 Ok guys, these are the inventions and scientific names which changes the world like this:  tuning Fork invented by the conig. The sound was recorded and reproduced for the first time by Edison next. The first law of thermodynamics was introduced by the Joul. Weber scientists introduced the molecular theory of magnetism. And this theory of magnetism improved by the eving. Scientists coulomb invented the law of magnetic forces. Bennett invented the gold-leaf electroscope. Michael Faraday introduced electrolysis. The first theory of Hanson oerested is invented by a wire carrying current behaves like a magnet. E Goldstein proposed the positive rays. JJ Thomson proposed the cathode rays. Proton was discovered by  Rutherford. Neutron was discovered by James Chadwick. Discovery of electrons by millicon. X-rays  invented by rontgen. Artificial radioactivity was discovered by Joliot and iren curie. Artificial transmutation was introduced by Rutherford. Nuclear fission ...

CONTROL OTHER PHONES WITH YOUR MOBILE(SIMPLE TRICK): PROCEDURE TO HACK A MOBILE: install the application into the whom you want to control. here we are providing the two applications in the below.follow the procedure to control. one is for an android version less than 8.1 and another is above for above the 8.1. be careful to use this application. you need to agree and accept all the permissions by studying carefully. then press allow. once you installed the following application into your friend's mobile then you need to open and site called cell tracker. io,  then you need to enter a code that is showing on the application installed mobile. and you need to enter the code on your mobile service called celltracker.io to access the guy mobile. where you can send the commands then you will get according to commands like call history, Facebook data, chat history, taking a live photo, screen recording, screenshots. download the applications from here ; above a...

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...

Hello all,  today I explained the satellites. study carefully. satellite is nothing but an object that revolves around the planet in a curved path. satellites are two types: natural satellites(the moon is a satellite because which revolves around the earth) artificial satellites(human-made) coming to the topic of artificial satellites; artificial satellites are made by the human and launched by the human through the rockets into the orbit of the planet. the satellite launching involves two steps: the satellite has to be taken into the desired altitude. pushed out from the spacecraft at the right velocity to begin and maintain it's orbit. the satellite launch vehicle moves straight only for a few seconds. A satellite launch vehicle is a multistage rocket, consists of a smaller booster rocket for boosting. boosters give the rocket initial thrust during the launch and carry the vehicle rarely part of the flight. when the fuel completed in the boosters they fall away from the rocket ot...

space x is a private company. The founder of this company is Elon Musk. What is the Starship program? The specific Starship gets to Mars and back to the earth. the starship is a spacecraft.  Space x's grandest upcoming rocket was once known as the interplanetary transport system. the big Falcon rocket  but most recently it has settled on the name Starship. space x founder Elon Musk has announced a complex and ambitious plan to put crewed starships on Mars in the coming decades.  The plan involves several flights and re flights of both Starship vehicles and the super-heavy boosters. Ultimately the goal of Elon Musk is to have a system through which hundreds of people at a time can travel to Mars.  Whether to colonize or just to visit, at a relatively low cost. if the system of Elon Musk proposes really does run at optimal speed, like a well-oiled train line, interplanetary travel May become something we begin to see a lot more of an important part of the space fairing...

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.

 HELLO ALL, TODAY I WANT TO EXPLAIN ABOUT THE THERMODYNAMIC LAWS thermodynamic laws are : 1. first law: it states that energy neither be created nor be destroyed, it always changes one form to another form. 2. second law: it states that energy can change the position of any object but the state of energy is potentially reduced comparing to the initial state. 3. third law: it states that the thermal energy per unit temperature of a system approaches a constant value as the temperature absolute zero. zeroth law: if two systems are in thermal equilibrium with the third system then these three are also in thermal equilibrium.

The periodic table is invented due to avoid confusion while searching and locate the elements. at that time chemists are started to frame ways to group these elements and compounds on the basis of their physical and chemical states. at the beginning of the 18 th century, a scientist called joseph Louis stated that the hydrogen atom is a building material and atoms of all other elements are simply due to a combination of a number of hydrogen atoms. and also considering some examples the atomic weight of hydrogen is taken as ONE. DOBEREINER'S TRIAD THEORY: dobereiner's he was a German man. he was tried to prove the relationship between elements of their properties and atomic weights. he stated that the arrange the three elements are in ascending order which has similar properties with the help of atomic weights. and the middle element is the average of the first and third elements. this theory is called the law of triads. limitations: this law failed for low mass and very high ma...

  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. ...
