You can raise an object to a height of 2 meters by pulling down a distance of 8 meters on a pulley with a force of 40 N. How heavy an object can you lift with his effort?

Answers

Answer 1

Answer:

160 N

Explanation:

Since, work done by effort = work done by load,

Fd = F'd' where F = effort force = 40 N, d = distance moved by effort = 8 m, F = load and d' = distance moved by load = 2 m.

So, Fd = F'd'

40 N × 8 m = F' × 2 m

320 Nm = 2F m

So, F = 320 Nm/2m

= 160 N

So, the object that can be lifted is an object of 160 N

An application's certificate indicates the application -
A is regularly updated
B cannot be removed
C is installed
D is authentic

Answers

Answer:

D. is authentic

Explanation:

Authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.

Biometrics, smart cards, digital certificates, and picture passwords are various methods that can be used to perform an authentication.

Hence, an application's certificate indicates the application is authentic. These certificates are generally referred to as digital certificates.

When an end user installs a software application or program, the computer or mobile device would automatically verify the digital signature contained in the software. If the authentication process is successful, the software would be installed. Else, the installation process would be terminated.

The correct answer is A. Cursor

Answer:

A. Cursor.

Explanation:

If you read the answer choices carefully, none of them fit in with the "flashing symbol" category, even though some of them might allow you to input text. However, you have used a computer before to type out text, just like how you typed this question to Brainly. Therefore, you should also know how a cursor acts. It flashes and allows you to input text as well.

Therefore, A is the correct answer to this question.

Please help w/ Java, ASAP!!!!

Answers

Answer:

B

Explanation:

When you have a method that is copying values from one array into another, you first have to initialize a new array which you can copy the values into. This is done by using the provided value "count".

   int [ ] nums = new int [count];

Second, you have a "for each" loop that iterates over each index in the first array, and assigns the value at that index to the same index location in the copy array. In a "for each" loop, the variable "val" represents the content of an index, not an iterated value itself. This is why we can just do this inside the loop:

  nums[ j ] = val;

That said, you still need "j" to be there and increment because we still need a tracking value for the current index in the copy array.

   int j = 0;

   for (int val: array)

   {

     copyArray[j] = val;

    j++;

   }

Third, you return the copy version of the array.

return nums;

What is CPU?

A central processing unit, sometimes known as a CPU, is a piece of electronic equipment that executes commands from software, enabling a computer or other device to carry out its functions.

The part of a computer that obtains and executes instructions is called the central processing unit (CPU).

A CAD system's CPU can be thought of as its brain. It is made up of a control unit, a number of registers, and an arithmetic and logic unit (ALU). The term "processor" is frequently used to refer to the CPU.

The size, speed, sophistication, and price of a printer varies. It is a device that receives text and graphic output from a computer and transmits the information to paper.

Thus, the correct option is D.
