The current in a resistor is 5.0 A, and its power is 60 W. What is the voltage?

alexandr1967 [171]

The voltage on a resistor will be "12 V".

According to the given question,

Current,

I = 5.0 A

Power,

P = 60

As we know the formula,

→ $Power (P)= Current(I)\times Voltage (V)$

or,

→ $V = \frac{P}{I}$

By putting the giving values, we get

→ $= \frac{60}{5}$

→ $= 12 \ V$

Thus the solution above is right.

The Sleeping-Barber Problem:

s2008m [1.1K]

Answer:

Explanation:

Following are the Semaphores:

Customers: Counts waiting customers;

Barbers: Number of idle barbers (0 or 1)

mutex: Used for mutual exclusion.

Cutting: Ensures that the barber won’t cut another customer’s hair before the previous customer leaves

Shared data variable:

count_cust: Counts waiting customers. ------------copy of customers. As value of semaphores can’t access directly.

// shared data

semaphore customers = 0; semaphore barbers = 0; semaphore cutting = 0; semaphore mutex = 1;

int count_cust= 0;

void barber() {

while(true) { //shop is always open

wait(customers); //sleep when there are no waiting customers

wait(mutex); //mutex for accessing customers1

count_cust= count_cust-1; //customer left

signal(barbers);

signal(mutex);

cut_hair();

}

void customer() {

wait(mutex); //mutex for accessing count_cust

if (count_cust< n) {

count_cust= count_cust+1; //new customer

signal(customers); signal(mutex);

wait(barbers); //wait for available barbers get_haircut();

}

else { //do nothing (leave) when all chairs are used. signal(mutex);

}

cut_hair(){ waiting(cutting);

}

get_haircut(){

get hair cut for some time; signal(cutting);

}

Given a sorted array of integers created on the heap, its size and a new integer, design a function which will enlarge the array

Debora [2.8K]

Using the computational language in C++ to write a code that will organize the values in an array through a mathematical condition.

<h3>writing code in C++</h3>

#include <bits/stdc++.h>

using namespace std;

int getIndexInSortedArray(int arr[], int n, int idx)

{

/* Count of elements smaller than current

element plus the equal element occurring

before given index*/

int result = 0;

for (int i = 0; i < n; i++) {

if (arr[i] < arr[idx])

result++;

if (arr[i] == arr[idx] && i < idx)

result++;

}

return result;

}

int main()

{

int arr[] = { 3, 4, 3, 5, 2, 3, 4, 3, 1, 5 };

int n = sizeof(arr) / sizeof(arr[0]);

int idxOfEle = 5;

cout << getIndexInSortedArray(arr, n, idxOfEle);

return 0;

}
