What is the method used to recharge the groundwater? Subsurface Groundwater Recharge Wells Recharge or injection wells are subsurface groundwater recharge techniques used to directly discharge water into deep water-bearing zones. Recharge wells can be cased with the material covering the aquifer. What is the main source of groundwater Class 6? When rain water and […]

How is science used in policy? Scientists attempt to achieve their goals by either providing informa- tion (i.e., educating policymakers about science) or by championing particular policy outcomes (e.g., by using persuasive arguments, political pressure, or positive incentives to achieve particular policy goals). Why do we need science policy? Policy sometimes sets the rules of […]

How would air resistance affect the total amount of energy that exists? Even if air resistance slows down the ball, the potential energy is the same (Mb x g x H). But if air resistance is in the way, not all of the potential energy can be converted to kinetic energy. When that happens, the […]

What happens to current when resistance is increased? The relationship between resistance and the area of the cross section of a wire is inversely proportional . When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result. Why current can kill you? While any […]

What is a system of linear equations in two variables? A system of a linear equation comprises two or more equations and one seeks a common solution to the equations. In a system of linear equations, each equation corresponds with a straight line corresponds and one seeks out the point where the two lines intersect. […]

Where is the strongest part of an egg? The egg is strongest at the top and the bottom (or at the highest point of the arch), which is why it does not break when pressure is added to both ends. The curved form of the shell also distributes pressure evenly all over the shell rather […]

Can you swear at police UK? There is also an offence of using obscene and profane language in the street to the annoyance of residents. However, a person is only likely to be arrested for this offence if the behaviour occurs in the presence of a police officer. Do police swear allegiance queen? swear their […]

How Moon is useful to us? The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet’s wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years. How does […]

What is the difference between absorption and desorption? As nouns the difference between absorption and desorption is that absorption is the act or process of absorbing or of being absorbed as, while desorption is the process in which atomic or molecular species leave the surface of a solid and escape into the surroundings; the reverse […]

How do you measure drop by height? Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling. How do you measure the height […]
