Consider the general demand function:
Q1 = 8,000 - 16P + 0.75M + 30PR
a. Derive the equation for the demand function when M = $30,000 and P. = $50.
b. Interpret the intercept and slope parameters of the demand function derived in
part a.
C.
Sketch a graph of the demand function in part a. Where does the demand function
intersect the quantity-demanded axis? Where does it intersect the price axis?
d. Using the demand function from part a, calculate the quantity demanded when the
price of the good is $1,000 and when the price is $1,500.
e.
Derive the inverse of the demand function in part a. Using the inverse demand
function, calculate the demand price for 24,000 units of the good. Give an
interpretation of this demand price.
Suppose the Egyptian government requires cigarette smokers to pay tax on each pack of cigarettes. Draw a supply-and-demand diagram of the market for cigarettes with and without the tax. Show the price paid by consumers, the price received by producers, and the quantity of cigarettes sold before and after-tax. What is the difference between the price paid by consumers and the price received by producers? Has the quantity of cigarettes sold increased or decreased?
5. An electron has a kinetic energy of 6.4 X 10-19 J. What is this energy in electron volts?
6. Two metallic plates are 0.04 m apart and the potential difference between them is 50 V. Between the two equipotential surfaces, there is a potential difference of 2.5 V. Find the spacing in this part of the field between two metal plates.
3. Four point charges are placed at the four corners of a square that is 30 cm on each side. Two of the 4 charges are +2μC and two are -2μC. Find the potential at the center of the square.
4. The potential difference between two parallel plates of a condenser that are 4 mm apart is 800 V. What is the potential gradient?
A. If you do 12 J of work to push 0.001 C of charge from point A to point B in an electric field, what is the potential difference between points A and B?

The FizzBuzz Game
by CodeChum Admin
Let's play a game of FizzBuzz! It works just like the popular childhood game "PopCorn", but with rules of math applied since math is fun, right? Just print out "Fizz" when the given number is divisible by 3, "Buzz" when it's divisible by 5, and "FizzBuzz" when it's divisible by both 3 and 5!
Let the game begin!
Input
A line containing an integer.
15Output
A line containing a string.
FizzBuzzFrom the following molar conductivities at infinite dilutions
^°m for Ba(OH)2 = 457.6 ohm-1cm2mol-1
^°m for Bacl2= 240.6 ohm-1cm2mol-1
^°m for NH4cl = 129.8 ohm-1cm2mol-1
Calculate the ^°m of NH4cl
the uncertainty associated with a temperature calculated from two readings of a 0oC and 110oC thermometer is 1oC.calculate the percentage uncertainty associated with a temperature difference of 8.0oC. give your answer to 2 significant figures
In a hittorf experiment ,a student electrolyzed aqueous AgNO3 solution using silver electrodes . The amount of AgNO3 in the anode compartment before electrolysis was 0.228g and the amount after electrolysis was 0.282g. during electrolysis it was found that 0.019g of copper was deposited in the copper colorimeter connected in series with the hittorf cell. Calculate the transport number of Ag+
