Why the people take tax on water reason? |
|
Answer» tion:Water taxThere are different kinds of tax on water, like tap water tax and VAT. The AIM of these TAXES is to encourage companies and households to use water more sparingly.Different water taxesThere are various different water taxes:tap water tax;value added tax (VAT);provincial groundwater tax;tax for installations on public land or water.Businesses and private INDIVIDUALS pay tax on tap water, VAT and tax for installations on public land or water. Provincial groundwater tax is only paid by water companies.No tax is levied on water used in emergency situations, e.g. water used by fire brigades to put out fires.Tap water taxTap water suppliers pay tap water tax to the Tax and Customs Administration. They recharge the tax to their customers. It is listed separately on water bills. The aim of this tax to encourage people to use tap water sparingly.How much tax someone pays depends on how MANY cubic metres of water they use. From 1 January 2015 water tax will only be levied on the first 300 m³. To find out the tap water tax rate for 2016, go to the Tax and Customs Administration website.VAT on tap waterThe government charges VAT on the consumption of tap water. This has been set at the low VAT rate of 9%. On your water bill you will SEE the VAT listed separately.Provincial groundwater taxWater companies have to pay groundwater tax to the provincial authorities. The rate of tax varies per province.Tax for installations on public land or waterMunicipalities can tax businesses and private individuals for installations on public land or water. Not all municipalities do so, and those that do charge different rates.MARK AS BRAINLIEST |

Explain newton fromula for velocity of sound |
|
Answer» Velocity of Sound in Gas (Newton’s formula)According to Newton, when sound waves PROPAGATE in air, compression and rarefaction are formed. He assumed that the process is very slow and the HEAT produced during compression is given to surrounding and heat loss during compression is gained from surrounding. So the temperature remains constant and sound waves propagate through an isothermal process.Derivation of Newton's FormulaAccording to gas law (Boyle's law),PV = constantwhere, P = pressure V = volume of air Differentiating above equation, we getpdv+vdp=0pdv=-vdpp=vdp/dvp=dp/-(dv/v)p=Bwhere, B is the bulk modulus of the air.If B is the bulk modulus of the air, v is velocity and ρ is the density, then, velocity is given by:v=√(b/p)v=√p/¶ Relationship of velocity or air with bulk modulus and density This is the required expression for velocity of sound in air.Calculation of Velocity of airNow, the velocity of sound in air using Newton's formula at NTP (NORMAL Temperature and Pressure) is given by:Pressure (P)= 1.1013 * 105 N/m2Density of air (ρ) = 1.293 kg/m3v=√(1.013*10^5)/1.023=280m/sCalculation of velocity of sound in air with Newton's formula |

A fighter planeflying horizontally at an altitude 1.5 km with a speed of 720 km flues over an Anticraft gun. At what angle should the shell be fired from the gun to hit the fighter plane with a muzzle speed of 400 m/s |
| Answer» TION:Given A fighter PLANE flying HORIZONTALLY at an altitude 1.5 km with a speed of 720 km flues over an Anticraft gun. At what angle should the shell be fired from the gun to hit the fighter plane with a muzzle speed of 400 m/s Given the horizontal distance travelled by the shell = distance travelled by plane. Height of fighter plane = 1.5 km = 1500 m Speed of fighter plane = 720 km / hr = 720 x 1000 / 60 x 60 = 200 m/s Let theta be angle with the vertical so that shell hits the plane. Muzzle velocity of the gun u = 400 m/s Time taken by shell to hit the plane = t So horizontal distance travelled by shell will be Uzt Distance travelled by plane = vt The shell hits the plane so the two DISTANCES must be equal. Now u sin theta t = v t THEREFORE sin theta = v/u So sin theta = 200 / 400 = 1/2 So theta = sin ^-1 ½ So theta = 30 degree Reference link will bebrainly.in/question/1382660 | |

What do you mean by the word peace ???? |
| Answer» TION:Peace is a time without any fights or wars. In a larger sense, peace (or peacefulness) can mean a state of harmony, quiet or calm that is not disturbed by anything at all, like a still pond with no dogsPeace within and among states is a goal of many people and organizations. One organization that was set up to BRING peace among the nations and try to make war a thing of the past was the League of Nations after World War I. When it failed to stop World War II, it was replaced by the United Nations which tries to make the world peaceful. This means that if any member is attacked or invaded by ANOTHER country without attacking that country first, the other members will come to help the country that was attacked first. This idea was used by the United Nations to defend both South Korea and Kuwait when they were attacked.Martin Luther King Jr. wrote in a letter he sent from the Birmingham jail that, "TRUE peace is not merely the absence of tension: it is the presence of justice." In other words, Real peace is more than just problems being gone: there must be fairness to have peace.Alfred NOBEL created an annual award, the Nobel Peace Prize, for the person who had done the most to bring peace to the world. | |
