement given is true.
To solve this problem we will apply the concepts related to the principle of destructive and constructive interference. Mathematically this expression can be given as

Here,
n = Index of refraction
t = Thickness
m = Order of the reflection
= Wavelength
We have all of this values, therefore replacing,

Therefore the thickness of the oil slick is 233nm
