Starting to explore quantum mechanics, I read strong nuclear force that binds protons and neutron together in nucleus of atom, gives atom its mass. More binding energy means more mass of atom. Hence the query that, for example there are two magnets having a force F1. And we have the same size...
Sir, actually in a tank by the toricelli's law and also from bernoulli equation, we have outlet velocity as V= (2*g*H)^(1/2). In the case 2, I have closed the pipe exit partially with hand and observed a higher velocity than case 1, in practical. but when I applied the bernoulli...
In hydraulic lift utilising pascal law, larger piston area is A1 and the smaller piston area is A2
mass in = mass out and volume in = volume out (in-compressible),so
A1*x1=A2*x2 (let x1 and x2 are displacements of respective pistons)
A1*V1 =A2*V2 (on differentiation gives continuity...
