Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// recursive function to find sum from 1 to n
int recur_Sum(int n)
{ // base condition
if (n <= 1)
return n;
// recursive call
return n + recur_Sum(n - 1);
}
// main function
int main()
{
// variables
int n;
cout<<"Enter a number:";
// read the number
cin>>n;
// print the sum
cout<<"Sum of first "<<n<<" integer from 1 to "<<n<<" is:"<<recur_Sum(n);
return 0;
}
Explanation:
Read a number from user and assign it to variable "n".Call function recur_Sum() with parameter "n".This function will recursively call itself and find the Sum of first n numbers from 1 to n.Then function will return the sum.
Output:
Enter a number:10
Sum of first 10 integer from 1 to 10 is:55
In a parallel connection, the voltage is same in every branch.
Now, three <span>three resistors connected in parallel.
R1 = 2k ohm
</span>R2 = 6k ohm
R3 = 10k ohm
in parallel, net resisitance =
Now, putting the values, we get, R net = 1.30 k ohm.
Ans, voltage = 100 VDC
Thus, power =
= 7.69 Watt

Answer:
A <u>rootkit</u> is a set of software tools used by an attacker to hide the actions or presence of other types of malicious software, such as trojans, viruses, or worms.
Explanation:
A <u>rootkit</u> is a set of software tools used by an attacker to hide the actions or presence of other types of malicious software, such as trojans, viruses, or worms. Where a Rootkit provides features like remote access to users, it also opens ways for attackers. It helps in hiding the malicious software. Rootkits can be installed on the victim systems by phishing attack or social engineering techniques ..
