What are the differences between convex lens and convex mirrors ?

The force that is not a fundamental force is the frictional force.

In physics, there are four fundamental forces that govern the interactions between particles: gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force.

The gravitational force is responsible for the attraction between objects with mass. It is the force that keeps planets in orbit around the sun and holds us to the Earth's surface.

The electromagnetic force is responsible for interactions between charged particles. It is the force that allows magnets to attract or repel each other and is involved in the behavior of electric currents.

The strong nuclear force holds atomic nuclei together. It is the force that overcomes the electrostatic repulsion between protons in the nucleus and keeps the nucleus stable.

The weak nuclear force is involved in certain types of radioactive decay. It is responsible for processes such as beta decay, where a neutron in an atomic nucleus transforms into a proton, an electron, and an electron antineutrino.

Out of the options given, the force that is not a fundamental force is the frictional force. Frictional force is a contact force that opposes the relative motion or tendency of motion between two surfaces in contact. It is not considered a fundamental force because it arises from the interactions between atoms and molecules at the microscopic level.

Explanation:

The load diagram for a 40D ocean container with 101010-inch boxes, assuming a 40*48 inch pallet that is 6 inches tall, can accommodate approximately X number of boxes.

To calculate the load diagram, we need to consider the dimensions of the container, pallet, and boxes, as well as their weights. The internal dimensions of a 40D ocean container are typically around 39'6" in length, 7'8" in width, and 7'10" in height.

First, let's calculate the number of pallets that can fit on the container floor. Since the pallet dimensions are 40*48 inches, we divide the container's width (7'8" or 92 inches) by the pallet width (48 inches). This gives us approximately 1.92, so we can fit 1 pallet in the width direction.

Next, we divide the container's length (39'6" or 474 inches) by the pallet length (40 inches) to find that we can fit approximately 11.85 pallets in the length direction. However, since the 40D container is not long enough to accommodate 12 full pallets, we can only fit 11 pallets in this direction.

Considering the height, we need to account for the 6-inch tall pallet as well as the 10-inch tall boxes. Since the container's height is 7'10" (or 94 inches), we subtract the combined height of the pallet and boxes (6 + 10 = 16 inches) from the container's height. This gives us 94 - 16 = 78 inches available for stacking.

Finally, we multiply the number of pallets (11) by the number of boxes that can be stacked (7) to find the total number of boxes that can fit in the container: 11 * 7 = 77 boxes. Therefore, the load diagram for a 40D ocean container with 101010-inch boxes and a 40*48-inch pallet that is 6 inches tall can accommodate approximately 77 boxes.

Analyze system dynamics and design compensator to achieve desired response by selecting compensator zero and canceling one pole of GHP(z).

To select a compensator zero to cancel one pole of GHP(z), we need to use the given angle condition:

Zzero - (pole(1) + Zpole(B)) = 180°

Here, Zzero represents the compensator zero, pole(1) represents the first pole of GHP(z), and Zpole(B) represents the compensator pole.

Let's proceed with the solution step by step:

1. First, we need to determine the value of Zzero. The angle condition states that Zzero = Zpole(1), which means the compensator zero is equal to the first pole of GHP(z).

2. Now, we need to find the value of Zpole(B). We can rewrite the angle condition as follows:

Zpole(B) = Zzero - pole(1) + 180°

Since we already know that Zzero = Zpole(1), we can substitute Zzero in the above equation:

Zpole(B) = Zpole(1) - pole(1) + 180°

Simplifying further:

Zpole(B) = 180°

Therefore, the value of Zpole(B) is 180°.

To summarize, we can select the compensator zero (Zzero) to cancel one pole of GHP(z) as Zpole(1), and the compensator pole (Zpole(B)) is determined to be 180° based on the given angle condition.

Machines can make work easier by trading off force for distance. For instance, by extending the distance across which the force is delivered, a lever can be utilized to raise a heavy object with less force.

The short end of the lever receives the input force, and the long end receives the output force. Although it functions across a wider area, the output force is smaller than the input force. This makes it easier for the user to lift the bulky object.

Answer:

A. 1st law.

Explanation:

Newton's first law of motion states that, an object or body will continue to be at rest or experience a uniform motion in a straight line at constant speed provided there's no action of an external force. Thus, unless compelled to change its state by an external force, a body will continue to be at rest or experience a uniform motion in a straight line.

The Newton's first law of motion is also known as the law of inertia; which is the tendency of a body to be at rest unless acted upon by an external force.

In this scenario, you are standing in a subway train and the train suddenly stops but your body continues to move forward. This is in accordance with Newton's first law of motion.

Hence, the sudden stoppage of the train generates a force which acts on the body thereby causing the passenger to tip or move forward.

Given information: The average method reports the following unit data for the forming department. Units completed in the forming department are transferred to the painting department. Production cost information for the forming department follows.

Direct materials:
Units completed during the period = 45,000 units
Ending work in process inventory = 5,000 units
Direct materials cost = $202,500

Conversion costs:
Units completed during the period = 45,000 units
Ending work in process inventory = 5,000 units
Conversion cost = $189,000

a. Calculation of equivalent units of production for both direct materials and conversion for the forming department:
Equivalent units of production = Units completed during the period + (Ending work in process inventory * Degree of completion)
Direct materials:
Equivalent units of production = 45,000 + (5,000 * 50%) = 47,500 units

Conversion costs:
Equivalent units of production = 45,000 + (5,000 * 60%) = 48,000 units

b. Calculation of the cost per equivalent unit of production for both direct materials and conversion for the forming department:
Cost per equivalent unit of production = Total cost for the period / Equivalent units of production

Direct materials:
Cost per equivalent unit of production = $202,500 / 47,500 units = $4.26 per unit

Conversion costs:
Cost per equivalent unit of production = $189,000 / 48,000 units = $3.94 per unit

c. Calculation of the cost assigned to the forming department's output using the weighted average method:
Total cost = Cost of units transferred out + Cost of ending work in process inventory
Cost of units transferred out = Number of units transferred out * Cost per equivalent unit of production
Cost of ending work in process inventory = Number of units in ending work in process inventory * Cost per equivalent unit of production

Direct materials:
Cost of units transferred out = 40,000 * $4.26 per unit = $170,400
Cost of ending work in process inventory = 5,000 * $4.26 per unit = $21,300
Total cost = $170,400 + $21,300 = $191,700

Conversion costs:
Cost of units transferred out = 40,000 * $3.94 per unit = $157,600
Cost of ending work in process inventory = 5,000 * $3.94 per unit = $19,700
