I would go with C. H2 and O
I hope this helps you :)
Lead is more ductile than iron. The correct option is A. Lead is more ductile than iron
<h3>Young's modulus </h3>
From the question, we are to determine the statement which is true
First, we will define the term <em>Young's modulus </em>
<em>Young's modulus</em> is a measure of the stiffness of an elastic material. It is also given as the ratio of <u>stress </u>to <u>strain</u>. That is,
The greater the modulus, the stiffer the material.
Materials with low Young's modulus tend to be <u>ductile </u>and materials with high Young's modulus tend to be <u>brittle</u>
Since the Young's modulus value for iron is higher than that of lead, then iron is <em>stiffer </em>than lead.
Thus, lead is more ductile than iron. The correct option is A. Lead is more ductile than iron

Explanation:
At each reflecting surface (benzene and glass) there will be 180 degree phase change.
Now, for constructive interference the optical path in benzene is .
Formula to calculate thickness of a benzene thin film is as follows.
Optical path length through benzene () =
Hence, substituting the given values into the above formula as follows.
Optical path length through benzene =
d =
=
= (as 1 nm =
= 204.9 m
Thus, we can conclude that minimum thickness of benzene is 204.9 m.
i’m pretty sure it is B i took thsi a while ago
