<h2>
Cohesion </h2>
Is the attraction that molecules have for others of their same type.
<h2>
Adhesion </h2>
Is the attraction that molecules have for others of different type by intermolecular forces.
A good example of both is water that can stick to itself through hydrogen bonds (cohesion) and can also stick to a glass due to adhesion.
So, while Cohesion is the force of attraction between adjacent particles within the same body, Adhesion is the interaction between the surfaces of different bodies.
B if not please comment back .
Answer:
Scalar quantity is the Physical quantity expresed only by their magnitude.
Explanation:
Formula for path difference is as follows.
x = 2tn
and, refractive index (n) = 
Thickness is calculated as follows.
Thickness (t) = 
Area = 
= 
= 
=
m
Now, the refractive index will be calculated as follows.
For drop, n = 
For B drop, n = 
So, n = 
= 
= 1.5
Thus, we can conclude that index of refraction of the oil is 1.5.
