Answer:
Mouse, Keyboard, Headphones, Mouse dongle.
Explanation:
Input Device Definition: A piece of equipment/hardware which helps us enter data into a computer is called an input device. For example keyboard, mouse, etc.
Answer:
Input devices are those devices connected to the computer which are used to enter the data. Input can be in the form of text, graphics and sound. There are different types of input devices for different types of inputs.
Explanation:Today, input devices are important because they are what allows you to interact with and add new information to a computer. For example, if a computer had no input devices, it could run by itself but there would be no way to change its settings, fix errors, or other various user interactions. Also, if you wanted to add new information to the computer (e.g., text, command, document, picture, etc.), you wouldn't be able to do so without an input device.
What is the result of the expression: int('1750.0')?
Answer:
Value error
Explanation:
The result of the expression: int ('1750.0') is an error: the string does not represent an integer value. The correct option is a.
What is an expression?A "statement," which is just a single unit of execution and returns nothing, is different from an "expression," which is a mixture of values and functions that are combined and processed by the compiler to create a new value.
A mix of operators, constants, and variables makes up an expression. To produce a value, an expression can include one or more operands and one or more operators. A programming error is a mistake in the way a program functions. Although the software can execute, it does not perform as planned.
Therefore, the correct option is a. An error: the string does not represent an integer value.

This program will output a right triangle based on user specified height triangleHeight and symbol triangleChar. It is strongly suggested to use the for loop for this solution.
(1) The given program outputs a fixed-height triangle using a * character. Modify the given program to output a right triangle that instead uses the user-specified triangleChar character.
(2) Modify the program to use a nested loop to output a right triangle of height triangleHeight. The first line will have one user-specified character, such as % or *. Each subsequent line will have one additional user-specified character until the number in the triangle's base reaches triangleHeight. Output a space after each user-specified character, including after the line's last user-specified character.
Example output for triangleChar = % and triangleHeight = 5:
Enter a character:
%
Enter triangle height:
5
%
% %

Braking abruptly.
Answer: C. Slowing down gradually
Explanation:
A and B suck up the gas immediately since you are using much more of it. When you brake abruptly, you are not only wasting gas, but you are also damaging your tires. Therefore, the most appropriate answer is C.
I hope this helps!! Pls mark brainliest :)
The thing that may help drivers conserve gasoline is Slowing down gradually. third option is correct.
What is conservation of gasolineThere are three fundamental quantities in mechanics that are conserved. These are power, forward motion, and angular momentum. It takes time and fuel to accelerate and get one's vehicle back up to the speed of traffic every time one needs to stop fast.
Seeing far ahead of the car allows drivers to slow down gradually or change lanes to minimize idling, which improves gas consumption. Slowing down gradually is something that may assist drivers in saving petrol. The third choice is right.

Numerous engineering and scientific applications require finding solutions to a set of equations. Ex: 8x + 7y = 38 and 3x - 5y = -1 have a solution x = 3, y = 2. Given integer coefficients of two linear equations with variables x and y, use brute force to find an integer solution for x and y in the range -10 to 10.
Ex: If the input is:
8
7
38
3
-5
-1
Then the output is:
x = 3 , y = 2
Use this brute force approach:
For every value of x from -10 to 10
For every value of y from -10 to 10
Check if the current x and y satisfy both equations. If so, output the solution, and finish.
Ex: If no solution is found, output:
There is no solution
Assume the two input equations have no more than one solution.
Note: Elegant mathematical techniques exist to solve such linear equations. However, for other kinds of equations or situations, brute force can be handy.
The brute strength method determines if each x and y value satisfies both conditions. To do this, we must iterate through each result in the specified range and insert them into both models.
What are Elegant mathematical technique?ALGORITHM :
1. Take the values of all coefficients and SET flag = FALSE
2. Run a FOR loop for x in range (-10, 11). 11 won't be included.
2a. Inside the first FOR, start the y FOR loop in range(-10,11). 11 won't be included
2b. Inside the y FOR loop, check IF for a particular value of x and y both the equations satisfied.
2c. If yes, set flag TRUE and print values of x and y.
2d. ELSE the flag stays FALSE.
END FOR Y
END FOR X
3. Check if flag = FALSE, then print NO SOLUTION
PYTHON CODE :
a=int(input()) #taking input for each coefficient
b=int(input())
c= int(input())
a1= int(input())
b1= int(input())
c1= int(input())
flag = False
for x in range(-10,11): #checking for all values of x in range -10 to 10
for y in range(-10,11): #checking for all values of x in range -10 to 10
if (a x + b y – c == 0) and (a1*x + b1*y - c1 == 0) : #checking if the x and y values satisfy the equation
flag = True #setting the flag if solution is found
print('Solution : x = {-10, 10}, y = {-10, 10}'.format(x,y)) #if they satisfy print x & y
if flag = False : #if flag stays false, that means there is no solution
