Answer:
1) 63.66 ohm
2) 188.49 ohm
Explanation:
Data provided in the question:
Part 1
Capacitance, C = 5μF = 5 × 10⁻⁶ F
Frequency = 500 Hz
Now,
Impedance =
or
Impedance =
or
Impedance = 63.66 ohm
Part 2
Inductance = 60 mH = 60 × 10⁻³ H
Frequency = 500 Hz
Now,
Impedance for an inductor = 2πfL
thus,
Impedance = 2 × π × 500 × 60 × 10⁻³
= 188.49 ohm
Answer:
See explaination and attachment for the program code and output
Explanation:
#include <iostream>
using namespace std;
int main()
{
char gender; //details for gender and checking
char ans;
do
{
cout<<"Gender (M or F): ";
cin>>gender;
switch(gender)
{
case 'M':
//cout<<"Male."<<endl;
break;
case 'F':
//cout<<"Female."<<endl;
break;
default:
cout<<"Wrong Gender. Please enter again (M or F): ";
cin>>gender;
}
int Weight,Height,Age; //declaration of variables
double bmr;
cout<<"Weight: ";
cin>>Weight;
cout<<"Height (in inches): ";
cin>>Height;
cout<<"Age: ";
cin>>Age;
//bmr calculations for male and female
if (gender = 'M')
{
bmr = 66 + (6.3 * Weight) + (12.9 * Height) - (6.8 * Age);
cout<<"He needs "<<bmr<<" to maintain his weight."<<endl;
cout<<"He needs to eat "<<(bmr/230)<< " candy bars in one day."<<endl;
}
else if (gender = 'F')
{
bmr = 655 + (4.3 * Weight) + (4.7 * Height) - (4.7 *Age);
cout<<"She needs "<<bmr<<" to maintain her weight"<<endl;
cout<<"She needs to eat "<<(bmr/230)<< " candy bars in one day."<<endl;
}
cout<< "Do you want to do another one>continue (Y/N): ";
cin >> ans;
}while(ans=='y'||ans=='Y');
cout<<"\n Thanks for using my BMR calculator. Good Bye!.";
return 0;
}

24Ω
<h2>Explanation:</h2>
When resistors are connected in parallel, the reciprocal of their combined resistance, when read with a DMM (Digital Multimeter - for measuring various properties of a circuit or circuit element such as resistance...) is the sum of the reciprocals of their individual resistances.
For example if two resistors of resistances R₁ and R₂ are connected together in parallel, the reciprocal of their combined resistance Rₓ is given by;
=
+
Solving for Rₓ gives;
=
------------------(i)
From the question;
Let
R₁ = resistance of first resistor = 40Ω
R₂ = resistance of second resistor = 60Ω
Now,
To get their combined or total resistance, Rₓ, substitute these values into equation (i) as follows;
=
=
= 24 Ω
Therefore, the total resistance is 24Ω
Answer:
The resulting strain is .
Explanation:
A specimen of copper having a rectangular cross section 15.2 mm × 19.1 mm
Force, F = 44,500 N
Th elastic modulus of Cu to be 110 GPa
The resulting strain is given by the formula as follows :
E is elastic modulus of Cu is are of cross section
So, the resulting strain is .
