Unfortunately, I cannot see the figure you referred to in your question. However, I can provide you with the general steps to solve the problem.

To determine the dimensions of the riser so that it will take 0.5 min longer to freeze than the casting itself, you can use Chvorinov's rule, which relates the solidification time of casting to its volume and surface area.

The formula for Chvorinov's rule is:

t = K(V/A)^n

where:

t = solidification time (min)

K = mold constant (min/in^2)

V = volume of casting (in^3)

A = surface area of casting (in^2)

n = a constant that depends on the shape of the casting

To apply Chvorinov's rule to the riser, you need to determine the volume and surface area of the casting and the riser. Then, you can set up two equations using Chvorinov's rule, one for the casting and one for the riser, and solve for the diameter and height of the riser.

Here are the general steps to solve the problem:

Determine the volume and surface area of the casting. You can do this by breaking down the casting into simple shapes (e.g., cylinder, cone, sphere) and calculating their volumes and surface areas.

Determine the volume and surface area of the riser. Since the diameter-to-length ratio is 1.0, the riser is a cylinder. The volume of a cylinder is V = πr^2h, and the surface area is A = 2πrh + 2πr^2, where r is the radius of the cylinder and h is the height.

Plug the values for the volume and surface area of the casting and the riser into Chvorinov's rule to set up two equations:

t_casting = K(V_casting/A_casting)^n

t_riser = K(V_riser/A_riser)^n + 0.5

Substitute the formulas for the volumes and surface areas into the equations and simplify.

Solve the two equations for the radius and height of the riser.

I hope this helps you to solve the problem. If you have any further questions or need additional assistance, please let me know.

The environmental event that significantly increased the visibility of industrial transportation safety is Exxon Valdez Accident.

Exxon Valdez oil leaked into Alaska's Prince William Sound on March 24, 1989. At Prince William Sound, at 12:04 in the morning, the Exxon Valdez, an oil supertanker owned by Exxon Shipping Company and bound for Long Beach, California, collided with the Bligh Reef, 1.5 miles west of Tatitlek, Alaska. Over the course of the following few days, 10.8 million US gallons of crude oil were spilled. After the Deepwater Horizon oil disaster in 2010, the Exxon Valdez oil spill ranks second in terms of oil released in U.S. waters. Prince William Sound is a remote area that can only be reached by boat, helicopter, or airplane, which complicated government and industry response operations and made it particularly challenging to put current response plans into action. Salmon, sea otters, seals, and seabirds all call this area home. A total of 1,300 miles of shoreline were eventually impacted by the oil from the Prudhoe Bay Oil Field, of which 200 miles were significantly or moderately oiled.

Answer:

D) AND gate.

Explanation:

Given that:

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print

These conditions are:

1. The printer's electronic circuits must be energized.

2. Paper must be loaded and ready to advance.

3. The printer must be "on line" with the microprocessor.

Now; if these conditions are met  the logic gate produces a HIGH output indicating readiness to print.

The objective here is to determine the basic logic gate used in this circuit.

Now;

For NOR gate;

NOR gate gives HIGH only when all the inputs are low. but the question states it that "a HIGH is generated and applied to a 3-input logic gate". This already falsify NOR gate to be the right answer.

For NOT gate.

NOT gate operates with only one input and one output device but here; we are dealing with 3-input logic gate.

Similarly, OR gate gives output as a high if any one of the input signals is high but we need "a HIGH that is generated and applied to a 3-input logic gate".

Finally, AND gate output is HIGH only when all the input signal is HIGH and vice versa, i.e AND gate output is LOW only when all the input signal is LOW. So AND gate satisfies the given criteria that; all the three conditions must be true for the final signal to be HIGH.

To reduce the warpage, maintain the hardness of the edge, and maintain some level of fracture toughness of the katana blade made from 1080 steel, I suggest Normalize the blade, Quench the blade and Temper the blade.

The heat treatment I suggest are:
1) Normalize the blade: This process involves heating the blade above its critical temperature and allowing it to cool in still air. This will help reduce warpage and refine the grain structure, improving the toughness of the blade.

2) Quench the blade: After normalizing, heat the blade again to its austenitizing temperature and then quench it rapidly in a suitable medium (e.g., water, oil, or air). This process will harden the edge of the blade and help maintain its hardness.

3) Temper the blade: Following quenching, the blade will be in a brittle state. To improve its toughness and reduce the risk of fracture, temper the blade by reheating it to a lower temperature and then allowing it to cool slowly. This process will help maintain a balance between hardness and toughness.

The pressure exerted by water at point A is 4.75 kN/m^2, or 4.75 kPa.

The specific weight of mercury is 13.6 times that of water. Given that the atmospheric pressure at point A is 15 cm and the height difference between points A and B (h2 - h1) is 30 cm, we can determine the pressure difference between the two points.

The specific weight of a fluid is the weight per unit volume of the fluid. In this case, the specific weight of water is denoted by γw, and the specific weight of mercury is denoted by γm. We can express the relationship between these two specific weights as:

γm = 13.6γw

Since the specific weight of a fluid is directly proportional to the pressure it exerts, we can write:

Pm = 13.6Pw

Where Pm is the pressure exerted by mercury and Pw is the pressure exerted by water.

Using the hydrostatic pressure equation, we can relate the pressure difference to the height difference:

Pw = γw * h1

Pm = γm * h2

Substituting the values and known relationships:

Pw = γw * h1 = 13.6 * γw * h2 = 13.6 * Pw

Simplifying the equation:

12.6 * Pw = 59.8 kN/m^2

Dividing both sides by 12.6:

Pw = 4.75 kN/m^2

Therefore, the pressure exerted by water at point A is 4.75 kN/m^2, or 4.75 kPa.

Please note that there is a discrepancy between the given atmospheric pressure (59.8 kN/m^2) and the calculated pressure of water (4.75 kN/m^2). It is possible that there was an error in the provided atmospheric pressure value or in the calculations.

Motor units are recruited in order according to their recruitment thresholds and firing rates. Recruitment thresholds are the minimum strengths of stimuli required to generate action potentials in the muscle fibers. When a muscle contracts, the motor units that have the lowest threshold are recruited first, and those that have a higher threshold are recruited later on.

The larger motor units, which consist of fast-twitch fibers, have a higher threshold for recruitment and are activated only when a higher force is required. This enables the muscles to generate an appropriate amount of force according to the demands of the task.

The order of recruitment of motor units is also influenced by their firing rates. The motor units that have a higher firing rate are recruited earlier in the contraction, while those that have a lower firing rate are recruited later on. This means that the faster motor units are activated first, and the slower motor units are activated later on.

Overall, the recruitment of motor units is a complex process that is influenced by various factors, including the strength of the stimulus, the size of the motor unit, and the firing rate of the motor unit. The order of recruitment ensures that the muscles can generate an appropriate amount of force according to the demands of the task.
