Answer:

2.5mA

Explanation:

The principle of superposition states that

instead of having to solve for the voltage/current through a resistor when all the power source are there, you're allowed to solve for the voltage/current through a resistor for each independent source separately and add them up in the end later for the final result.

General Step of Solving:

Choose which resistor you're trying to solve for.
Pick one of the power source and keep it on. Turn all other power sources off. Then solve for the voltage/current through the resistor of your choice.
Repeat step 2 for the other remaining power source.
Add up all the voltage/current that you found.

So.

1.) Solve for voltage through the 1k resistor when only the 15V source is on. i.e. turn off the 10V source.

2.) Solve for voltage through the 1k resistor when only the 10V source is on. i.e. turn off the 15V source.

3.) Add up the two voltage you found together.

You should get V_1k = 2.5V

so the Current through it must be I_1k = 2.5/1k = .0025A = 2.5mA

What steps would you take to design an improved toothpaste container?

algol [13]

Answer:

A. Identify the need, recognize limitations of current toothpaste containers, and then brainstorm ideas on how to improve the existing

Explanation:

To design an improved toothpaste container, we must identify the needs of the customer, one of the major need is to make the container attractive to the sight. This is the first thing that will prompt a customer to wanting to buy the product (The reflectance/appearance).

Then recognize the limitation of the current design, what needed change. This will help in determining what is needed to be included and what should be removed based on identified customers need.

The last step is to brainstorm ideas on how to improve the existing designs. Get ideas from other colleagues because there is a saying that two heads are better than one. This will help in coming to a reasonable conclusion on the new design after taking careful consideration of people's opinion.

Create a program, using at least one For Loop, that displays the Sales Amounts in each of 4 regions during a period of three mon

kari74 [83]

Answer:

C++ code explained below

Explanation:

/*C++ program that prompts sales for four regions of three sales and prints

the sales values to console */

#include<iostream>

#include<iomanip>

#include<cstring>

using namespace std;

int main()

{

//set constant values

const int SALES=3;

const int REGIONS=4;

//create an array of four regions

string regionNames[]={"Region 1","Region 2","Region 3","Region 4"};

//create a 2D array to read sales

int sales[REGIONS][SALES];

//read sales for four regions

for(int region=0;region<REGIONS;region++)

{

cout<<regionNames[region]<<endl;

for(int sale=0;sale<SALES;sale++)

{

cout<<"Enter sales ";

cin>>sales[region][sale];

}

//print sales

for(int region=0;region<REGIONS;region++)

{

cout<<regionNames[region]<<"-";

for(int sale=0;sale<SALES;sale++)

{

cout<<setw(5)<<sales[region][sale];

}

cout<<endl;

}

//pause program output on console

system("pause");

return 0;

To determine the factor of safety for the states of plane stress. We have to first understand the concept of Coulomb-Mohr theory.

Mohr–Coulomb theory is a mathematical model describing the response of brittle materials such as concrete, or rubble piles, to shear stress as well as normal stress.
