The pressure and temperature at the beginning of compression of a cold air-standard Diesel cycle are 100 kPa and 300K, respectiv

hram777 [196]

Answer:

Cut off ratio=2.38

Explanation:

Given that

$T_1=300K$

$P_1=100KPa$

$P_2=P_3=7200KPa$

$T_3=2250K$

Lets take $T_1$ is the temperature at the end of compression process

For air γ=1.4

$\dfrac{T_2}{T_1}=\left(\dfrac{P_2}{P_1}\right)^{\dfrac{\gamma -1}{\gamma}}$

$\dfrac{T_2}{300}=\left(\dfrac{7200}{100}\right)^{\dfrac{1.4-1}{1.4}}$

$T_2=1070K$

At constant pressure

$\dfrac{T_3}{T_2}=\dfrac{V_3}{V_2}$

$\dfrac{2550}{1070}=\dfrac{V_3}{V_2}$

$\dfrac{V_3}{V_2}=2.83$

So cut off ratio

$cut\ off\ ratio =\dfrac{V_3}{V_2}$

Cut off ratio=2.38

A binary star system consists of two stars of masses m1m1m_1 and m2m2m_2. The stars, which gravitationally attract each other, r

d1i1m1o1n [39]

Answer:

$a_c_2=\dfrac{a_c_1\times m_1}{m_2}$

Explanation:

The question is: <em>Find the magnitude of the centripetal acceleration of the star with mass m₂</em>

The <em>centripetal acceleration</em> is the quotient of the centripetal force and the mass.

$a_c=\dfrac{F_c}{m}$

Thus, you can write the equations for each star:

$a_c_1=\dfrac{F_c_1}{m_1}$

$a_c_2=\dfrac{F_c_2}{m_2}$

As per Newton's third law, the centripetal forces are equal in magnitude. Then:

$a_c_1\times m_1=a_c_2\times m_2$

Now you can clear $a_c_2$ :

$a_c_2=\dfrac{a_c_1\times m_1}{m_2}$

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;
