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 machine howeve

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.

hello all, today I posted a new project. That is our VOVE. vove nothing but voice vehicle.this can be operated by the voice. before that you must have to install an application on the mobile phone is Arduino Bluetooth in the android or ios play store. after that connect the mobile Bluetooth to our vove Bluetooth and start the commanding to the vove by tapping the mice in the mobile application. then you will get the result that you coded in the Arduino. if you are interested to study about our vove project visit it in the search box on top by typing vove. ok, guys see you soon with something new👍👍🤔😲😲 until then goodbye. this is sample video have look,               

ALKANES: these are also called paraffin. alkanes are saturated hydrocarbons. the formula of alkanes (CnH2n+2). when the H atom is removed from the alkane then it is replaced by the name of alkyl. the formula for alkyl is (Cn H2n+1). the carbon atom in it shows the sp3 hybridization. the bond length is equal to 1.54°A. ALKENES: these are also called as olefins means form oil products. it possess a double bond between them. the formula is (CnH2n). the carbon atom in it shows the sp2 hybridization. the bond length is equal to 1.34°A. ALKYNES: these are also called as acetylenes. the formula for this is (Cn H2n-2). the carbon atom in it possesses a triple bond and also shows the linear shape means it is in an sp hybridization. the bond length is equal to 1.20°A.

HYBRIDISATION: it is a phenomenon, mixing up of two or more atomic orbitals of different energies and form an identical hybrid orbital. SP3 HYBRIDISATION: the shape of this molecule is tetrahydral shape. the bond angle is 109.28' this is formed by the combination of one S and 3P orbitals. four SP3 hybrid orbitals are formed. SP2 HYBRIDISATION: the shape of the molecule is planer triangular. the bond angle is 120°. this is formed by the combination of one S and 2P orbitals. three SP2 hybrid orbitals are formed. SP HYBRIDISATION: the shape of the molecule is linear. the bond angle is 180°. this is formed by the combination of S and P orbitals. two SP hybrid orbitals are formed.

the human eye is the sense organ in the body to see and identify the objects. the cornea is a layer of the eye that protects eye from the dust and it acts as a protective membrane. behind the cornea, a humorous liquid is filled in a space. the iris contains a pupil in it, iris allows the light to pupil.iris is a muscular diaphragm. the pupil is a hole.it catches the light and does not reflect back.it is in black color. the lens is the backward covered portion to form the image from the retina. NOTE 1: the distance between the lens and retina is about 2.5 cm. due to the deficiency of vitamin A in our body, these symptoms may cause to eye:  night blindness, cornea failure. the retina contains the 125 million receptors called rods and cones which receives the light signal data from the eye and sends it to the brain through 1 million optic nerves.   NOTE 2: the lenses are; concave,convex,bi concave,bi convex,plano concave,plano convex, concavo-convex. HUMAN EYE SIGHTS: there are many comm
