THE BLACK HOLE

 

A region is an object with such powerful gravity that nothing can shake it, including light.

The black hole's mass is concentrated during a point of just about infinite density.

this is nothing but singularity. At the singularity, gravity is almost infinitely strong.
it crushes normal space-time out of existence. As the distance from the singularity increases, its gravitational influence reduce.

At a particular distance, which depends on the singularity's mass, the speed needed to flee from the region equals the speed of sunshine.

This distance marks the black hole 'horizon', which is like its surface.

Anything that passes through the surface is trapped inside the black hole. Black holes are available several varieties, counting on mass.

black holes are formed due to the collapse of large stars at the end of their life cycle.

Does OUR SUN BECOME A BLACK HOLE?

no, why means read the following data carefully.


Our Sun is really too small to finish up as a region. our sun does not contain enough matter to exert that
kind of gravitational force on itself. if the sun becomes a black hole, it has to be more than 10 times greater mass.

NEWTON LAWS

ONE NEWTON = ONE KG METER PER SECOND SQUARE.  NEWTON FIRST LAW : states that inertia of motion. any object can't be move unless there is a force exerts on it. NEWTON SECOND LAW: states that force is equal to the product of mass into acceleration(momentum). NEWTON THIRD LAW: states that when two objects interact together then they apply forces to each other equal size and opposite direction. which means for every action there is an equal and opposite reaction.

GSM GLOBAL SERVICE FOR MOBILE COMMUNICATION

GSM IS NOTHING BUT GLOBAL SYSTEM FOR MOBILE COMMUNICATION. GSM SIM 800A: HIGHLY MODERN GSM.MOST POPULAR AND ADVANCED GSM CONNECTION BETWEEN GSM AND ARDUINO: WHENEVER WE WANT TO CONNECT THE GSM TO ARDUINO IS QUITE SIMPLE WHY BECAUSE WE HAVE TO MADE ONLY THREE CONNECTIONS. THEY ARE:[TX AND RX AND GROUND] GSM IS AN INTERNATION STANDARD; THERE ARE SEVERAL GSM MODULUS SIM900,SIM 800A,SIM 808,GSM 520 etc, also, there are several subcategories in the above modules. NOTE: the sim 800A can send or receive data over GPRS, send or receive SMS, and voice calls. it can communicate with pc or microcontroller. AT commands are the main communication commands to all gsm modules. AT means attention commands. specifications of gsm 800a: it operates on quad-band 850/1900 MHz. weight around 40grams. current must be more than 1 ampere. supply voltage range 5v-20v. it can hold the sim card. two LEDs are used in it, one is for network led and the other is for ring led. the above-mentioned specifications are s...
