a. Write algorithm using pseudocode and flowchart that uses while loops to perform the
following steps:
i. Prompt the user to input two integers: firstNum and secondNum note that firstNum
must be less than secondNum.
ii. Output all odd numbers between firstNum and secondNum.
iii. Output the sum of all even numbers between firstNum and secondNum.
iv. Output the numbers and their squares between firstNum and secondNum.
v. Output the sum of the square of the odd numbers between firstNum and secondNum.

c. Redo Exercise (a) using do. . .while loops.
In crank and slotted lever quick return mechanism, the crank length is (100 +X )mm and the distance between the fixed center is (225+X)mm. The length of the slotted lever is (525+X)mm. Determine the ration of time of cutting stroke to time of return stroke. Also calculate the length of the stroke . Note where X is two digit number made from the last two digit of the registration number of the students For example if the reg. no. of the student is 11912081 then X=81 and crank length is 80+81=161mm Draw the neat and clean diagram with proper scale. Rough drawings will not be considered.
The sum of the first 3 terms of geometric sequence is 189 and the sum of the first 6 terms is 182.
If a trolley of mass 5kg moves at 4.m/s east across a frictionless horizontal surface and a box of mass 1,5 kg is dropped onto the trolley then the trolley and the box continues to move in the same direction.calculate the impulse of the trolley.

Consider the following events: Scientists reveal that
eating oranges decreases the risk of diabetes, and at
the same time, farmers use a new fertilizer that makes
orange trees produce more oranges. Illustrate and
explain what effect these changes have on the
equilibrium price and quantity of oranges.
The market for pizza has the following demand and
supply schedules:
Price Quantity Demanded Quantity Supplied
$4 135 pizzas 26 pizzas
5 104 53
6 81 81
7 68 98
8 53 110
9 39 121
a. Graph the demand and supply curves. What are
the equilibrium price and quantity in this market?
b. If the actual price in this market were above the
equilibrium price, what would drive the market
toward the equilibrium?
c. If the actual price in this market were below the
equilibrium price, what would drive the market
toward the equilibrium?
playing rock ‘n’ roll music at high volume. Placido loves opera and hates rock ‘n’ roll. Unfortunately, they are next-door neighbors in an apartment building with paper-thin walls. a. What is the externality here? b. What command-and-control policy might the landlord impose? Could such a policy lead to an inefficient outcome? c. Suppose the landlord lets the tenants do whatever they want. According to the Coase theorem, How might Bruno and Placido reach an efficient outcome on their own? What might prevent them from reaching an efficient outcome?
Q9: Calculate the standard free energy change for the combustion of methane at 250oC. Again, assume that all reactants and products are gases. 3 SIG FIGURES.
Q10 PART A: Calculate the free energy change for the combustion of methane at 250oC. Assume that all reactants and products are gases and that the partial pressures of the various gases of interest are: methane = 0.56 atm, oxygen = 0.45 atm, carbon dioxide = 2.10 atm, water = 3.40 atm.
PART B: What is the value of the equilibrium constant for the reaction described in Question 10? Provide an answer correct to 2 significant figures.
PART C: Based on your calculations in previous problems, at what temperature will the combustion of methane be at equilibrium? Provide an answer correct to 2 significant figures
