Photons with the highest energy have the longest period?

No, the energy of a photon is directly related to its frequency, not its period. Photons with the highest energy have the shortest wavelength and the highest frequency. Period is the time taken to complete one full cycle of a wave, and it is inversely related to frequency.

Where is the skeleton key in oblivian?

You receive the Skeleton Key as a reward for completing Nocturnal's Daedric Quest, which can be started at her shrine north-east of Leyawiin. Just follow the path on the eastern shore north and you can't miss it.

Note that you must be level 10 to start this quest.

How deep does a depth charge have to go to detonate?

Depth charges are typically set to detonate at a specific depth, depending on the target being pursued. Depths can vary, but they are often set between 50 to 150 meters below the water's surface. This depth is chosen to optimize the effectiveness of the explosion against submarines or underwater targets.

How does car polish work?

All polishing techniques use the same method in principle: polishing is the methodical application of a very fine abbrasive. The paste usually used for car polish is a chalk or limestone emulsion, where the mineral is very finely ground. Modern polish may also use non-mineral abbrasives.

Describe how the reflection of light waves enables you to see your image in a mirror?

When light waves hit a mirror, they bounce off at the same angle they hit the mirror's surface. This process, known as reflection, allows the light waves to maintain their original image as they bounce off the mirror and into your eyes. Your brain interprets the light waves that reach your eyes as an image, enabling you to see your reflection in the mirror.

What is wind fuel?

The wind fuel is one of the forms of renewable energy, in the process of creating wind fuel a generator connected to a propeller and which inturn is connected to a generator which generats power when the wind starts blowing. The power is then stored or relayed to a power plant where in it is stored and used in place of the regular power. Some other forms of renewable energy are Hydropower, Solar power.

What is a fart bomb?

Whomever did the last answer is a complete dunce. A fart bomb is a bag with reacting chemicals inside of it that expand when mixed. The air is filled with a putrid smell when the bag bursts.

What is the effect of the temperature on the gas flow rate?

An increase in temperature typically leads to an increase in gas flow rate due to the gas particles gaining more energy and moving faster. Conversely, a decrease in temperature tends to decrease the gas flow rate as the particles slow down. This relationship is described by the ideal gas law, where volume and pressure are held constant.

How does stealth technology work?

The goal of stealth technology is to make an airplane invisible to radar. There are two different ways to create invisibility:

  • The airplane can be shaped so that any radar signals it reflects are reflected away from the radar equipment.
  • The airplane can be covered in materials that absorb radar signals.

Can falling object increase in speed and decrease in acceleration?

Falling object acceleration is due to gravity, and is therefore a constant.

However, because there is a magnitude to this acceleration, the falling object will continue to increase in speed until it reaches its terminal velocity.

We can also observe this quantitatively.

Imagine that we have an object falling from a cliff.

At initial, the velocity is 0, acceleration is -10 m/s^2(rounded for simplicity).

After one second, we can calculate the velocity.

V= V(o) + a(t)

V = 0 +(-10)(1)

-10 m/s. The speed is just the magnitude of the velocity, or + 10 m/s.

To prove that it will increase even more in speed (even though it already from from 0 m/s speed to 10 m/s speed with negative acceleration), here's another example to further the point which expands on the problem already given.

Let's evaluate speed at 2 seconds.

V= V(o) + a(t)

V= 0 + (-10)(2)

V= -20 m/s. so speed = +20 m/s

Hopefully you can see now that while velocity is decreasing, the magnitude of it, speed, is increasing, and that a falling object always has negative acceleration of about -10m/s^2.

500 degrees equal to how many millivolts?

I am assuming from the question that you want to know about the output from a temperature sensor. While there are some standard types of sensors, the only way to know for certain is to check the specifications for the particular sensor in use. In addition to the specification sheet, the particular sensor will have a calibration factor - the amount it deviates from the standard. That can only be determined by comparing it to a calibrated test source (traceable to known a standard).

What are 3 things you can use as wheels on a mousetrap car?

Alot of people think that the Romans conquered Italy, but actually, corn expires after three weeks of being refrigerated, leading to the death of Archduke of Austria-Hungary, Franz Ferdinand; while this is important, CDs are great materials for wheels.

What is the difference between physical and logical clock in synchronisation?

For many appls:

‰ it is sufficient that all machines agree on the same time.

‰ it is not essential that this time also agree with the real time

E.g. make example - it is adequate that all machines agree that it is 10:00

even if it is really 10:02.

Meaning: it is the internal consistency of the clocks that matters, not

whether they are particularly close to the real time.

For these algorithms it is conventional to speak of the clocks as

logical clocks.

„ Counter-ex:

when the additional constraint is present that the clocks

„ must not only be the same,

„ but also must not deviate from the real time by more than a certain amount,

the clocks are called physical clocks.

How do you re-magnetise a horse shoe magnet?

One way to re-magnetize a horseshoe magnet is to stroke it along one direction with a strong magnet multiple times. This process can help realign the magnetic domains in the magnet and restore its magnetism. Alternatively, you can also subject the magnet to a strong magnetic field using specialized equipment.

Air leaving the evaporator should be around?

there are many answers to this question, and depending on circumstances different answers are correct. but for a home air conditioner a fair rule of thumb is that the leaving air should be 20 degrees cooler than the entering air

How can you make a room sound proof?

There are 4 elements to sound isolation:

- Decoupling

- Mass

- Absorption

- Damping

In a high isolation environment, you would want to deploy all 4 elements.

After that you would look for where the "holes" are in the system.

- Look at ceiling can lights, wall outlets, etc.

- Look at ventilation, ducts, etc.

- The doors and windows

All of these are considered "flanking paths"

What Are Differant types of motion?

* There are a lot of motion kinds. You can have a rotary motion, a circular one like planets' orbit, a Brownian one which is the particles' movement, vibration, linear one or a harmonic one such as functions sin and cos.

Which type of light bulb glows when a filament inside it gets hot?

Incandescent light bulbs produce light when a filament made of tungsten wire is heated by an electric current flowing through it. The filament glows and emits light as it reaches high temperatures.

Can light speed be achieved with gear ratios?

No, Scientists have been able to get microparticles up to speeds close to lightspeed. With today's technology, lightspeed is pretty much our speed limit. Currently if we cant get microparticles up to licht speeds I assume that Gear ratio light speed is a long way off.

How do you make coconut shell charcoal in huge quantity?

To make coconut shell charcoal in huge quantities, the shells are first collected and dried to reduce moisture content. They are then carbonized in large kilns or furnaces at high temperatures in a controlled environment to produce charcoal. This process requires careful monitoring of temperature and air flow to ensure consistent quality and yield.

What is technological use of static electricity?

Paint spraying cars: the paint particles are given a negative charge, and the car frame is given a positive charge, so the paint sprays out, and sicks to the car, and is attracted to all the hard- to reach areas

Electrosatic precipitator; in coal fired power station theses are used to stop the dust particles reaching the atmosphere. Particles of ass pass through a charged grid, and becone charged. They then stick to plated either side of this grid, where they can be disposed of safely

Photocopier; A charged drum is in the photocopier. Light is then shone through the paper, and whete ther is no print light hits the drum and it looses its charge. This leaves charge where there needs to be ink. Ink is the pulled onto the charged drum, and transfered onto paper

Antistatic floors; to avoid static charges in hospital, the floors are made out of an antistatic material, so no charge can build up.

Describe a negative feedback system?

Q: describe the negative- feedback system

subject: Science

A: To control the amount of hormones that are in your body, the endocrine system sends chemical messages back and forth within itself. This is called a negative- feedback system.

example:

it works much the way a thermostat works. when the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. once the furnace has raised the temperature in the room to continue to stay off until the thermostat signals that the temperature system controls the level of glucose in your bloodstream.

What is the next multipole after the octupole?

The next multipole after the octupole is the dodecapole, also known as the 12-pole moment. It contains more information about the distribution of charge or mass in a system compared to lower-order multipoles.

How is the internal energy of a body related to the body's temperature?

Your body temp is around 30 degrees celcius. Your internal energy of a body is the total amount of energy you preserve. Its kind of like total potential energy, and everytime you move your muscles or do anything you are using that internal energy...which is why u need to eat 3 times a day to fuel ur body.. Hope that helps...i didnt want to get into the biology of it.
