How many kilojoules are released when 1.95 mol
of H202 reacts?
The intrinsic temperature of a semiconductor is the temperatures at which the intrinsic
carrier concentration equals the impurity concentration. Find the intrinsic temperature for a
silicon sample doped with 1015 phosphorus atoms/cm3
.
Two point charges are located on the positive x-axis of a co-ordinate system. Charge is 2.0cm from the origin, another charge is 4.0cm from the origin. What is the total force exerted by these two charges on a charge located at the origin?
Calculate the location of Ei in silicon at liquid nitrogen temperature (77 K), at room
temperature (300 K), and at 100 °C (let mp =1.0 m0 and mn= 0.19 m0). Is it reasonable to assume
that Ei is in the center of the forbidden gap?
Derive an expression for density of state for particle 3-D crystal having mass m with
energy ranging between E and E + dE
C++ program) that will accept an integer value in the range of 5-95 inclusive. Your solution should also ensure that input values ar in multiples of 5. Based on valid input, your solution should calculate how many coins of each denomination should be returned, and display this to the user. Coin values are 50, 20, 10 and 5. The solution should aim to give as much of the higher valued coins as possible. For example, a poor solution for an input of 30 cents would give six 5 cent coins. A correct solution would give a 20 cent coin and a 10 cent coin. After each output, the user should be asked whether they wish to continue or exit/terminate the program. Your solution (algorithm and program) should be designed using a modular approach. This requires the submission of a structure chart, a high level algorithm, and subsequent decompositions of each step (i.e. low-level algorithms). Hint 1- multple of 5 condition. 2- do while loop in switch to terminate the question. 3- no of inp is divisible of 5
(True or False): In relational databases, the link between two tables is that the primary key of one table is the foreign key in the other table. Write a paragraph response on why it's true or false.
Question: In the fourth query, we use the WHERE and HAVING clauses. Please select the right choice for the relationship between these two clauses.
- WHERE clause is used for filtering rows prior to the execution of aggregate functions, while the HAVING clause is used for filtering rows after the execution of aggregate functions.
- WHERE clause is used for filtering rows after the execution of aggregate functions. The HAVING clause is used for filtering rows prior to the execution of aggregate functions.
- The WHERE clause can be exchanged to use the HAVING clause.
- The HAVING is not a clause in SQL queries.

c) Clearly describe substitution effect and income effect for a fall in price for a normal good and an inferior good
A class has an integer data member ‘I’ and a function named ‘printNum’ to print the value of ‘I’. Its subclass also has an integer data member ‘j’ and a function named ‘printNum’ to print the value of ‘j’. Make an object of the subclass and use it to assign a value to ‘I’ and to ‘j’. Now call the function ‘printNum’ by this object.
