b) If RL = 470 ohms, then VL = 10v, IL = 21.276mA, Ir = 45.45mA

c) The value of RL that will establish maximum power conditions for the            Zener diode, R\(_{L_{(max)}}\) = 1.83 kΩ

d) The minimum value of RL to ensure that the Zener diode is in the "on" state R\(_{L_{(min)}}\) = 220 Ω

A Zener diode is a particular kind of diode made to consistently permit current to flow "backwards" (with inverted polarity) when a specific reverse voltage, called the Zener voltage, is reached.

A wide range of Zener voltages, some of which are even variable, are used in the manufacture of Zener diodes. The reverse conduction occurs in some Zener diodes with sharp,  highly dopped p - n junctions and low Zener voltages; in these cases, the Zener effect, named after Clarence Zener, is caused by electron quantum tunneling in the small gap between the p and n regions.

Avalanche breakdown also occurs during the operation of diodes with higher Zener voltages, which have a more gradual junction.

Answer:

the third anwser is right on edgeinuity

Explanation:

Answer:

Technology can pull students’ focus away from their tasks.

Explanation:

Here, AND and OR operators are used. They are logical operators. The answer to part a: The result of the AND operation will be stored in $t2. Part b) The result of the OR operation will be stored in $t2.

(a) The first line of code adds the immediate value of 0xFF2B to the register $t0. The $zero in the instruction is a placeholder for the value 0, which means that the value of 0xFF2B will be stored directly in $t0. The second line of code performs an AND operation between the value in $t2 and $t0. Since $t2 is not initialized to any value before this code segment, the outcome of this operation will depend on the previous value of $t2. The result of the AND operation will be stored in $t2.

(b) The code segment performs an OR operation between the value in $t2 and the immediate value of 0x00E9. The OR operation combines the bits of the two operands, where the result is set to 1 if either of the corresponding bits in the operands is 1. The outcome of the OR operation will depend on the previous value of $t2. The immediate value of 0x00E9 will remain constant. The result of the OR operation will be stored in $t2.

Answer:

a) 0.645%

b) 4.046%

c) Seawater is highly incompressible and the air is much more compressible

Explanation:

a)

First we take a look at BULK MODULUS;

change in pressure is expressed as;

dp = -K(dV/V)

bulk modulus K = 2.28*10^9 N/m^2 for seawater

now one atm is given as;

1 atm = 101325 N/m^2

by conversion factor,

1 atm = 10.3m equivalent in height of water

now writing this pressure in terms of equivalent height of water at 1500m

we say;

dp = 1500/10.3 * 101325 N/m^2  

now substituting into dp = -K(dV/V)

dV/V = - dp/K

= - ( 1500/10.3 * 101325 N/m^2  ) / (2.28*10^9 N/m^2)

=  - (14756067.96 / 2.28*10^9)

= - (0.00647)

= - 0.645%

the fractional change in volume of fixed mass of seawater is 0.645%, the negative sign indicates the decrease in the change in volume.

b)

Lets look at the ideal gas equation

pV = mRT

P = pRT

now we know that T and T are constant

dP = RTdp

so

dP/P = dp/p

given that the equivalent change in the pressure is 4100 Pa;

dp/p = 4100 / 101325

= 0.04046

= 4.046%

the fractional change in density of a fixed mass of air is 4.046%

c)

Taking a close look of the fractional change in volume of seawater in partA and the fractional change in density of a fixed mass of air in partB, we can say that Seawater is highly incompressible and the air is much more compressible.

Answer:

The power needed to drive this pump assuming  and efficiency of 75% is 1874.0 watts (W)

Explanation:

Solution:

Given that:

Velocity  = 2 m/s

Pressure = 100 kPa

The pump exit is =4 m

Efficiency 75%

Thus,

We apply the method called the Bernoulli's equation between two reservoirs

p₁ / ps + v₁²/2g + z₁

=p₂/ps/v₂²/2g +z₂ + hL

The density of gasoline (pg) is = 680 kg m³

The gravity of acceleration is known to be  =9.81 m/s²

So,

100/680 *9.81 + 2²/2 *9.81 + 1 = 500/ 680 * 9.81 + 3²/2 * 9.81 +4 + hL

16. 2 = 79.41 + hL

hl =79.41 - 16.2

hL =63.21 m

the unit weight of gasoline is(γ) = 680 * 9.81 = 6670.8 m/s

Now we find the efficiency

The efficiency  (η) = The output power /Input power

Where hL =H

The input power = γ * Q * H/0.75

=6670.8 *12/3600 * 63.21

=6670.8 * 0.333 * 63.21

=6670.8 *0.2107

=1405.5/0.75

The input power =1874.0 Watts

In order to achieve a full 20,000lbs support rating for a 12' t-spot shore made from 6x6's, the header and sole plate should be sized appropriately.

The exact size required will depend on several factors such as the species of wood, the moisture content, and the specific load conditions. Generally speaking, a header made from two 2x12's and a sole plate made from two 2x8's or one 2x12 should be sufficient.

The use of hexadecimal (hex) as a shorthand representation for binary numbers is more common today than octal (oct) because hex requires fewer digits than oct to represent a binary number. Additionally, hex can more compactly represent an 8-bit (1-byte) binary number than oct.

Hexadecimal is a base-16 numbering system that uses 16 symbols to represent a number. It consists of 0–9 digits, followed by A–F letters, where A represents 10 and F represents 15. For instance, the hex number 1A is equal to the decimal number 26.

On the other hand, Octal is a base-8 numbering system that uses eight symbols to represent a number. It consists of digits from 0 to 7. For example, the octal number 25 is equal to the decimal number 21.

Given that a byte value is 11111111, we can convert it into both octal and hexadecimal format using the following steps:

To convert to Octal format, we must first split the given 8-bit (1-byte) binary number into groups of three from right to left. If the number of bits is not divisible by 3, add zeroes on the left. In this case, 111 11111 is the result. Next, write the octal digit corresponding to each group of three from right to left. Thus, 111 11111 → 377. Therefore, the octal representation of 11111111 is 377.

To convert to Hexadecimal format, we must first split the given 8-bit (1-byte) binary number into groups of four from right to left. If the number of bits is not divisible by 4, add zeroes on the left. In this case, 1111 1111 is the result. Next, write the hexadecimal digit corresponding to each group of four from right to left. Thus, 1111 1111 → FF. Therefore, the hexadecimal representation of 11111111 is FF.

Thus, the number 11111111 in octal format is 377 and in hexadecimal format is FF.

The process of joining metal parts using an electric arc is known as Arc welding. This process is the most extensively used welding process that involves the use of an electric arc to melt the base material and filler material to combine them. The electric arc burns between the electrode and the workpiece, producing intense heat.

An electric current is passed through an electrode to produce an arc which melts the metal at the welding point. An electrode is a metal rod with a coating that melts along with the metal. It offers the filler metal and flux that secures the weld from oxidation and other pollutants. It is a simple welding process that is used in the production of structures and construction projects.  Each type of welding process has its advantages and disadvantages. The type of welding process selected depends on the thickness of the material, the type of metal, and the desired weld joint. Arc welding has high power consumption and requires the welder to be skilled in the welding process.
