Answer:

The work of the cycle.

Explanation:

The area enclosed by the cycle of the Pressure-Volume diagram of a Carnot engine represents the net work performed by the cycle.

The expansions yield work, and this is represented by the area under the curve all the way to the p=0 line. But the compressions consume work (or add negative work) and this is substracted fro the total work. Therefore the areas under the compressions are eliminated and you are left with only the enclosed area.

A well insulated rigid tank contains 4 kg of argon gas at 450 kPa and 30 C. A valve is opened, allowing the argon to escape unti

natima [27]

Answer:

Final mass of Argon= 2.46 kg

Explanation:

Initial mass of Argon gas ( M1 ) = 4 kg

P1 = 450 kPa

T1 = 30°C = 303 K

P2 = 200 kPa

k ( specific heat ratio of Argon ) = 1.667

assuming a reversible adiabatic process

<u>Calculate the value of the M2 </u>

Applying ideal gas equation ( PV = mRT )

P₁V / P₂V = m₁ RT₁ / m₂ RT₂

hence : m2 = P₂T₁ / P₁T₂ * m₁

= (200 * 303 ) / (450 * 219 ) * 4

= 2.46 kg

<em>Note: Calculation for T2 is attached below</em>

Write a function call with arguments tensPlace, onesPlace, and userInt. Be sure to pass the first two arguments as pointers. Sam

Trava [24]

Answer:

#include <stdio.h>

void SplitIntoTensOnes(int* tensDigit, int* onesDigit, int DecVal){

*tensDigit = (DecVal / 10) % 10;

*onesDigit = DecVal % 10;

return;

}

int main(void) {

int tensPlace = 0;

int onesPlace = 0;

int userInt = 0;

userInt = 41;

SplitIntoTensOnes(&tensPlace, &onesPlace, userInt);

printf("tensPlace = %d, onesPlace = %d\n", tensPlace, onesPlace);

Write a statement that assigns freeBooks the appropriate value based on the values of the boolean variable isPremiumCustomer and

solniwko [45]

Write a statement that assigns freeBooks the appropriate value based on the values of the boolean variable isPremiumCustomer and the int variable nbooksPurchased is described below

Explanation:

Online Book Merchants offers premium customers 1 free book with every purchase of 5 or more books and offers 2 free books with every purchase of 8 or more books. It offers regular customers 1 free book with every purchase of 7 or more books, and offers 2 free books with every purchase of 12 or more books.

A statement that assigns freeBooks the appropriate value based on the values of the boolean variable isPremiumCustomer and the int variable nbooksPurchased. Here's what we have:

if(isPremiumCustomer = true){

if(nbooksPurchased >= 5));

freeBooks = 1;

}else if(nbooksPurchased >= 8){

freeBooks = 2;

}else {

if(nbooksPurchased >= 7);

freeBooks = 1;

}else if(nbooksPurchased >= 12){

freeBooks = 2;

}

We are getting an error of "illegal start of expression".

Two of the hints are "You are using an incorrect number somewhere in your solution" and "We think you might want to consider using: ==".

I do not want the answer, I just want pointed in the right direction.
