Answer:
Java program given below
Explanation:
import java.util.Scanner;
public class LeapYearCheck {
public static void main(String[] args) {
Scanner in=new Scanner(System.in);
while(true)
{
System.out.print("Enter a year (0 to stop): ");
int year=in.nextInt();
// System.out.println();
if(year==0)
{
System.out.println("Bye.");
break;
}
boolean leap = false;
if(year % 4 == 0)
{
if( year % 100 == 0)
{
if ( year % 400 == 0)
leap = true;
else
leap = false;
}
else
leap = true;
}
else
leap = false;
if(leap)
System.out.println(year + " is a leap year.");
else
System.out.println(year + " is not a leap year.");
}
}
}
Answer:
The heat loss rate through one of the windows made of polycarbonate is 252W. If the window is made of aerogel, the heat loss rate is 16.8W. If the window is made of soda-lime glass, the heat loss rate is 1190.4W.
The cost associated with the heat loss through the windows for an 8-hour flight is:
For aerogel windows: $17.472 (most efficient)
For polycarbonate windows: $262.08
For soda-lime glass windows: $1,238.016 (least efficient)
Explanation:
To calculate the heat loss rate through the window, we can use a model of heat transmission by conduction throw flat wall. Using unidimensional Fourier law:
In this case:
If we replace the data provided by the problem we get the heat loss rate through one of the windows of each material (we only have to change the thermal conductivities).
To obtain the thermal conductivity of the soda-lime glass we use the graphic attached to this answer (In this case for soda-lime glass k₃₀₀=0.992w/m·K).
To calculate the cost associated with the heat loss through the windows for an 8-hour flight we use this formula (using the heat loss rate calculated in each case):
The elevation difference between the PVC and the high point on the curve 0.1208 ft
<u>Explanation:</u>
g1 = 4.0%
= 0.04
The elevation of curve at a distance “x”from pvc is given by
x = distance from pvc to point on curve
The highest point on vertical curve is at a distance "x" is given by
so, elevation of highest point
here,
substitute above values in "y" equation,
Algebric sum of grades = A =
As per AASHTO,for V= 60 mph, K =151 based on Stopping sight distance
Minimum length of vertical curve
We know that,
solving above equation we get, elevation distance between highest point and pvc as 0.1208 ft
Answer:
1. Low power hand tools/small
2. Light to medium industrial tools
3. Large industrial tools
There are definitely a lot more categories than three, but this is what I have.
I believe it’s E. Not completely shure though
