Answer:
Q = 7272 Kilojoules.
Explanation:
<u>Given the following data;</u>
Mass = 2.0*101kg = 202kg
Initial temperature, T1 = 10°C
Final temperature, T2 = 90°C
We know that the specific heat capacity of iron = 450J/kg°C
*To find the quantity of heat*
Heat capacity is given by the formula;
Where;
- Q represents the heat capacity or quantity of heat.
- m represents the mass of an object.
- c represents the specific heat capacity of water.
- dt represents the change in temperature.
dt = T2 - T1
dt = 90 - 10
dt = 80°C
Substituting the values into the equation, we have;
Q = 7272KJ or 7272000 Joules.

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
