You can. Something can be "hot" in a vacuum. For example: a sealed thermometer in space will read hot if it was facing the sun, but very cold if it was in full shadow (assuming it didn't explode from the absence of pressure holding it together.) So yes, as long as the heat source did not require naturally occurring oxygen for combustion as the moon doesn't have any - or an atmosphere - and heat transfer was carried out via direct contact with a heating device. For example: An electric element would function the same on the moon as it does on Earth - meaning it would radiate heat and be hot to the touch.a microwave oven would also work fine on the Moon. Of course the same liquid fuels that propel a rocket into space would work on the moon - to replace the (Earth based camping "gas" stove) with a liquid oxygen and hydrogen "burner". Of course the electric element would be a tad safer to operate.
Remember that the surface of the moon during "daylight" is approximately 107 degrees centigrade. So given that day temperature, and a radiant heat source, cooking something on the moon is certainly possible. If you were on the dark side of the moon, then the same principle would apply - fueled or radiant heat source, transfer through contact etc. However on the dark side the temperature falls to below 150 degrees centigrade. So you would need a very strong heat source to overcome that degree of cold. Not to mention that whatever you were cooking (for example: an egg) would freeze on the top while being heated on the bottom. Or, assuming heating was taking place top and bottom, it would freeze as soon as it was removed from the heat source. So possible? Absolutely. Even remotely practical? Nah...
A thermocouple produces a tiny voltage proportional to the temperature difference between two junctions where dissimilar metals meet.
Thermocouples use rare-earth metals (chromium, aluminum, nickel, etc), usually in pairs. As these metals heat up, they react with one another and one metal sheds off an electron, which is then seen as electricity. Thermocouples usually produce a very small amount of electricity, often only enough to operate electric 'gates'.
The 'normal' speed of sound is 340 m/s in dry air at room temperature and pressure.
From your question, it appears we should differentiate the terms "ultrasonic" and "supersonic".
Ultrasonic relates to sonic frequencies higher than 20 KHz, i.e. beyond audible range. For a given gas, the speed of sound is independent of the frequency of the sound measured and also independent of the density of the gas.
Supersonic relates to a speed of an object greater than the normal speed of sound (340 m/s in air at STP) and usually the phenomena associated with it.
The speed of sound is also a functionof the medium through which it's passing. For example, the speed of sound through water is 1,500 m/s, and is slightly over 5,000 m/s in iron.
So to answer your question, the speed of ultrasound in airis340 m/s for the reasons given.
The 'arc' in arc welding is not an acronym but in turn is a reference to the electric arc that is being generated during the welding process.
Constellations are used as a way of mapping surrounding space so that's its easier for us to find certain planets/stars alot easier. Also in history these constellations have being used for astrology which is suposerly a way of reading ones future, hope this helps
A gigaquad is a measurement of information in Federation computers. Gigaquad measurements are used for amounts of information exceeding one billion quads. While Federation computers still use binary code in some capacity, they also are known to use trinary code. This is much more advanced than ancient computers which used bits (limited to a "one" or "zero" state) and bytes as small information measurements, so it is impossible to compare the bytes with quads.
There are several exercises that can be done in zero-G, any of which you can do here on Earth.
"Isometric" exercises, in which you use one muscle in opposition to another, require no equipment and can be done anywhere. Here's an example; press your two hands together. Push HARD. Relax. Push; relax. This is an "isometric" exercise, meaning "same movement". Here's another; Place your left hand on the inside of your right knee, and the right hand on your left knee. Use your arms to push your knees apart, and use your legs to pull them together. Or, reach down and grab your chair, and PULL yourself down into the chair. (Please DO NOT do this one in the seat of a fighter jet, as you might accidentally grab the alternate ejection seat handles!)
Other exercises that can be done on Earth or in zero-G involve flexing against a bungee cord or large rubber band, or using a resistance device like a rowing machine or a stationary bike.
The bad news is there are a limited number of jobs, and the qualifications are pretty intense. In addition to a bachelor’s degree, you also must have a master’s degree or two years of PhD work in specific STEM areas. You also qualify if you’re a medical doctor or if you’ve begun or completed a test pilot program. From there, you also need to fit into one of the areas of specialization (two years of biological and medical science, physical science, or engineering and operations work experience, or fit their pilot qualifications).
And of course, you’ll have to be okay with the “extensive travel” required.
The first person to travel in space was Soviet cosmonaut Yuri A. Gagarin (1934-1968). He traveled aboard the Vostok 3KA spacecraft, known as Vostok 1, which was launched April 12, 1961, in a flight lasting one hour and forty-eight minutes.
Yuri Alekseyevich Gagarin, Hero of the Soviet Union, was a Soviet cosmonaut. On 12 April 1961, he became the first person in space and the first to orbit the Earth. He received many medals from different countries for his pioneering tour in space.

Jenaro Gajardo Vera (*November 18, 1919 in Traiguén, Malleco Province - †May 3, 1998 in Santo Domingo, San Antonio Province) was an eccentric lawyer, painter and Chilean poet. He became famous from September 25 of 1953 until his death, as the legitimate owner of the Moon.
The United Nations 1967 publication "Outer Space Treaty" states space is the "province of all mankind", and is not subject to claims on sovereignty by States. As treaties apply to States and place obligations on States, and since the Space Treaties were drafted at a time when, realistically, the only "people" going into space were States, none of the space treaties make reference to private parties. The Outer Space Treaty of 1967 has currently been ratified by 98 states, including all the major space-faring nations.
The international Moon Treaty, finalised in 1979 and entering into force in 1984, forbids private ownership of extraterrestrial real estate. However, as of January 1, 2008 only 13 states have ratified the agreement, and none of these are major space-faring nations. Kazakhstan has ratified the treaty and is host to the Baikonur Cosmodrome. However, the facility is operated through a leasing agreement by Russia.
There are more space technology spinoffs than people realize, and though most are used in Engineering, Industrial, and Scientific applications, but a few consumer applications that are more well known are:
Lithium Ion Batteries - not originally developed for NASA, but NASA funded further development to power the HST / ISS Pistol Grip Tool. The technology has found its way into the global marketplace.
Solid State Devices (SSD) - SSD technology was developed for the Hubble program. The original recording device on Hubble actually had magnetic recording tapes; the Solid State Recorder, developed in the early 90's and deployed on HST on the 1st Servicing/Repair mission, replaced the old recorder and is the foreunner of SSD devices. SSD technology is widely used today in Flash drives, SSD disk drives, etc.
Tempurpedic Foam (Memory Foam) - The Tempurpedic company is the only one that used NASA's technology for memory foam, using the patented NASA technology through NASA's partnership program. The material was specifically designed for use on Astronaut seats in the Shuttle.
Imaging Technology - CMOS sensor technology, widely used in digital cameras, medical scanners, and many other applications, was further developed for use on the Hubble Telescope. Imaging technology continues to advance as a result.
MARCbot - The MARCbot, currently used by thousands of soldiers in Iraq to locate IED's, was significantly upgraded by NASA engineers, improving its capability, mobility, and cost per unit.
You can view many of the hundreds of spinoffs at NASA's Spinoff site - the link is below.
Each of the four wheels ran on an independent electric motor powered by the main batteries onboard the rover.
A total of 12 men have walked on the moon, so far. All were US astronauts in NASA's Apollo moon landing program. Six missions landed on the Moon between 1969 and 1972.
Neil Armstrong (38), Buzz Aldrin (39) - Apollo 11
Pete Conrad (39), Alan Bean (37) - Apollo 12
Alan Shepard (47), Edgar Michell (40) - Apollo 14

People visit space for several reasons:
Until May 2010, there is no baby born in the space, the NASA or another space agency prohibit astronaut from being pregnancy while operate a mission .
Except in the special mission, the reason is in the womb phase , baby will adapt with gravity, after born, infant will learn to walk and adapt with earth gravitation, but the space condition with zero gravity takes all the environment support for human to growth.
but when human growth in the space for a whole of his life, it will be different, the physical result will shape human body to thin leg, but long , tall height, and the human agility is faster than human in the earth.
The problem is fuel. In space, there are no brakes, nothing to slow you down - except the thrust of your own rockets. Fuel is scarce and precious (like everything else in space) and at the end of the trip, there isn't any left. So the only way to slow down is to skim lightly through the upper layers of the atmosphere, and allow friction between the spacecraft and the upper atmosphere to slow you down.
transitors amplify signals in a very non-linear fashion. somehow (i don't know how), adding in the negative output of the transistor (negative feedback loop) makes the output much more linearmostly for stabilization, but there can be other reasons in specific cases.
Liquid fueled rockets get it from liquid oxygen, and solid fueled rockets get it from and oxidized metal.
The spacecrafts come down slowly as three large parachute help it to land , and the U.s.A choose the sea for double safety.
