Which of the following equations represents the resultant vector of two forces F_1 and
F_2 acting at an angle
\theta apart starting from the same origin? i.e. calculate F1 + F2. Refer to the image below for an illustration. Remember that when adding vectors, the tail of one vector needs to connect to the head of another.
Match the following dimensions with the correct terms
You have already copied the below mentioned chaos program (printed below for your convenience) into your lab0.py file on your computer. The program is taken from the book Python Programming: An Introduction to Computer Science, (Third Edition), John Zelle, Franklin Beedleprint("This program illustrates a chaotic function")x = float(input("Enter a number between 0 and 1: ")) #taking input from userfor i in range(10): x = 3.9 * x * (1 - x) print(x)
Modify the program to print more than 10 values of 'x'.
Run the modified program. Select Run -> Run Module.When the program asks user to input a value between 0 and 1, enter 0.15. What is the 18th value printed ?
You have already copied the below mentioned chaos program (printed below for your convenience) into your lab1.py file on your computer. The program is taken from page 10 of the book Python Programming: An Introduction to Computer Science, (Third Edition), John Zelle, Franklin Beedleprint("This program illustrates a chaotic function")x = float(input("Enter a number between 0 and 1: ")) #taking input from userfor i in range(10): x = 3.9 * x * (1 - x) print(x)
Modify the program so that it only prints the final value of x. Don't change the range.
Run this program and try it with different input values. Select Run -> Run Module.

What does an element "i" in the Quiz Navigation block indicate?
Is there a penalty if you check a quiz question answer and it is wrong, or can you carry on to get full marks by making enough tries until you finally get it right? In particular, what is a typical penalty (as a %) for checking a question and getting it wrong? Enter your answer in the box below.
For example, if you think that there is no penalty, enter 0. If you think that the penalty is 30% per check, enter 30. (Round your answer to 2 decimal places)
