# Speed= Distance/ Time  # Time = Distance/ Speed  # Km/hr to m/s conversion:    X Km/hr = (x × 5/18) m/s  # m/s to km/hr conversion:     X m/s = (x × 18/5) km/hr  # If the ratio of the speeds of A and B is a : b, then the ratio of the time taken by them to cover the same distance is 1/a : 1/b or b : a  # Suppose a man covers a certain distance at x km/hr and an equal distance at y km/hr. Then,the average speed during the whole journey is   (2xy/x+y) km/hr Thank you  Regards SSA Sai Group

 The atomic orbitals of same energy or nearly same energy intermix to give new orbitals of same energy # Half filled orbitals.       Empty orbitals.           Full filled orbitals.  All can do hybridization # The number of hybrid orbitals = Number of intermixing orbitals # The concept of hybridization is for Sigma(single bond) bond and lone pair. # Hybrid orbitals are named after the parent orbital  1s + 1p = sp, sp  1s + 2p = sp2, sp2

 Q1) What is a pixel? Ans- Pixel is a small dots or squares that make up a image or a screen Many pixels make a screen, every screen has many pixels. Q2) What is HLA typing Ans- HLA typing is a kind of genetic test used to identify certain individual variations in a person's immune system.  This is especially used to find out the type of blood, it is important to know HLA typing, in case of any blood transplant, this is used.  Every people have different HLA typing, so the person with same HLA typing can donate the blood to the person with same HLA typing. So I hope you understand, if you want more information and details on it then tell me in comment's. Q3) What is the purest form of sound? Ans- Beejakshara We hear many different type of sounds, but purest form of sound in beejakshara. Beejakshara is written in hindu texts as OM, shreem, hreem..... Etc. These sounds when you spell then some vibrations starts inside and you start to go into some super meditation.  No...

 Q1) What is a Black hole Ans- A Black is a region of space time where gravity is intense  Q2) How is a Black hole formed  Ans- a Black hole is formed when a massive star explodes, this process is called supernova, in this way a Black hole is formed. Did you know! Our can't form a Black hole because it is not too massive, thus when Sun explodes it is not called as supernova Q3) Where are the black holes present? Ans- The supermassive Black hole lie at the center of the Galaxies. Did you know! The name of the black hole present at center of MILKY WAY GALAXY is SAGITTARIUS A  Q4) Why black holes so intense Gravity  Ans- The gravity is so strong because matter has been squeezed into a tiny space. Did you know! The gravity in black holes are so strong that even light can escape. Hi viewers This is SSA from Learn it, Sai group, I try to spread information through my blogs and websites.

 There is a Black hole at the centre of the galaxy At center of MILKY WAY GALAXY a Black hole named SAGITTARIUS A  SAGITTARIUS A- Sagittarius A is a bright and very compact astronomical radio source at the Galactic Center of the Milky Way. It is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, visually close to the Butterfly Cluster and Shaula. Distance to Earth: 25,640 light years Radius: 22 million km Discovered: 13 February 1974 Coordinates: RA 17h 45m 40s | Dec -29° 0′ 28″ Constellation: Sagittarius Discoverers: Reinhard Genzel, Andrea M. Ghez, Harry Clive Minnett, Robert Brown, Bruce Balick  So for a galaxy there is a Black hole at the center  Hi viewers This is SSA from Learn it, Sai group, I try to spread information through my blogs and websites.

Conductors : Some substances readily allow passage of electricity through them, others do not. Those which allow electricity to pass through them easily are called conductors. They have electric charges (electrons) that are comparatively free to move inside the material. Metals, human and animal bodies and earth are conductors. Insulators: The substances through which electric charges cannot flow easily are called insulators. Most of the non-metals like glass, porcelain, plastic, nylon, wood offer high resistance to the passage of electricity through them. They are called insulators.
