570. What is Kuipter Belt?

The Kuiper Belt is a collection of bodies outside the orbit of Neptune that, if nothing else had happened, if Neptune hadn’t formed or if things had gone a little bit better, maybe they could have gotten together themselves and formed the next planet out beyond Neptune. But instead, in the history of the solar system, when Neptune formed it led to these objects not being able to get together, so it’s just this belt of material out beyond Neptune.
 
569. What's the difference between hacking and cracking?

The difference is that a hacker is someone that uses their extensive knowledge of computer logic and code for malicious purposes, while a cracker - looks for back doors in programs, and exploits those back doors. Cracking is generally less harmful than hacking. Hackers are usually involved with web related hacking, like MySQL interception, or phishing, other forms of hacking would include things like brute force, or password lifting.
 
568. What is Pixel?

The pixel (a word invented from "picture element") is the basic unit of programmable color on a computer display or in a computer image. Think of it as a logical - rather than a physical - unit. The physical size of a pixel depends on how you've set the resolution for the display screen. If you've set the display to its maximum resolution, the physical size of a pixel will equal the physical size of the dot pitch (let's just call it the dot size) of the display. If, however, you've set the resolution to something less than the maximum resolution, a pixel will be larger than the physical size of the screen's dot (that is, a pixel will use more than one dot).
The specific color that a pixel describes is some blend of three components of the color spectrum - RGB. Up to three bytes of data are allocated for specifying a pixel's color, one byte for each major color component. A true color or 24-bit color system uses all three bytes. However, many color display systems use only one byte (limiting the display to 256 different colors).
 
567. What is Pellet Gun?

A pellet is a non-spherical projectile designed to be fired from an air gun. Air gun pellets differ from bullets and shot used in firearms because of the pressures encountered: airguns operate at pressures as low as 50 atmospheres, while firearms operate at thousands of atmospheres.
Wood pellets are the most common type of pellet fuel and are generally made from compacted sawdust and related industrial wastes from the milling of lumber, manufacture of wood products and furniture, and construction.
 
566. What is deepest point on earth?

The Kola Super deep Borehole Russia ,is the result of a scientific drilling project of the Soviet Union in the Pechengsky District, on the Kola Peninsula. The project attempted to drill as deep as possible into the Earth's crust. Drilling began on 24 May 1970. Boreholes were drilled by branching from a central hole. The deepest, SG-3, reached 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth. The borehole is 9 inches (23 cm) in diameter.
 
2. What is the electrical conductivity of acids and bases?

Acid and Bases have different different electrical conductivity based on density of free ions present in it. A strong acid/base conduct electricity easily. More strong means more the number of ions. Let us suppose, if you are connecting a bulb in a circuit with strong acid/base solution, bulb will glow accordingly.. if you are connecting it with weak acid/base solution, bulb will not glow significantly.

It just depends on strength of acid/base.Both can conduct electricity.
 
3. How hot does it get on Mars?

The temperature on Mars may reach a high of about 70 degrees Fahrenheit (20 degrees Celsius) at noon, at the equator in the summer, or a low of about -225 degrees Fahrenheit (-153 degrees Celsius) at the poles.
 
4. How many Sudoku puzzles are there?

There are a total of 6,670,903,752,021,072,936,960 possible solutions, yet when mathematicians took away rotations, reflections, permutations and relabeling, which takes away the same puzzle in just a different form, the number of solutions was 5,472,730,538.
