In solvolysis of alkyl halides, substitution of alkyl groups at the B 'carbon atom increases E1 over SN1.
Objective: Distinguish between electromotive forces and potential differences.
Material: A circuit Diagram
Procedure:
- Draw a circuit diagram with two batteries, 1 light bulb, and switch. You can apply your creativity provided that the appropriate symbols are used.
- Label the electromotive force and the potential difference.
Question: How does an electromotive force differ from potential difference?
- Create a project named LabExer2
- Construct a simple purchasing program based on the UML Class Diagram below.
- itemName: String

storing the input to the next variable name based on data type
For String s.nextLine()
For int s.nextInt()
For double: s.nextDouble()
The current drawn from the cell when the wire is connected across A as shown is 0.3A but reduced to 0.25A, when the wire is removed leaving
A. Alone connected to the the cell determine
B. The E.M.F of the cell
C. The internal resistance of the cell
Find the expected value of the random variable X and its variance having the following density function:
f(x) = 5 (1-x4) 0<x<2
= 0 elsewhere
Full details math and explain.
Three resistors with values of 60.0Ω, 30.0 Ω, and 20.0 Ω, respectively, are
connected in series to a 110.0 V battery of negligible internal resistance. (a) Draw a circuit diagram and find the (b) equivalent resistance of the combined resistors, (c) current flowing through each resistor, (d) voltage drop across each resistor.
Four resistors when connected in series give an equivalent
resistance if 75.0 Ω. Three of the resistors have values 18.0 Ω, 6.0 Ω, and
24.0 Ω, respectively. What is the resistance of the fourth resistor?
What resistance must be connected in parallel to 60 Ω resistor to
reduce the combined resistance of 15 Ω?
Write a C++ program that prompts a user for three integers- the first denoting a month (1 to 12), the second denoting a day (1 to 31) and the third denoting a year. The output is displayed as "month day, year" string where month represents the name of the month.
For example, if inputs are 12, 15 and 2020 respectively, the output is December 15,
Write a program in C++ that reads text from the keyboard and stores it in a file named “File1.txt”. Also, for each of the specified prototypes given below, write the function definitions.
void copyselc(ifstream& fp, ofstream& fp1):This function reads the contents of the file “File1.txt” and copies those lines from the file that begin with the character „#‟ to the file named “File2.txt”.
void checksize(ifstream& fp1,ifstream& fp2):This function reads two files “File1.txt” and “File2.txt” and counts the number of characters in both the files. If the count of characters in both the files is same, then the function should print the message “Both Files are of the same size” else it should display “Size of the files is not same”.
void dispNumNames(ifstream& fp):Assuming that the file “File2.txt” may also contain numbers (1 to 5), this function will read the contents from the file and display the number names for any numbers encountered.
