1. A loudspeaker of mass 18.0 kg is suspended a distance of h = 2.20 m below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 4.00 m.

a) What is the weight of the speaker?

b) What is the tension TTT in each of the cables? (Use 9.81 m/s2m/s2 for the magnitude of the acceleration due to gravity).

2. A 11.1 kg runaway grocery cart runs into a spring with spring constant 275 N/m and compresses it by 65.1 cm.

a) What was the speed of the cart just before it hit the spring?

b) What is the total energy stored in the spring after the collision?

c) What is the maximum force exerted on the cart by the spring during the collision? (Give the magnitude of the force only)

#Write a function called multiply_file_by_index. This function
#should take two parameters, both strings. The first string is
#the filename of a file to which to write (output_file), and
#the second string is the filename of a file from which to read
#(input_file).
#
#In the input file, there will be an integer on every line.
#To the output file, you should write the integer from the
#original file multiplied by the line number on which it
#appeared. You should assume that the first line of the file
#is line 1 (which is different from a list, where the first item
#is at index 0).
#
#For example, if the input file contained this text:
#1
#4
#3
#7
#6
#
#Then the output file would contain this text:
#1
#8
#9
#28
#30

#Add your code here!

#The code below will test your function. You can find the two
#files it references in the drop-down in the top left. If your
#code works, output_file.txt should have the text:
#1
#8
#9
#28
#30
multiply_file_by_index("output_file.txt", "input_file.txt")
print("Done running! Check output_file.txt for the result.")

#If you accidentally erase input_file.txt, here's its original
#text to copy back in (remove the pound signs):
#1
#4
#3
#7
#6

2.

#Write a function called search_inside_files. search_inside_files
#should have two parameters: a filename and a string to search for.
#search_inside_files should return a list of line numbers as integers
#where the string appeared. Note that the string at that index does
#not need to BE the search string, but rather must just contain it.
#You should assume that the first line in a file is line 1, not line
#0.
#
#For example, if the files contents was:
#cat
#cats
#dog
#dogs
#catsup
#
#Then search_inside_files("input_file.txt", "cat") would return
#[1, 2, 5], because "cat" appears on lines 1, 2, and 5.
#
#Make sure the list you return is sorted from lowest line number to
#highest.

#Add your code here!

#The code below will test your function. You can find the file it
#references in the drop-down in the top left. If your code works,
#this should print:
#[1, 2, 5]
#[3, 4]
#[2, 5]
#[5]
#[]
print(search_in_files("input_file.txt", "cat"))
print(search_in_files("input_file.txt", "dog"))
print(search_in_files("input_file.txt", "cats"))
print(search_in_files("input_file.txt", "sup"))
print(search_in_files("input_file.txt", "aardvark"))

#You've been sent a list of names. Unfortunately, the names
#come in two different formats:
#
#First Middle Last
#Last, First Middle
#
#You want the entire list to be the same. For this problem,
#we'll say you want the entire list to be First Middle Last.
#
#Write a function called name_fixer. name_fixer should have two
#parameters: an output filename (the first parameter) and the
#input filename (the second parameter). You may assume that every
#line will match one of the two formats above: either First Middle
#Last or Last, First Middle.
#
#name_fixer should write to the output file the names all
#structured as First Middle Last. If the name was already structured
#as First Middle Last, it should remain unchanged. If it was
#structured as Last, First Middle, then Last should be moved
#to the end after a space and the comma removed.
#
#The names should appear in the same order as the original file.
#
#For example, if the input file contained the following lines:
#David Andrew Joyner
#Hart, Melissa Joan
#Cyrus, Billy Ray
#
#...then the output file should contain these lines:
#David Andrew Joyner
#Melissa Joan Hart
#Billy Ray Cyrus

#Add your code here!

#The code below will test your function. You can find the two
#files it references in the drop-down in the top left. If your
#code works, output_file.txt should have the text:
#David Andrew Joyner

name_fixer("output_file.txt", "input_file.txt")

You have been appointed as audit team leader to audit Badr Hospital, a private hospital, that owns
several branches across Oman, for the end of year. The hospital has been operating for the last seven
years and has just been your audit firm’s client this year. The hospital has been doing well in the last
four years, earning sufficient amount of income to establish four branches already in the big cities in
Oman. Just last year, the hospital established its internal audit department. Previous auditor disclosed
that recently the hospital has been having problems in its data base and patient records due to the
increase in number of patients and consistent resignations of employees assigned on recording
complaining of small salary packages. Your team’s initial assessment discovered that total assets of
the hospital as of December 31, 2019 amounted to OMR 400 million, total revenue OMR 50 million
and for the first time in seven years, they had a net loss amounting to OMR 5 million. Long term
debt amounted to OMR 400 million, which was constantly paid late in the last two years. In an
attempt to solve their data base problem, last year also, the company has computerized its patient
recording system by outsourcing the software from a company abroad. The management is very
apprehensive to get the hospital back on its feet and expects your team to report on weaknesses in
design and implementation of internal controls on top of the usual audit of financial statements.
Required: Discuss matters that you would consider in developing the audit strategy for Badr
Hospital.
