turtle man is 55 years old
Answer:
Explanation along with code and output results is provided below.
C++ Code:
#include <iostream>
using namespace std;
int main()
{
int year;
cout<<"Enter the car model year."<<endl;
cin>>year;
if (year<=1969)
{
cout<<"Few safety features."<<endl;
}
else if (year>=1970 && year<1989)
{
cout<<"Probably has seat belts."<<endl;
}
else if (year>=1990 && year<1999)
{
cout<<"Probably has antilock brakes."<<endl;
}
else if (year>=2000)
{
cout<<"Probably has airbags."<<endl;
}
return 0;
}
Explanation:
The problem was to print feature messages of a car given its model year.
If else conditions are being used incorporate the logic. The code has been tested with several inputs and got correct output results.
Output:
Enter the car model year.
1961
Few safety features.
Enter the car model year.
1975
Probably has seat belts.
Enter the car model year.
1994
Probably has antilock brakes.
Enter the car model year.
2005
Probably has airbags.
Answer:
a)W=12.62 kJ/mol
b)W=12.59 kJ/mol
Explanation:
At T = 100 °C the second and third virial coefficients are
B = -242.5 cm^3 mol^-1
C = 25200 cm^6 mo1^-2
Now according isothermal work of one mole methyl gas is
W=-
a=
b=
from virial equation
And
a=
b=
Now calculate V1 and V2 at given condition
Substitute given values = 1 x 10^5 , T = 373.15 and given values of coefficients we get
Solve for V1 by iterative or alternative cubic equation solver we get
Similarly solve for state 2 at P2 = 50 bar we get
Now
a=241.33
b=30780
After performing integration we get work done on the system is
W=12.62 kJ/mol
(b) for Z = 1 + B' P +C' P^2 = PV/RT by performing differential we get
dV=RT(-1/p^2+0+C')dP
Hence work done on the system is
a=
b=
by substituting given limit and P = 1 bar , P2 = 50 bar and T = 373 K we get work
W=12.59 kJ/mol
The work by differ between a and b because the conversion of constant of virial coefficients are valid only for infinite series
Answer:
The phase current in each line conductor are;
Explanation:
Given the following data;
Red phase = 24kW,
Yellow phase = 18kW
Blue phase = 12kW
Line voltage = 415V
For a star connected system, we have;
The phase sequence for RYB is given by;
<em>For the Red phase;</em>
<em>For the Yellow phase;</em>
<em>For the Blue phase;</em>
For the line neutral;
Substituting we have,
