Does air defy gravity?

Answers

Answer:

If you were to inject air into space what would have happen?

Explanation:

In order for air to defy gravity, it would require atmospheric pressure. But air dosen't defy gravity unless it has the support of atmospheric pressure.

can gas pressure sometimes be greater than atmospheric pressure?​

Answers

Answer:

PRESSURE is a force exerted by the substance per unit area on another substance. The pressure of a gas is the force that the gas exerts on the walls of its container. ... Atmospheric pressure varies with height just as water pressure varies with depth.

Explanation:

Options A and C are the noble gases because their outer shell is complete and they do not react with anyone.

What are noble gases?

All seven of the chemical elements that make up Group 18 of the periodic table are considered noble gases. Helium, neon, argon, krypton, xenon, radon, and oganesson are the constituent components (Og). Noble gases are inert, tasteless, odorless, and nonflammable gases. Since it was initially thought that these elements could not link to other atoms, that is, that their atoms could not combine with those of other elements to create chemical compounds, they were typically given the Group 0 designation in the periodic table.

The more suitable name, Group 18, has been given to them as a result of their electrical structures and the discovery that some of them do in fact form compounds.

A diver jumps off of the platform and accelerates towards the water at 9.8 m/s2. The diver has a mass of 54 kg. At what force, will the diver jump into the water?

Answers

Answer:

The answer is 529.2 N

Explanation:

The Formula for Force is F=M*A

Force equals mass times acceleration,

The mass is 54kg and you multiply that by the acceleration which is 9.8m/s^2

54*9.8= 529.2N

All you have to do is multiply the two numbers when it comes to finding the force.

In a Compton scattering experiment, scattered photon is found to have its wavelength three times of the incident photon for the scattering angle of 180°. Calculate Wavelengths (in nm) of the incident, scattered photon, and Compton shift.​

Answers

Answer:

Two of Einstein’s influential ideas introduced in 1905 were the theory of special relativity and the concept of a light quantum, which we now call a photon. Beyond 1905, Einstein went further to suggest that freely propagating electromagnetic waves consisted of photons that are particles of light in the same sense that electrons or other massive particles are particles of matter. A beam of monochromatic light of wavelength \lambda (or equivalently, of frequency f) can be seen either as a classical wave or as a collection of photons that travel in a vacuum with one speed, c (the speed of light), and all carrying the same energy, {E}_{f}=hf. This idea proved useful for explaining the interactions of light with particles of matter.

When the rudder moves to the left the plane will move to the right or left?

Answers

To turn the aircraft, the pilot uses all three flight controls. The rudder is controlled in the cockpit by foot pedals. When the pilot presses the left pedal, the rudder deflects to the left. This deflection creates more lifting force on the right-hand side of the rudder, which moves the plane's nose to the left.

Answer:

The rudder will move to the right

Explanation:

This is using opposite forces and aircraft speeds to identify the modules used to make the rudder move the plane. If the rudder moves right, the plane goes left. If the rudder goes left, the plane goes right.

CHOICES:
- It has a high amplitude
- It has a low amplitude
- It has a high frequency
- It has a low frequency

Answers

Answer:

It has a high frequency

Explanation:

A wave is the form of sine wave which has crests and troughs. A wave with a long wavelength has a low frequency.

What is the wavelength?

Wavelength is the distance between the adjacent crest or trough.

Wavelength is inversely related to the frequency as

f = v / λ

This shows that longer the wavelength, low will be the frequency.

Thus, a wave with long wavelength infers that is has a low frequency.

please give answer if you know​

Answers

P = Force/Area

= Weight/Area

= Mass × gravitational field strength/Area

= Density × Volume × gravitational field strength/Area

= Density × Area × height × gravitational field strength/Area

P = height × density × gravitational field strength

Hence, P = hdg

The pressure is the force applied on per unit area of an object. It can also be described as the product of height, density, and gravitational field strength.

What is Pressure?

Pressure is the force applied perpendicular to the surface area of an object over which that force is applied. Gauge pressure is the pressure that is relative to the ambient pressure on an object. Various units of power are used to express pressure of an object. The SI unit of pressure is Pascal (Pa).

Pressure of an object can be calculated by the formula:

P = Force/Area

P = Weight/Area

P = Mass × gravitational field strength/Area

P = Density × Volume × gravitational field strength/Area

P = Density × Area × height × gravitational field strength/Area

P = height × density × gravitational field strength

Hence, P = h × d × g

Therefore, the pressure of an object can be calculated as the product of height, density, and gravitational field strength.
