The expression for the number of molecules in a Maxwellian gas having speeds in the range vto v+ dv is
dNv= 4πN(m÷2πkbT)^3/2 v^2exp[-(mv^2÷2kbT)]dv using this relation, obtain an expression for most probable speed
explain why the following experiments are not binomial.
A. Rolling a die until a 6 appears.
B. Asking 20 people how old they are.
C. Drawing 5 cards from a deck for a poker hand.
Discuss the sedimentation in brownian motion and show that during sedimentation, particle concentration decreases exponentially as height increases
Calculate the temperature at which root mean square speed of gas molecules is double of its speed at 27°c pressure remaining constant
Create a class called Match that will have team objects and be used for creating a Match of play.
Data Members:
-This class has two data members named HomeTeam and VisitorTeam which are of type Team, they will store that two teams that will play the Match.
Methods:
-This class doesn’t have a default constructor, it only has one constructor which receives two Team object that will be assigned to HomeTeam and VisitorTeam. setTeams(),which receives two Team object that will be assigned to HomeTeam and VisitorTeam.
-playMatch(), simulates match play by calling the scoreGoals methods of each team.
-getPlayGound(), returns the ground of play which is the HomeGound of the HomeTeam. -isDrawMatch(), will return true if the Match is a draw and false if there is a winner.
-The match is a draw if the goals of the teams are equal. getWinner(), returns the team which won the match, a team wins if its goals is higher than the goals of the other team.
-getLoser(), returns the team which lost the match.

2. Three is a Crowd
by CodeChum Admin
This one’s pretty simple as well, but I hope you haven’t forgotten how to create a new line!
Instructions:
Input three random characters and make sure they are inputted on different lines.
Print out the three strings in order, each on a different line, using only 1 std::cout statement and newline characters (\n). An initial code with 1 std::cout is already provide for you. Don't add more std::cout's!
Input
Three lines containing a character on each.
A
B
C
Output
Three lines containing a character on each.
A
B
C
3. Input + Addition
by CodeChum Admin
Hopefully you haven't forgotten about your previous lesson, because you're going to need it for this one.
Instructions:
Input two integers (one per line) and make sure to store them in variables.
Add the two integers and print out their sum!
Input
Two lines containing an integer on each.
6
6
Output
A line containing the addition of the two inputted integers.

4. Decimal x Decimal
by CodeChum Admin
Now that we're done with integers, we're moving on to decimals!
Instructions:
Input three decimal numbers in one line separated by spaces, and make sure to store them in different variables.
Multiply the 1st and 2nd decimal numbers, and store the product into a variable.
Then, divide the product of the 1st and 2nd decimal numbers with the 3rd decimal number, then print out its quotient, with 2 decimal places.
Input
A line containing three decimal numbers with two decimal places separated by a space.
*Test Case 1
1.53·2.25·1.23
Output
A line containing the result with two decimal places.
2.80
*Test Case 2
Input
1.9 2.5 3.75
Expected Output
1.27
Calculate the molality of a solution prepared from 15.25 g of NaCl in 1.50 kg of water.
