Formulas of ncert class 9 of force and law of motion............. please answer fast

Answer»

d = total distance travelled / TIME required2.velocity = displacement / time 3.(a) acceleration = change in velocity / time(B) acceleration = a = FINAL velocity - initial velocity / time therefore, a = (v-u) / t4. three equations of motion:-(a) v = u + at....relation between velocity and time(b) s = ut + 1/2at SQUARE......relation between displacement and time(c) v square = u square + 2as......relation between displacement and velocity5. RATE of change of momentum = change in momentum / time( rate of change of momentum = mv - mu / t = m(v-u) / t = ma ) Hope it helps you ✌️❤️✌️❤️

How is organic matter seperated from seawage

Answer»

(or domestic WASTEWATER or municipal wastewater) is a type of wastewater that is produced by a community of people. It is characterized by volume or rate of flow, physical condition, chemical and toxic constituents, and its bacteriologic status (which organisms it contains and in what quantities). It consists mostly of greywater (from sinks, tubs, showers, dishwashers, and clothes washers), blackwater (the water used to flush toilets, combined with the human waste that it flushes away); soaps and DETERGENTS; and toilet paper (less so in regions where bidets are WIDELY used instead of paper).Sewage usually travels from a building's plumbing either into a sewer, which will carry it elsewhere, or into an onsite sewage facility (of which there are many kinds). Whether it is combined with surface runoff in the sewer depends on the sewer design (sanitary sewer or combined sewer). The reality is, however, that most wastewater produced globally REMAINS untreated causing widespread water pollution, especially in low-income countries: A global estimate by UNDP and UN-Habitat is that 90% of all wastewater generated is released into the environment untreated.[1] In many developing countries the bulk of domestic and industrial wastewater is discharged without any treatment or after primary treatment only.The term sewage is nowadays regarded as an older term and is being more and more replaced by "wastewater".[2] In general American English usage, the terms "sewage" and "sewerage" mean the same thing.[3][4][5] In common British usage, and in American technical and professional English usage, "sewerage" refers to the infrastructure that conveys sewage.[6]

Can you give me a clear note on class 10 evolution Of chapter heridity and evolution

Answer»

on When there is a change in the heritable characteristics of the progenies over a successive generation, it is known as Evolution.Jean Baptiste Lamarck was the first person to GIVE the theory of evolution. Thereafter this concept was made popular by Charles Robert Darwin in his famous book “The origin of species”. This theory that was made popular by his is known as the theory of natural selection or Darwinism.He states that evolution takes place through the process of natural selection. He states that traits may vary with respect to the phenotype variation. The traits differentiation is what DETERMINES the rate of survival. This trait of fitness and survival is heredity. This process on the BASIS of which changes OCCUR and that which is PASSED from generation to generation is called the evolutionary process.

Causes of air pollution and explain it

Answer»

te!!!Here is your answer:Automobiles: Automobiles are a source of toxic air pollution. Emissions occurring from exhaust system, fuel tank, as well as emissions of gases like hydrocarbons, carbon dioxide and lead oxides have added to air pollution.Industrial chimney waste:Petroleum REFINERIES emit gases like sulphur dioxide and nitrogen dioxide which are major pollutants. Acid vapours are emitted from chemical industries.Thermal power stations:Fly ash, sulphur dioxide, hydrocarbons, carbon MONOXIDE and particulate matter are common end products of thermal power plants that add to their pollution.Burning of garbage:The developing nations lack the infrastructure for proper garbage DISPOSAL. The residents often burn the trash in the open. It can range from food wastes to plastics and electronics. It is the chief source of CO2, particular matter, mercury and PAHs (polycyclic aromatic hydrocarbons). These chemicals may cause neurological diseases.Hope it helps u !!!Have a good DAY ^_^#bebrainly

Who could latent heat be explained from the graph

Answer»

there is a big stone and you have to lift that stone, you go and try to lift, do you think you could lift it easily(remember that it is little heavy and big), when you try to lift up by giving some energy it looks like it doesn't move despite you giving some of your energy and finally you really lift it hard by giving more energy than previous time now you can see that stone is lifting.similar manner all molecules has binding force with it, when you try to break it you need to spend some energy before completely break the MOLECULE from bonding that energy what we CALL “Latent heat”(How there is no movement in the stone up to certain energy level same manner, here we have no temperature and pressure changes in the medium(MEANS constant pressure and temperature) upto certain energy level. 1.Latent heat of melting or Latent heat of fusion - Breaking molecules in solid phase CONVERT it into liquid phase 2.Latent heat of condensation or Latent heat of VAPORIZATION- Breaking molecules in liquid phase convert it into gaseous phase.

What producers will you follow to study magnetic fields

Answer»

has ever taken the mythical journey to the centre of the Earth, but by studying the way shockwaves from earthquakes travel through the planet, physicists have been able to work out its LIKELY structure.Right at the heart of the Earth is a solid inner CORE, two thirds of the size of the Moon and COMPOSED primarily of iron. At a hellish 5,700°C, this iron is as hot as the Sun’s surface, but the crushing pressure caused by gravity prevents it from becoming liquid.Surrounding this is the outer core, a 2,000 km thick layer of iron, nickel, and SMALL quantities of other metals. Lower pressure than the inner core means the metal here is fluid.Differences in temperature, pressure and composition within the outer core cause convection currents in the molten metal as cool, dense matter sinks whilst warm, less dense matter rises. The Coriolis force, resulting from the Earth’s spin, also causes swirling whirlpools.This flow of liquid iron generates electric currents, which in turn produce magnetic fields. Charged metals passing through these fields go on to create electric currents of their own, and so the cycle continues. This self-sustaining loop is known as the geodynamo.The spiralling caused by the Coriolis force means that separate magnetic fields created are roughly aligned in the same direction, their combined effect adding up to produce one vast magnetic field engulfing the planet.
