A perfect vaccuum is one in which there are no molecules of anything in it. That means no atmosphere, no nothing. But, that has nothing to do with the effects of gravity. Outer space is very close to being a perfect vaccuum but still experiences gravitational fields; if it didn't the Earth would be flung out in nothingness.
No, carbon dioxide (CO2) cannot create a vacuum by itself. A vacuum is defined as a space devoid of matter, including gases like CO2. However, CO2 can be removed from a sealed environment to create a vacuum, but it requires the use of a pump or similar device to evacuate the gas.
It is not possible for a human to swing sword fast enough to create a vacuum. This was a popular theme in many of the Samurai anime. The vacuum create by superhuman speed often lead to devastating attacks in these shows.
You can approximate weightlessness in a swimming pool. NASA astronauts practice maneuvers under water.
You can experience weightlessness by taking a parabolic flight, where the plane rapidly ascends and descends to create short periods of simulated zero gravity. Another option is to visit an astronaut training center where they offer zero-gravity simulators. Lastly, space tourism companies like SpaceX and Blue Origin are developing commercial trips to space where passengers can experience weightlessness.
Normally you create vacuum by pumping out the air from a sealed container. Electric and magnetic fields would seldom be used, unless you had some electrically charged particles that you wanted to remove from your partial vacuum.
No, compressors are designed to increase pressure by reducing volume, not create a vacuum by removing air. To create a vacuum, a dedicated vacuum pump is required which operates by removing air from a closed system.
Astronauts in orbit experience weightlessness because they are in a state of continuous free fall towards the Earth. This creates the sensation of floating in space, as there is no force pushing against them to create the feeling of weight.
Weightlessness is the effect that astronauts enjoy in space.
Only in a vacuum or in space can an object be in a state of free fall without any other forces acting on it, leading to weightlessness. This is due to the absence of air resistance and gravitational forces cancelling each other out.
a vacuum cleaner uses air to create suction. in a vacuum there is no air. Therefore, the aswer is NO.
Weightlessness
you are so weightlessness
Weightlessness is the effect that astronauts enjoy in space.
The root word of weightlessness is "weight."
This is known as free fall or microgravity. In this state, astronauts and objects inside the shuttle experience a sensation of weightlessness because they are falling at the same rate as the shuttle around the Earth, creating the illusion of being in a state of weightlessness.
True weightlessness refers to the sensation experienced by objects or individuals when they are freely falling in a vacuum environment, without any external forces acting on them. This occurs when the force of gravity is canceled out by the acceleration of the object. Astronauts in space experience this sensation due to their spacecraft orbiting the Earth.
In space, there is no gravity and one would experience weightlessness.
