Why do dust particles in a bean of sunlight appear to sparkle?
Because the sunlight is reflecting off them at different points.
What holds the sand particles on the moon as there is very less gravity?
The particles on the moon are densely packed and only small amounts of the particles fly up and away as dust.
Why do the tails of comets always face the sun?
Or "face away," maybe? A comet's tail always points away from the Sun, because it is blown that direction by ions streaming out from the Sun (solar winds). So, whenever a comet is moving away from the Sun, its tail will stream ahead of it.
Raindrops are formed when water vapor condenses on?
particles of dust and other particles in the atmosphere.
Does comet tail possible to can seen pointing towards earth?
A comet's tail points away from the sun. Sometimes the dust and gas separate, though, because they are driven by two different effects, radiation pressure and solar wind, respectively. Both point mostly away from the sun, but not always exactly. Photographs of Comet Hale-Bopp show this effect well, for example, the Astronomy Picture of the Day at the link shown. A comet in deepest cold space is generally thought of as a giant dirty snowball with the snow made of water ice, and frozen organic liquids, and the dirt of small rocks and dust which are the debris of explosions and collisions of different bodies in space. It is only when the comet approaches the sun and warms up that surface ice melts and vapourises carrying dust with it and forming a large cloud that we can see clearly. It is at this stage when the effects mentioned above act on the cloud and sweep it behind the comet relative to the sun to form a tail or tails, and because there is no atmospheric air in space the tail always points away from the sun even when the comet is travelling away from it.
Why do comets tail always stream away from the sun?
Comet tails always stream away from the sun due to the solar wind, which is a stream of charged particles emitted by the sun. The solar wind pushes against the gas and dust particles in the comet's coma (a cloud of gas and dust surrounding the nucleus) and causes them to form a tail that points away from the sun.
How does the behavior of a comets dust tail from a comet ion tail?
An ion tail is made of electrically charged particles and a dust tail is made of dust. Also, an ion tail will always point away from the sun because of the solar winds, while a dust tail tends to follow the comet's orbit and doesn't always point away from the sun.
What happens in plants after rain?
Before rain occurs there are a lot of dust particles present on the stomata's of the leaf of the plant. As there are dust particles on it they look dull and dark. After rain occurs the dust particles are washed away. The dullness is gone when it is washed away. If rain doesn't occur the the plant may die due to suffocation.
Why do dust particles in a bean of sunlight appear to sparkle?
Because the sunlight is reflecting off them at different points.
Is the tail of Halley's comet is always opposite to the sun?
A comet's ion (gas) tail always points directly away from the sun. Some comets also have a dust tail (antitail) which may curve slightly away to the side of the ion tail.
Dust particles exist in what phase?
Dust particles are solids.
What phase do dust particles exist?
Dust particles are tiny particles of solid material.
What holds the sand particles on the moon as there is very less gravity?
The particles on the moon are densely packed and only small amounts of the particles fly up and away as dust.
How is the tail of a comet created?
The Comet's Tail forms when sunlight causes the Comet's ice to change to a gas. The gas or ion , tail of a comet streams from the comet's head, carrying with it dust particles. The solar wind electrically charged particles, expand away from the sun pushes the gas away from the comet's head. Regardless of where its going the tail points away from the sun.
Why are there two tails to some comets?
A comet generally has two tails, not one. One tail is due to the comet's dust particles, the other is due to ionized gas from the comet coma. Dust particles form the first tail. The only force that affects these small particles in space is the radiation from the Sun. This radiation pushes the tiny dust particles in the direction from which they came. Thus, this comet tail generally points back along the comet trajectory. Ions which first come from the nucleus as neutral gaseous particles, are swept into the second comet tail by interaction with the Sun's magnetic field. This field sweeps past the comet nucleus and carries the ions with it to form the tail. Because of the special interaction with the magnetic field, this tail always points directly away from the Sun.(check the related link for an image)
Why does the pharynx need to have the cilia?
The cilia is supposed to keep the dust particles away from the alveoli. The dust from the air that is inhaled from the mouth is filtered by the cilia in the pharynx.
What kind of tail of a comet always points away from the sun?
The dust tail and the gas tail BOTH point away from the Sun (or in the direction of the Solar Wind). As the gas tail is a little less dense, its point is a little more directly away.
