Substances A and B have retention times of 16.63 and 17.63 min, respectively, on a 30 cm column. An unretained species passes th
Svet_ta [14]

Answer:

The time required to elute the two species is 53.3727 min

Explanation:

Given data:

tA = retention time of A=16.63 min

tB=retention time of B=17.63 min

WA=peak of A=1.11 min

WB=peak of B=1.21 min

The mathematical expression for the resolution is:

Re_{s} =\frac{2(t_{B}-t_{A})}{W_{A}+W_{B} } =\frac{2*(17.63-16.63)}{1.11+1.21} =0.8621

The mathematical expression for the time to elute the two species is:

\frac{t_{2}}{t_{1}} =(\frac{Re_{B} }{Re_{s} } )^{2}

Here

ReB = 1.5

t_{2} =t_{1} *(\frac{Re_{B} }{Re_{s} } )^{2} =17.63*(\frac{1.5}{0.8621} )^{2} =53.3727min

Prompt the user to input an integer, a double, a character, and a string, storing each into separate variables. Then, output tho
Likurg_2 [28]

Answer:

See explanation

Explanation:

//Include the

//required header files.

#include <stdio.h>

//Define the

//main() function.

int main(void) {

//Declare the

//required variables.

char input_char;

int input_int;

double input_double;

char input_string[100];

//Prompt the user

//to enter an integer.

printf("Enter integer: ");

//Read and store

//the integer.

scanf("%d", &input_int);

//Prompt the user

//to enter a double value.

printf("Enter double: ");

//Read and store

//the double value.

scanf("%lf", &input_double);

//Prompt the user

//to enter a character.

printf("Enter character: ");

//Read and store

//the character.

scanf(" %c", &input_char);

//Prompt user to

//enter the string

printf("Enter string: ");

//Read and

//store the string.

scanf("%s", input_string);

//(1)

//Display the values.

printf("%d %lf %c %s\n",

input_int, input_double,

input_char, input_string);

//(2)

//Display the values

//in reverse order.

printf("%s %c %lf %d\n",

input_string, input_char,

input_double, input_int);

//(3)

//Cast the double to

//an integer and display it.

printf("%lf cast to an integer is %d",

input_double, (int)(input_double));

//Return from the

//main() function.

return 0;

What is the relationship between inductive reactance and frequency?
Masteriza [31]

Answer:

Inductive reactance is denoted by X_L where

X_L=2\pi fL

from looking at the equation, you can see that as frequency increases, so does the inductive reactance.

A multipurpose transformer has a secondary coil with several points at which a voltage can be extracted, giving outputs of 5.60,
WITCHER [35]

Answer:

Explanation:

A multipurpose transformer can act as step up as well as step down transformer according to the desired setting by a user.

When the voltage at the output is greater than the voltage at the input of the transformer then it acts as step-up transformer and vice-versa acting is a step down transformer.

Given that:

input (primary) voltage of the transformer, V_i=220~V

no. of turns in the primary coil, N_i=230

  • When the output voltage is 5.60 V:

V_o=5.60~V

\frac{N_i}{N_o} =\frac{V_i}{V_o}

\frac{N_o}{230}=\frac{5.60}{220}

N_o=5.85\approx 6 turns compensating the losses

  • When the output voltage is 12.0 V:

V_o=12.0~V

\frac{N_i}{N_o} =\frac{V_i}{V_o}

\frac{N_o}{230}=\frac{12.0}{220}

N_o=12.45\approx 13 turns compensating the losses

  • When the output voltage is 480 V:

V_o=480~V

\frac{N_i}{N_o} =\frac{V_i}{V_o}

\frac{N_o}{230}=\frac{480}{220}

N_o=501.8\approx 502 turns compensating the losses
