Considering Earth's potential as 0 is nothing but an assumption.We assume that Earth  is a collection of infinte negative charge and it can even supply more charges to it.As earth has such a huge amount of negative charge with capacity to be supplied with even more any other body will  be positive w.r.t Earth.Hence we assume its potential to be zero.

Aliter

As Earth can store unlimited charge its capacitance is infinity

Q=CV

=>C=Q/V

As C is infinity V has to be 0.

Mass of the gun, M= 100 kg Mass of the shell, m= 0.020 kg Muzzle speed of the shell, v = 80 m/s Recoil speed of the gun = V Both the gun and the shell are at rest initially. Initial momentum of the system = 0 Final momentum of the system = mv - MV Here, the negative sign appears because the directions of the shell and the gun are opposite to each other. According to the law of conservation of...

Amount = Rs.(30000+4347) = Rs.34347 let the time be n years Then,30000(1+7/100)^n = 34347 (107/100)^n = 34347/30000 = 11449/10000 = (107/100)^2

You need to mention your domicile state and category as each state has different cut-offs under AIQ quota and state quota(categories under state too have different cut-offs), with  561 marks your expected rank can be between 19758 - 21908. Cut-offs change every year and based on various factors like top NEET score, difficulty level of paper, number of candidates appearing etc. You can use our...
Given:7g of N2 i.e 0.25 moles 8g of Ar i.e 0.2 moles Total pressure=27bars Explanation: we know that moles=Given mass /molecular mass Now we know that partial pressure is equal to product of moles fraction and total pressure in closed system therefore, mole fraction of Nitrogen gas=0.25/0.45 Now partial pressure=(0.25/0.45)27 =15bars
Fehling's solution is a chemical reagent used to differentiate between water-soluble carbohydrate and ketone functional groups, and as a test for reducing sugars and non-reducing sugars, supplementary to the Tollens' reagent test.

True will come as the cube of 2 is 8, 4 is 64, 6 is 216 etc.....
