The three phases of matter differ in properties just because of the proximity of their molecules. The solid phase is the most organized of all. Its atoms are compactly arranged together and has the strongest intermolecular forces to keep them together. This is why they have a definite shape and volume. The liquid phase have molecules that are far away from each other, but not as far as that of the gas phase. The liquid and gas phases can be lumped into one group called fluids because they have the same property - they take the shape and volume of their container.

Answer:
a
The effect of a change in the price of a new pair of headphones on the equilibrium price of replacement tips ( dp/dpN) is
b
The value of Q and p at equilibruim is
and
5
The consumer surplus is
The producer surplus is
Explanation:
From the question we are told that
The inverse market demand is
The inverse supply function is
a
The effect of change in the price is mathematically given as
Now differntiating the inverse market demand function with respect to
We get that
b
We are told that $30
Therefore the inverse market demand becomes
At equilibrium
So we have
Where is the quantity at equilibrium
Substituting the value of Q into the equation for the inverse market demand function
5
Looking at the equation for we see that
For Q = 0
And for Q = 250
Hence the consumer surplus is mathematically evaluated as
Substituting value
And
The producer surplus is mathematically evaluated as
