The Hubble Telescope The Hubble Telescope is a large telescope that orbits Earth. It was named after Edwin Hubble. Hubble was an

astronomer. The Hubble was launched in 1990 by NASA, the United States' space program. It uses a 94- inch mirror to collect light. Data are sent back to Earth by radio. Since it is above Earth's atmosphere, it gives us clearer pictures of space than telescopes on Earth can. It can also see farther. With this powerful tool, we've learned a lot about the universe. What Scientists Have Learned from the Hubble The Hubble has allowed us to watch stars form. It also has let us see into distant galaxies. We've been able to test our ideas. For example, before the Hubble, black holes were just a theory. We didn't know for sure that they existed. The Hubble has shown us evidence of black holes in space. The telescope has helped us find places to land data-gathering robots on Mars. We've used it to track the paths of comets. We've also been able to see volcanoes erupt on 10, one of Jupiter's moons. Telescopes that are larger than the Hubble are now being created But the Hubble is the first of its kind.
Why does being in outer space make Hubble a better telescope?

The cosmic microwave background essentially looks the same in all directions. This is an example of.
pentagon [3]

In general, all views of the cosmic microwave background are identical. Isotropy is demonstrated by this.

<h3>What exactly is isotropy, for instance?</h3>

The Greek words isos (equal) and tropos, from which the term "isotropy" is derived, mean "uniform in all directions" (way). The material properties of anisotropic materials, such as graphite, differ depending on the direction, in contrast to isotropic materials like glass, which show the same properties in all directions.

There is no "centre" to an isotropic universe, which is another characteristic. The North and South Poles are produced by the rotation of the Earth, giving them a distinctive orientation, but the Universe is visible from every angle. When we think about the Big Bang, which is the origin of the Universe, this is a crucial point.

Two identical positive charges are placed near each other. At the point halfway between the two chargesTwo identical positive ch
Nitella [24]

Answer:The electric field is zero and the potential is positive.

Explanation:

Two identical positive charges are separated by a certain distance and midway between charges two identical positive charges are placed near each other.

So the Electric field at midway is zero because the electric field due to both charges add up to give zero electric field.(because they point in opposite direction)

Potential is scalar quantity and charges are positive so they add up to give potential.

Which of the following is not a reason fluorescent lamps are advantageous over incandescent lamps?
Wewaii [24]
The correct option is A.
Fluorescent lamps have many advantages over incandescent lamps and the options given in B, C and D are part of these advantages. The option given in A is a disadvantage and not an advantage. This is because, as a result of operating at an higher temperature, it will gives out and radiate more heat.
