Answer:

While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.

If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.

If a 60 lb. load is placed on the platform, what will the pressure gauge reading be if the piston area is 5 sq.in? Give your ans

Doss [256]

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;

$Pressure = \dfrac{Force}{Area}$

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

Therefore;

$Pressure = \dfrac{Force}{Area} = \dfrac{60 \ lb}{5 \ in.^2} = 12\dfrac{lb}{in.^2} = 12 \ psi$

The gauge reading will be 12 psi.

Can someone answer this for me will award brainliest lol

Answer: Without GUI's being developed, we most likely would still be using terminal systems. Terminals require command/text input rather than mouse or other input. The invention of GUI's enabled people to use simpler input methods, rather then clunky text input systems. To sum, GUI's simplified the computer experience as we know today.

Hope this helped :)

Q4. Write down the JavaScript statements to perform the following tasks.

goldenfox [79]

Answer:

Explanation:

In Javascript, you can accept an input value by using the prompt() function and saving the input into a variable. In the following lines of code, I have declared the three variables at the beginning and then prompted the user to enter a value for each and saved the values in the correct variables. In Javascript length is a keyword so I used len instead.

let base, height, len;

base = prompt("Enter Base value: ");

height = prompt("Enter Height value: ");

len = prompt("Enter Length value: ");
