R₂ and R₃ can be replaced by:

R_5 =  \frac{1}{\frac{1}{R_2} + \frac{1}{R_3}} = 106 \frac23

The total R of the circuit is R₁+R₅+R₄ = 706 2/3

So the current in the circuit I=V/R is 100/(706 2/3) = 15/106 A
(I'm deliberately not trying to round the result)

The voltage drop over R₄ is V=I*R = 15/106 * 500 ≈ 70

So answer C would be my choice.

Paha777 [63]

Answer:

Check the explanation

Explanation:

CODE:

#include <iostream>

#include <iomanip>

using namespace std;

double getLoanAmount() { // functions as per asked in question

double loan;

while(true){ // while loop is used to re prompt

cout << "Enter the car loan amount ($2,500-7,500): ";

cin >> loan;

if (loan>=2500 && loan <= 7500){ // if the condition is fulfilled then

break; // break statement is use to come out of while loop

}

else{ // else error message is printed

cout << "Error: $"<< loan << " is an invalid loan amount." << endl;

}

}

return loan;

}

double getMonthlyPayment(){ // functions as per asked in question

double monthpay;

while(true){ // while loop is used to re prompt

cout << "Enter the monthly payment ($50-750): ";

cin >> monthpay;

if (monthpay>=50 && monthpay <= 750){ // if the condition is fulfilled then

break; // break statement is use to come out of while loop

}

else{ // else error message is printed

cout << "Error: $"<< monthpay << " is an invalid monthly payment." << endl;

}

}

return monthpay;

}

double getInterestRate(){ // functions as per asked in question

double rate;

while(true){ // while loop is used to re prompt

cout << "Enter the annual interest rate (1-6%): ";

cin >> rate;

if (rate>=1 && rate <= 6){ // if the condition is fulfilled then

break; // break statement is use to come out of while loop

}

else{ // else error message is printed

cout << "Error: "<< rate << "% is an invalid annual interest rate." << endl;

}

}

return rate;

}

int main() {

cout << setprecision(2) << fixed; // to print with 2 decimal places

int month = 0; // initializing month

// calling functions and storing the returned value

double balance= getLoanAmount();

double payment= getMonthlyPayment();

double rate= getInterestRate();

rate = rate /12 /100; // as per question

// printing as per required in question

cout << "Month Balance($) Payment($) Interest($) Principal($)"<< endl;

while(balance>0){ // while the balance is more than zero

month = month + 1; // counting Months

// calculations as per questions

double interest = balance * rate;

double principal = payment - interest;

balance = balance - principal;

// printing required info with proper spacing

cout <<" "<< month;

cout <<" "<< balance;

cout <<" "<< payment;

cout <<" "<< interest;

cout <<" "<< principal << endl;

}

cout << "Months to repay loan: " << month << endl; // displaying month

cout << "End of Banker Bisons";

Because of the abundance of water on planet Earth, hydrogen gas (H2) is a candidate in the search for a replacement for petroleu
Dennis_Churaev [7]

The reason why plants are considered to be one step ahead in the utilization of hydrogen as an alternative fuel source is because; Plant cells possess water-splitting enzymes

<h3>What are splitting Enzymes?</h3>

Splitting Enzyme’s are like aldolases that catalyze the conversion of a molecule into two smaller molecules without the addition or removal of any atoms.

Now in plant biology, plants make use of he light-driven water-splitting/oxygen-evolving enzyme known as Photosystem II in photosynthesis to split water.

Consider a hard disk with the following specifications :<br> 3.5 in diameter
AnnyKZ [126]

Answer:

usable capacity = 10 GB

Number of cylinders = 256

Block size = 4 KB

(1)Bytes in each cylinder = (10*230)/(256) = (10*222) = 40 MegaBytes

(2)Number of Blocks in each cylinder = (10*222)/(212) = 10K

(3)capacity of one track = 40 MegaBytes/(10*2) = 2 MB

Rotation speed = 3840 RPM

Number of rotations per second = 3840/60 = 64

Transfer rate = (2*64) = 128 MB/sec
