Explanation:
Thermodynamics system :
Thermodynamics system is a region or space in which study of matters can be done.The system is separated from surroundings by a boundary this boundary maybe flexible or fixed it depends on situations.The out side the system is called surroundings.
Generally thermodynamics systems are of three types
1.Closed system(control mass system)
Only energy transfer take place ,no mass transfer take place.
2.Open system(control volume system)
Both mass as well as energy transfer take place.
3.Isolated system
Neither mass or nor energy transfer take place.
At steady state ,property is did not changes with respect to time.
If a clock frequency is applied to a cascaded counter, The lowest output frequency available will be
- The lowest output frequency will be =
<h3>
Cascade Counter</h3>
For a cascade counter,
Overall frequency = 
Overall frequency = 
<h3>Lowest F
requency</h3>
Therefore,
the lowest frequency

Answer:
The following program is in C++.
#include <bits/stdc++.h>
using namespace std;
void lastChars(string s)
{
int l=s.length();
if(l!=0)
{
cout<<"The last character of the string is: "<<s[l-1];
}
}
int main() {
string s;//declaring a string..
getline(cin,s);//taking input of the string..
lastChars(s);//calling the function..
return 0;
}
Input:-
Alex is going home
Output:-
The last character of the string is: e
Explanation:
In the function lastChars() there is one argument that is a string.I have declared a integer variable l that stores the length of the string.If the length of the string is not 0.Then printing the last character of the string.In the main function I have called the function lastChars() with the string s that is prompted from the user.
Answer:
a. 430.944 pascal
b. 0.0625psi
c. 1.73008inH20
Explanation:
The pressure rise Ap associated with wind hitting a win- dow of a building can be estimated using the formula Ap-p(12/2), where p is density of air and V is the speed of the wind. Apply the grid method to calculate pressure rise for P-1.2 kg/m and V-60 mph. a. Express your answer in pascals. b. Express your answer in pounds-force per square inch (psi). c. Express your answer in inches of water column
checking the dimensional consistency
Dp=
convert 1 mile to meter
1mile=1609m
1h=3600s
60mile/h=26.8m/s
slotting intpo the relation
430.944kg/(ms^2)
which is the same as 430.944N/m^2
expressing in pascal.
We know that
1 pascal=1 N/m^2
430.944 pascal
2. 1 pascal=0.000145psi
answer=0.0625psi
3.1 pascal=0.00401inH20
answer=430.944*0.0040146
1.73008inH20
