ACL access will be revoked in the future aws redshift

Answers

Answer 1

A security precaution that may be used to make sure that only authorized users can access the Redshift cluster is revoking ACL (Access Control List) access in AWS Redshift.

How to explain the information

It should be noted that to prevent any potential security problems, it's always a good idea to evaluate and change the permissions given to users on a regular basis.

You should speak with the Redshift cluster owner or the administrator of your AWS account to learn the reasoning behind any potential revocation of your ACL access.

In any event, make sure you have a backup method of getting to the Redshift cluster. You can use IAM (Identity and Access Management) roles, which offer a more fine-grained level of access control, to request the AWS account administrator to grant you the necessary permissions.

Explanation:

The volume of fuel being returned to the tank is being discussed. Technician A says that it is normal for a small amount of fuel to be returned to the tank by the high-pressure pump and the injectors. Technician B says that any fuel being returned to the tank by the high-pressure pump or the injectors is an indication of a problem. Which technician is correct

Answers

Technician A is correct. The high-pressure pump and the injectors are expected to return a little amount of fuel to the tank. The term "fuel return" or "fuel recirculation" refers to this.

To maintain proper fuel pressure and circulation, many fuel systems return a part of the fuel that is not injected into the engine to the fuel tank. This lessens vapour lock and cools the injectors.

The fuel return system's main functions are to control fuel pressure and guarantee the fuel system's effective operation. Without fuel return, the fuel system could become overly pressurized, which could result in damage or failure.

4. On wet roads, the chance of hydroplaning increases with the increase of speed.
True
False

Answers

Answer:

The answer to the question is True

On wet roads, the chance of hydroplaning increases with the increase of speed. Thus, the given statement is true.

During rainy weather, roads may become slippery and difficult to drive on. Slippery roads may also arise as a result of snow or ice. The fact that the road surface has less traction than normal is what makes it slippery. On slippery roads, it is recommended that drivers slow down to reduce the risk of skidding, sliding, or losing control of their cars, especially when taking turns.

Drivers should also increase their following distance and avoid abrupt braking or accelerating. Drivers should not drive faster than 25 mph on slippery roads, and they should not increase their speed to avoid hydroplaning. Instead, drivers should slow down.

A Piper Cub airplane has a gross weight of 1700 lb, a cruising speed of 114 mph, and a wing area of 178 ft^2. Determine the lift coefficient of this airplane for these conditions.

Answers

Solution :

As the plane is flying in the air, the force of weight is pulling the plane down. This force must be equal to the force of lift which is generated from the plane's translation true the air. Therefore, the next condition must be satisfied.

\($F_W= L $\)  ................. (i)

The lift force of the plane is given by :

\($L=C_V \frac{\rho}{2} V^2 A$\)

Since the weight force of the plane is given, from the condition (i), we also know the intensity of the lift force.

Therefore, we transform the lift force expression to derive the lift coefficient formula:

\($C_L=\frac{2L}{\rho V^2 A}$\)

\($C_L=\frac{2 \times 1700}{2.38 \times 10^{-3 }\times (167.2)^2 \times 178} $\)

\($C_L = 0.287$\)

a) the starting torque generated by the motor just as the voltage is applied.
b) the maximum speed at a torque of zero.
c) the operating point of the motor when it is connected to a load whose torque characteristic is proportional to speed with a constant of proportionality = 0.0125 N-m/(rad/sec).

Answers

Answer:

The answer is below

Explanation:

Given that:

\(k_t=torque\ constant=0.075\ Nm/A\\\\k_v=voltage\ constant=0.12\ V/(rad/sec)\\\\R_a=armature \ resistance=2.5 \Omega\\\\V_t=terminal\ voltage=24\ V\\\\a)The \ starting\ current\ I_a\ is\ given \ as:\\\\I_a=\frac{V_t}{R_a} =\frac{24}{2.5} =9.6\ A\\\\The \ starting\ torque(T)\ is:\\\\T=k_tI_a=0.075*9.6=0.72\ N.m\)

b) The maximum speed occurs when the terminal voltage and back emf are equal to each other i.e.

\(V_t=e_b=k_v\omega\\\\\omega=\frac{V_t}{k_v}=\frac{24}{0.12} =200\ rad/s\)

c) The load torque is given as:

\(T_L=0.0125\Omega\\\\The\ motor\ torque \ is:\\\\T=k_t(\frac{V_t-k_v\omega}{R_a} )\\\\but\ T = T_L,hence:\\\\0.0125\omega=0.075(\frac{24-0.12\omega}{2.5} )\\\\0.03125\omega=1.8-0.009\omega\\\\0.04025\omega=1.8\\\\\omega=44.72\ rad/sec\\\\N=\frac{60\omega}{2\pi} =\frac{60*44.72}{2\pi} =427\ rpm\)

True is the correct answer.

The airstream should penetrate or come between the base metal and the electrode from the back during the CAC-A operation.

How does CAC-A process works-The molten metal will first travel a great distance due to the air blast. Front of the gouging operation should have metal deflection plates.The airstream should penetrate between the base metal and the electrode from the back during the CAC-A operation. All combustible materials should be removed from the work area. If not properly contained, the mass of molten metal extracted at high current levels, which is rather significant, will become a fire danger.The second element is the loud noise. A very loud noise happens when there are strong currents and strong air pressure. Arc cutters ought to use ear protection, ear muffs, or earplugs. The air carbon arc cutting procedure (CAC) is used to cut metal, gouge out damaged metal, remove outdated or subpar welds, prepare grooves for welding, and root gouge full penetration welds.When slightly ragged edges are acceptable, air carbon arc cutting is also employed.Metals are joined using it as well.

That is, what are the chances that A is not is the 1st position, nor is B in the 2nd position, nor is C in the 3rd position, nor is D in the 4th position, nor is E in the 5th position

Answers

The probability that none of the letters A, B, C, D , and E is in the correct position is 11/30

How to find the probability that none of the letters are on the right position

probability that none of them is in the right position

= 1 - Probability they are in right positions

probability is solved with the formula

= required outcome / total outcome

5 letters can be arranged in 5! ways, hence total outcome

= 5!

= 5 * 4 * 3 * 2 * 1

= 120 ways

There is 5 required outcome of positioning the letters right

1. chance that all the letters are in the right position = 1

2. chance that 4 of the letters are in the right position = 0

This is zero because it is same as the first. If 4 are in the right position the all are in the right position.

3. chance that 3 of the letters are in the right position

= ⁵C₃ * 1

= 10

4. chance that 2 of the letters are in the right position

= (⁵C₂) * 2

= 10 * 2

= 20

5. chance that 1 of the letters are in the right position

= (⁵C₁) * 9

= 5 * 9

= 45

sum of the outcomes = 76

probability = required outcome / total outcome

= 76/120

A series resistive circuit has two resistors. R1 is 570 ohms and R2 is 560 ohms.
The total circuit current is 17.9 milliamps.
Find the voltage drop across R1 in volts.

Answers

Answer:

10.203 Volts

Explanation:

For this problem, we need to understand that a series resistive circuit is simply a circuit with some type of voltage source and some resistors, in this case, R1 and R2.

First, we need to find the voltage in the circuit.  To do this, we need to find the total resistance of the circuit.  When two resistors are in series, you sum the resistance.  So we can say the following:

R_Total = R1 + R2

R_Total = 570 Ω + 560 Ω

R_Total = 1130 Ω

Now that we have R_Total for the circuit, we can find the voltage of the circuit by using Ohm's law, V = IR.

V_Total = I_Total * R_Total

V_Total = 17.9 mA * 1130 Ω

V_Total = 20.227 V

Now that we have V_Total, we can find the voltage drop across each resistor by using Ohm's law once more.  Note, that since our circuit is series, both resistors will have the same current (I.e., I_Total = I_1 = I_2).

V_Total = V_1 + V_2

V_Total = V_1 + I_2*R2

V_Total - I_2*R2 = V_1

20.227 V - (17.9 mA * 560 Ω) = V_1

20.227 V - (10.024 V) = V_1

10.203 V = V_1

Hence, the voltage drop across R1 is 10.203 Volts.

Cheers.

Which of the following is an implication of low
variety?
A. low unit cost
B. flexibility needed
C. high complexity
D. matching customers specific needs
PLEASE EXPLAIN WHICH IS CORRECT WITH EXPLANATION

Answers

The correct option for the implication of low variety is B) Flexibility needed. Variety refers to the number of different products, services, or activities that an organization offers. High variety means that a company offers a wide variety of products or services, while low variety means that a company provides a limited range of products or services.

One of the implications of low variety is that customers have limited options. They are restricted to purchasing only those goods and services that the company offers, which may not match their requirements or preferences. This may lead to losing customers to rivals who offer a greater variety of goods and services.

In the case of low variety, it is critical to have the required flexibility. Customers may ask for certain specific goods or services that are not provided by the company. To meet customer requirements, the company should be adaptable and able to rapidly respond to customer requests by expanding its product line. As a result, low variety necessitates the need for flexibility.

The other given options are not valid. Low unit cost is not related to low variety. Unit cost may be affected by economies of scale and other factors, but it is not directly related to variety. High complexity is not related to low variety as well. As the range of goods and services offered by the company increases, the complexity of the company's operations and management also increases. Matching customers' specific needs is partially correct because the company cannot match customer specific needs in low variety. In low variety, the company has a limited range of goods and services, so it is not possible to fulfill all the customers’ specific needs.

A deep drawing operation is performed on a sheet-metal blank that is 1/8 in thick. The height of the cup = 3.8 in and its diameter = 5.0 in (both inside dimensions). (a) Assuming the punch radius = 0, compute the starting diameter of the blank to complete the operation with no material left in the flange. (b) Is the operation feasible (ignoring the fact that the punch radius is too small)?

Answers

Answer:

a) Db = 10.05 in

b) The operation is not feasible

Explanation:

Let's begin by listing out the given variables:

Thickness = 1/8 in, Height (h) = 3.8 in,

Diameter (Dp) = 5 in ⇒ rp = Dp ÷ 2 = 5 ÷ 2 = 2.5 in

a) Area of cup = Area of wall + Area of base

A = 2πh(rp) + π(rp)²

A = (2π * 2.5 * 3.8) + (π * 2.5²)

A = 59.69 + 19.635 = 79.325 in²

A ≈ 79.33 in²

But π(rb)² = 79.33 ⇒ rb² = 79.33 ÷ π

rb² = 25.25

rb = 5.025 ⇒ Db = 2 * rb = 2 * 5.025 = 10.05 in

Db = 10.05 in

b) To calculate for feasibility, we use the formula, draw ratio equals diameter of the blank divided by diameter of the punch

Mathematically,

DR = Db ÷ Dp

DR = 10.05 ÷ 5 = 2.01

DR = 2.01

DR > 2 ⇒ the operation is not feasible

For an operation to be feasible, it must have a drawing ratio limit of 2 or lesser

Answers

To determine the largest force that can be exerted by the press, knowing that the allowable stress in section A-A is 75 MPa, follow these steps:

Step 1: Identify the allowable stress
The allowable stress in section A-A is given as 75 MPa (megapascals).

Step 2: Determine the area of section A-A
To find the force, you need to know the area of the section A-A. This information should be provided in the problem statement or the diagram of the press. If the area is not given, you will need to calculate it using the dimensions of section A-A (e.g., if it's a circular or rectangular section).

Step 3: Calculate the maximum force
Use the formula: Force = Allowable Stress x Area
Substitute the given values into the formula: Force = 75 MPa x Area of section A-A

Step 4: Convert the force to the appropriate unit
If necessary, convert the force from newtons (N) to another unit (e.g., pounds, kilonewtons, etc.), depending on the context of the problem.

The largest force that can be exerted by the press is the result obtained from the calculation in Step 3.
