How does Allure of the Seas make Titanic look in size?

The Allure is 298 feet longer than the Titanic and 197,999 tons heavier. She has 16 passenger decks compared to Titanic's 9

What are MACROS in 8086 microprocessors?

Macro is a segment of code that needs to be written only once but whose basic structure can be repeated with each reference

What is the size of 10 drums water tank?

A standard, 55 US gallon / 44 Imperial gallon drum would lead me to believe you would have a 550 US Gallon tank.

How does using a transistor with a different beta affect the operation of the common emitter amplifier?

Gain, in the common emitter amplifier, is beta (hFe) or collector resistance divided by emitter resistance, whichever is less. Substituting a different beta (hFe) transistor will affect gain, if hFe is less, or increase stability and design margin, if hFe is greater.

What are the advantages of photochromic pain?

you were wearing photochromatic sunglasses then you would not have had to take off and then put on your sunglasses. The lenses would have reacted to the change in light conditions and would keep your eyes well protected throughout your journey.

A photochromatic lens will only alter in the area subjected to change in light, therefore if only one part of peripheral vision is subjected to an increase in light intensity then only that part will change. Every area of the lens is fully independent from all other areas.

What is the difference between a Mac and an UZI?

Uzi has a high fire rate, and Mac has more accuracy but less fire rate

Why do mobile phone shops always stay in the same place?

Because they have a steady customer stream ! The shops sell the handsets.. and supply all sorts of accessories, batteries, cases etc.

What is called the winding around the CRT yoke that deflects the electron beam with its magnetic field?

It's called a deflection coil. If a c.r.t. uses magnetic deflection, there will be two deflection coils, a horizontal one and a vertical one.

What is dimensions of coulomb?

Current is rate of flow of charge, so 1 ampere = 1 coulomb per second.

As ampere and seconds are both fundamental units (and coulomb is derived), a coulomb has the dimensions [current][time] i.e. As

What is pottasium permanganate used for in real life?

In medicine, it used to be used for foot fungus, but has long since been superseded by better procedures. It is also the agent used in older home water treatment systems for removal of iron from the water. I'm sure it probably has other uses, too.

What are the problems that an engineer could have while building a new railway line?

obstacles, like towns, roads, and mountains. how do you get past them? what is the least disruptive way to the people and environment?

What causes the popping or tinkling sounds as hot metal pipes cool off?

The sound actually emanates from breaking atomic bonds, and the subsequent rearrangement of the crystalline matrix within grains. This change occurs so quickly, that the material produces a pressure wave (sound wave) that you can hear as a popping sound.

Pretty cool, huh!?

What are the advantages of submarine simulations?

Submarine simulators have been around for decades. Though primarily used in Submarine School in Groton, CT, to train new submariners, they're also used for submarine veterans in pre-deployment training exercises.

The 2 most common are the dive simulator and everyone's favorite, the wet trainer. The dive simulator simulates a submarine control room, with helm, planes, and ballast control panel stations. The trainer is used to give candidates a hands on experience of dealing with emergencies, without the side-effect of dying. Since the Helm/Planesman stations are the first that most crew qualify on, it's the logical choice for a trainer.

Submarine control room trainers for officers are more complex, as they're taught advanced submarine command, control, and tracking/attack procedures.

The wet trainer is exactly what it implies; it is a simulated room of the engineering spaces of a submarine where pressurized water pipes and manifolds with leaks are activated, and the participants work the simulated emergency. The trainer is designed to prepare crews to deal with pressurized water leaks, rising water, and pipe-patching/flood control procedures. In submarine school, it's also a psychological evaluation to see how potential candidates fare in an emergency situation in a closed environment where water is rising.

For pre-deployment training, simulators can help train crews for specific mission tasks, or refresh/hone target acquisition and tracking skills between the key personnel involved during battlestations.

What is the interrupt number in 8085 microprocessor and how to find interrupt's vector address?

The 8085 has five interrupts, INTR, RST5.5, RST6.5, RST7.5, and TRAP. It also has eight software interrupts, RST0, RST1, ..., RST7.

The INTR interrupt requires a hardware response that is an opcode. Usually, the opcode is either a CALL instruction, in which case the interrupt vector can go anywhere in memory, or it is an RST instruction, in which case the vector is based on a table in low memory.

In the case of RST instructions, either directly or via INTR, or the RSTx.5 interrupts, you simply multiply the interrupt number by 8 to get the vector address. The following table presents the vector addresses for all possible interrupts...

RST 0 - 00H

RST 1 - 08H

RST 2 - 10H

RST 3 - 18H

RST 4 - 20H

TRAP - 24H

RST 5 - 28H

RST5.5 - 2CH

RST 6 - 30H

RST 6.5 - 34H

RST 7 - 38H

RST 7.5 - 3CH

How much coolant is needed in an average nuclear power station?

Depends on the amount of fuel remaining. Usually at 78% and at 780 Degrees, A Reactor requires 480 Kilo Litres of Coolant [Water] per Day.

How the power is increases in gas turbine by adding fuel?

Very simply, more fuel burned, more power output. This applies to any combustion engine.

What is the importance of integral calculus in the field of engineering?

Most complex engineering problems cannot be solved without calculus. Force related problems are a great example - how else would you calculate the force exerted on a particle a specific distance from an electrically charged wire?

How generic engineering can improve food supplies?

Genetic engineering can help farmers be more productive by making plants that withstand herbicides and pesticides, have shorter growing seasons, and are more hearty. However, studies have not been fully conclusive on the dangers of genetically altered food supplies.
