About the Electron

A little about electron 

 1- It Discovered in cathode ray experiment

2- charge = -1.602 × 10-¹9 coulomb (discover by Mulliken in his oil drop experiment)

3- Mass of electrons = 9.11×10-³¹ kg (by J.J. Thomson)

4- Specific charge of electron (e/m ratio) = 1.76× 10 8 coulomb's/gm .
(It decrease with increase in velocity because the increase in velocity increase the mass of electron)

5- Dencity of electron = 2.17 × 10¹7 gm/cc

6- Radius of electron = 10-¹5 cm

7-Mass of one mole of electrons (N electron)
= 0.55 MGM (nearly)

8- charge on one mole of electron =96500 coulomb's = Faraday (nearly)

Siemens Ozoniser how Siemens Ozoniser work

Siemens Ozoniser:  This Ozoniser consist of two co-axial glass tubes fused together at one end. The outer side of the outer glass tube and the inner side of the inner glass tube are finally coated with tin foils as shown in the figure given below.  (Siemens Ozoniser)->2                                                     (Siemens Ozoniser)->1 These tin foil are connected  to the induction coil for supply of silent electric discharge. Pure and dry oxygen gas is passed into the apparatus through annular space. The gas is then subjected to the action of silent electric discharge where oxygen gets converted into ozone. The ozonised oxygen then comes out  of the apparatus through the outlet of the Ozoniser. (Siemens Ozoniser)->2

Hyperloop

  Hyperloop is a proposed mode of transportation that involves high-speed travel in a low-pressure tube. The concept was first introduced by entrepreneur Elon Musk in 2013, who suggested that it could offer a faster, more energy-efficient alternative to traditional high-speed trains, airplanes, and other forms of transportation. The Hyperloop system would involve using magnetic levitation to propel pods through a tube at speeds of up to 760 miles per hour (1,200 kilometers per hour). The tube would be mounted on pylons, elevated above the ground to avoid interference with other forms of transportation, and equipped with a low-pressure environment to minimize air resistance. One of the proposed advantages of the Hyperloop is its potential to significantly reduce travel time. For example, a trip from San Francisco to Los Angeles, which normally takes about six hours by car or one hour by plane, could take as little as 30 minutes using the Hyperloop. Additionally, the system could be ...

Introduction to DOS

Introduction to DOS ➡️ DOS stands for (Disk operating system), and it is a name for the basic IBM PC operating system. DOS is command User/Line interface (CUI) Operating system software. Several varieties of DOS are available , including Microsoft's versions of DOS (MS-DOS) , IBM's version (PC-DOS) , and several others.             There are actually several levels to DOS. At  the lowest level is the BIOS  (Basic input/output system)  which is responsible for managing devices like the keyboard and disk drivers at simplest possible lavel e.g. the BIOS let's you say things like ( get me sector 5 of track 3 from disk drive 1). This is done partly by software in ROM (Read-only memory) and partly by BIOS extension, which are loaded when the system first starts up (with MS-DOS, these are in a file called IO.SYS; on PC-DOS they're in IBMBIO.COM).     The second layer provides a set of higher level services implemented using the low-level B...
