The amplitude of the combined phasors is equal to 0° (0 degrees). This value is used in electricity.

A phasor is a complex number that describes the amplitude of a particular sinusoidal voltage and current.

In a phasor, the angular frequency, amplitude, and initial phase can be considered as time-invariant.

The angular frequency can be defined as the scalar measure of the rotation rate.

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

The received power if the effective aperture area of the receiving antenna is 20 m2 is 177.77 m2.

In physics, power is referred to as the rate of energy conversion or transfer over time. The unit of power in the SI system, often known as the International System of Units, is the Watt (W). A single joule per second is one watt.

Power was formerly referred to as activity in some research. A scalar quantity is power. As power is always a function of labor done, it follows that if a person's output varies during the day depending on the time of day, so will his power.

A measure of the pace at which energy is transferred, power is a physical quantity. As a result, it can be described as the pace of job completion relative to time.

Answer:

First, we need to calculate the volume of concrete needed to line the canal. The volume of a cylinder is given by the formula:V = πr^2hWhere V is the volume, r is the radius of the cylinder, and h is the height (length) of the cylinder.Since we are lining a canal, the cross-sectional shape of the canal is a rectangle, not a circle. However, we can still use the formula for the volume of a cylinder by treating the width of the canal as the radius and the height of the canal as the length.In this case, the width of the canal is w and the height is h, so the volume of the concrete needed to line the canal is:V = πw^2hWe are given that the length of the canal is 227 ft, so h = 227 ft. We are not given the width of the canal, so we cannot use the formula to calculate the volume of concrete needed.Next, we need to calculate the volume of concrete needed with the 12% allowance for waste and overexcavation. The volume of concrete needed with the allowance is the original volume plus 12% of the original volume.The volume of concrete needed with the allowance can be calculated using the following formula:V' = V + (V * 12%)Where V' is the volume of concrete needed with the allowance and V is the original volume.Since we do not know the original volume, we cannot use this formula to calculate the volume of concrete needed.To solve this problem, we need to know the width of the canal in order to calculate the volume of concrete needed. Without this information, it is not possible to determine the volume of concrete that must be delivered.

The forces acting on a child on a merry-go-round include centripetal force, gravitational force, and frictional force.

When a child is on a merry-go-round, several forces come into play. The first force is the centripetal force, which is responsible for keeping the child moving in a circular path. This force acts towards the center of the merry-go-round and is necessary to counterbalance the outward centrifugal force. It is generated by the contact between the child and the merry-go-round.

The second force is the gravitational force, which acts vertically downwards towards the center of the Earth. This force pulls the child towards the ground and determines their weight. Even though the child is in motion, the gravitational force remains constant and acts independently of the circular motion.

Lastly, there is the frictional force. This force occurs between the child and the surface of the merry-go-round. It opposes the child's motion and is necessary to provide the necessary traction to prevent slipping. Without friction, the child would not be able to stay on the merry-go-round and would slide off due to the centrifugal force.

Explanation:

True stress ( psi )       True strain

49300                          0.11

61300                           0.21

Determine the true stress necessary to produce a true plastic strain of 0.25

бT1 = 49300

бT2 = 61300

бT3 = ?

∈T1 = 0.11

∈T2 = 0.21

∈T3  = 0.25

note : бTi = k ∈Ti^h

∴ 49300 = k ( 0.11 )^h ----- ( 1 )

   61300 = k ( 0.21)^h ------ ( 2 )

solving equations 1 and 2 simultaneously

49300/61300 = ( 0.11 / 0.21 )^h

0.804 = (0.52 )^h

next step : apply logarithm

log  ( 0.804 ) = log(0.52)^h

h = log 0.804 /  log (0.52)

  =  0.33

back to equation 1

49300 = k ( 0.11 )^0.33

k = 49300 / (0.11)^0.33

 = 102138

therefore бT3 = K (0.25)^h

                        = 102138 ( 0.25 )^ 0.33  

                         = 64640.92

Here is a Java program that accomplishes the given tasks:

import java.awt.*;

import java.awt.geom.AffineTransform;

public class ShapeReflection {

   public static void main(String[] args) {

       // Reflecting the shape with the points

       int[] xPoints = {160, 220, 220, 190, 160};

       int[] yPoints = {130, 130, 160, 180, 160};

       int numPoints = xPoints.length;

       // Reflecting the shape about the line Y = -X + 500

       for (int i = 0; i < numPoints; i++) {

           int x = xPoints[i];

           int y = yPoints[i];

           // Calculate the reflected points

           int newX = 500 - y;

           int newY = 500 - x;

           // Update the original points with the reflected points

           xPoints[i] = newX;

           yPoints[i] = newY;

       }

       // Drawing the shape using loop and methods

       DrawingPanel panel = new DrawingPanel(600, 600);

       Graphics2D g2 = panel.getGraphics();

       g2.setColor(Color.BLACK);

       g2.drawPolygon(xPoints, yPoints, numPoints);

   }

}

This program uses the `java.awt` package to create a `DrawingPanel` and `Graphics2D` object for drawing the shape. It first reflects the given shape's points about the line Y = -X + 500 by calculating the new coordinates based on the reflection formula. Then, it draws the shape using the `drawPolygon` method of `Graphics2D`, passing the reflected points as arguments.

Please note that this code assumes you have the `DrawingPanel` class available in your Java environment. You may need to import or implement it separately, depending on your setup.
