Answer:
a) 
, b) 
Explanation:
a) The Coefficient of Performance of the Carnot Heat Pump is:
After some algebraic handling, the temperature of the cold reservoir is determined:
b) The heating load provided by the heat pump is:
Answer:
a) 280MPa
b) -100MPa
c) -0.35
d) 380 MPa
Explanation:
GIVEN DATA:
mean stress 
stress amplitude 
a) 
--------------1
-----------2
solving 1 and 2 equation we get
b) 
c)
stress ratio
d)magnitude of stress range
= 280 -(-100) = 380 MPa
Answer:
C. Multipoint fuel injection
Explanation:
A fuel injection system can be defined as a system found in the engine of most automobile cars, used for the supply of a precise amount of fuel or fuel-air mixture to the cylinders in an internal combustion engine through the use of an injector.
There are different types of fuel injection system and these includes;
I. Central-point injection.
II. Throttle (single point) body injection.
III. Gasoline direct injection.
IV. Multipoint (port) fuel injection.
Multipoint fuel injection is a type of fuel injection system that operates with fuel injectors located only in the intake manifold near each intake valve and sprays fuel toward the valve. As a result, it allows for the supply of a precise amount of fuel and as such creating a better air-fuel ratio for automobile cars.
Answer:
import java.util.*;
public class BarChart
{
public static void main(String args[])
{
int arr[]=new int[5];
Scanner sc=new Scanner(System.in);
for(int i=0;i<5;i++)
{
while(true){
System.out.println("Enter today's sale for store "+(i+1)+" (negative value not allowed)");
arr[i]=sc.nextInt();
if(arr[i]>0)
break;
}
}
System.out.println("SALES BAR CHART");
for(int i=0;i<5;i++)
{
System.out.println("Store "+(i+1)+": ");
for(int j=0;j<arr[i];j=j+100)
{
System.out.print("*");
}
System.out.println("");
}
}
}
The answer would be C.the compressed air line is normally left connected
