Answer:
Following are the code to this question:
file= open('book.txt') #open file
li= {} #define an empty list
for lines in file: # use for loop Split file data into words
d= lines.lower().strip(' !?').split() #define variable d that Add it to map
for val in d: #define loop to store data
if val not in li: #check value is not in list
li[val] = 0 #define list and assign value in 0
li[val] = li[val] + 1 #Sort the book data and add its value
m = sorted(li.items(),key = lambda x : -x[1]) #sorted value into the m variable
print(m[:10]) #print value
Output:

Explanation:
In the given python code first, we open the file "book.txt", in next line, an empty list is defined, that uses the for loop which can be described as follows:
- In the for loop is used, that reads the file data, and defines a variable "d", that stores the values into the map.
-
In the next line another loop is used, that check file values, if values are the same type so, it adds values and writes it.
- In the last line, m variable is used, that sorts the values and use the slicing to print its value.
Answer:
Effort = 120 Newton
Explanation:
Given the following data;
Mechanical advantage = 6
Load = 780 N
To find the effort required to lift the weight;
Mechanical advantage can be defined as the ratio of the load (weight) lifted by a simple machine to the effort (force) applied.
Mathematically, the mechanical advantage is given by the formula;

Making effort the subject of formula;

Substituting into the formula, we have;

Effort = 120 Newton.
