Answer:
The pressure gauge reading will be;
12 psi
Explanation:
The question relates to relationship of pressure and area
The given parameters for the measurement are;
The weight of the load = 60 lb
The required area of the piston = 5 in.²
Pressure exerted by a force can be defined as follows;

The weight of the load = The force applied by the load
Therefore;

The gauge reading will be 12 psi.
Answer:
\n
Explanation:
readline() method is used to read one line from a file. It returns that line from the file.
This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.
So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.
For example if the file "abc.txt" contains the lines:
Welcome to abc file.
This file is for demonstrating how read line works.
Consider the following code:
f = open("abc.txt", "r") #opens the file in read mode
print(f.readline()) # read one line from file and displays it
The output is:
Welcome to abc file.
The readline() method reads one line and the print method displays that line.
Javascript can be executed i believe. but i just googled it,check it for yourself
