How do space observatories work?
they have multiple lenses that focuses on a small space object millions of miles away with great precision.
List the planets distances from the sun?
The distance of Mercury from the sun is 57,910,000 kilometers while Venus is 108,200,000 kilometers away. The Earth is 149,600,000 kilometers away from the sun while Mars is 227,940,000 kilometers apart from it. The largest planet, Jupiter is 778,330,000 kilometers distant from the sun while Saturn is 1,424,600,000 kilometers away. The last three planets namely Uranus, Neptune, and Pluto are 2,873,550,000 kilometers, 4,501,000,000 kilometers, and 5,945,900,000 kilometers away from the sun respectively.
How far is the mars in kilometers from the sun?
Mars is 267,000,000 kilometers away from the sun.
How does angle of incidence control the intensity of solar radiation received at the earth's surface?
The angle of incidence is what trajectory the suns burst is taking. If the burst is pointed 20 degrees in any direction, slightly away from the earth, then the intensity of the impact on earth would be less severe since only a portion of the burst is actually making contact. While the rest of it flies into space for millions and millions and millions of kilometers.
How many kilometers away is Sirius B?
I don't know for sure, but it's about 8.7 ligt years away, and a light year is 9.5 trillion kilometers away. if you multiply that, you're bound to get the answer.

oval

What is the defernition for bifocal?
Bifocal is a type of corrective lens. Bifocal lenses are divided into two sections, usually the top for seeing far away objects and the bottom for seeing nearby objects.
Difference between optical zoom and digital zoom?
Optical zoom uses lenses to focus on objects further away... it is the lenses which do the 'zooming'. Digital zoom is where a photo is taken using the same set of lenses all the time and using software to enlarge the picture.
Corrective lenses that have two different refractive powers that are located one on top of the other are known as?
Corrective lenses with two different refractive powers located one on top of the other are known as bifocals. Bifocals allow a person with both myopia (nearsightedness) and hyperopia (farsightedness) to see objects both near and far away (a person with nearsightedness CAN see objects nearby, but has a hard time seeing objects far away).
Do reading glasses magnify objects that are at least two meters away from you?
Reading glasses are typically designed to magnify objects that are within arm's length away, around 16-18 inches. They are not intended to magnify objects that are farther away, like those at least two meters away. For distant objects, regular prescription glasses or contact lenses are more suitable.
Can contact lenses have glue?
NO, if glue gets on contact lenses, fling them away! They WILL damage your eye !
How many kilometers away is the moon?
It's about 384,000 kilometers away, on average.
Is gravity a motion?
The pull of gravity between two objects depends on more than just the objects. Gravity's effect also depends on the distance between the objects. objects that are closer together have a greater attraction between them. The attraction is weaker when they are farther apart. Gravity exists wherever there is mass, such as in stars and planets.The gravity of each of these objects affects other objects in space.Earth's gravity, for example, reaches millions and millions of kilometers into space.It grows weaker the farther away from Earth you get. Recall that because the moon is less massive than Earth, an astronaut standing on the moon weighs only one-sixth as much as on Earth.The astronaut's weight would change between Earth and the moon.The effect of Earth's gravity becomes less as the distance from Earth increases.
How many miles away is the Nile river from the pyramids of Giza?
about 100km away
Are stars far away?
Yes. Very, very, very far away. The Sun is about 90 million miles away. Other stars are millions of millions of miles away.
What kind of lens helps you to see far away?
convex lenses
