Answer:

22.5 s is the correct answer to the given question .

Explanation:

Given that

d=7.5km=7.5\times 10^3 m

For light:

We know that speed of light c

c=3\times 10^8 m/s

We know that

Distance = Speed \times timed=C\time tt=\dfrac{D}{t}t=\dfrac{7.5\times 10^3}{3\times 10^8}\ st=2.5\times 10^{-5}st=0.025 ms

For thunder :

Speed of sound ,v=332 m/s

Time\  taken\  by\  sound \\t\’=\dfrac{7500}{332}=22.59 s

Therefore the difference between time is given as follows

\Delta t= t' - \ t=22.59-2.5\times 10^{-5}=22.59 s

22.5 is the answer

Determine the following information about each value in a list of positive integers.
german

Answer and Explanation:

Using Javascript:

test7_11_13(num){

If(num%7===0||num%11===0||num%13===0){

Console.log("yes it is a multiple of 7,11 or 13");

}

else{

Console.log("It is not a multiple of any of the numbers");

}

function(num){

var makeString= num.toString();

var splitString= makeString.split("");

var makeNumber= splitString.map(Number());

var New_number= makeNumber.reduce(function(a, b) {

return a+b};,0)

}

If(New_number%2===0){

Console.log("it's an even number");

}

else{

Console.log("it's an odd number")

}

If(num%2===0||num%3===0||num%5===0||num%7===0||num%11===0){

console.log("it's not a prime number");

}

else{

console.log("it's a prime number");

}

}

From the above we have used javascript if..else statements to test the conditions for each question and output the answer to the console using console.log(). In the last part for prime number, you could also choose to use else if statements(if,else if, else if) to test the value of the num parameter and output if it's a prime number.

your manager asked you to set up a secure network connection at a remote site to move over some back ups. what protocol what do
Ivan

The protocol that should be used to establish a secure network connection for backups is SSH.

<h3>Secure Shell</h3>

SSH stands for <u>Secure Shell</u>. SSH is a <u>protocol that allows users to remotely control and modify servers</u>. SSH is commonly used by administrators to manage certain systems or applications remotely. So the admin can enter the computer via the network, then run various commands to modify or manage files from one computer to another.

SSH has several crucial functions for managing data transfer traffic. Specifically, the following are the functions and benefits of SSH:

  • Securing remote access to SSH-enabled systems or network devices for the user and processing them automatically.
  • SSH will automatically terminate the connection if there is suspicious activity on the connection used. So you can avoid various cyber threats such as IP and DNS spoofing, data manipulation, illegal tracking, and others.
  • Perform automatic and secure file transfers.
  • Launch commands securely on remote devices or systems.
  • Perform secure component management of network infrastructure.
