Answer:
I am attaching a file with the solution and explanation as the number character limit is exceeding.
Explanation:
Answer:
Δ enthalpy = -23 Btu/Ibm
Explanation:
Given data:
Pressure ( P1 ) = 250 psi
Initial Temperature ( T1 ) = 175°F
Final temperature ( T2 ) = 20°F
<u>Calculate the change in the enthalpy of R-134a </u>
From R-134 table
h1 = 129.85 Btu/Ibm
s1 = 0.23281 Btu/Ibm.R
note : entropy is constant
hence ; s1 = s2
by interpolation ; h2 = 106.95
Δ enthalpy = h2 - h1
= ( 106.95 - 129.85 ) = -23 Btu/Ibm
What are you asking? are you asking if it is true or false? sorry :(( i can help you tho!
Answer:
There is no "correct" name, but the scientific name could be meteorite.
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.
