Thanks Adding individual forces would be very long, using PE it becomes easy... how should i do it when n tends to infinity

Suppose a n-sided polygon. Point particles of mass "m" each are placed in the corners of the polygon. How does the system of particles move if the only force anting between them is gravity? After how much time the bodies collide if n= 8 and n tends to infinity? Any suggestions are welcome...

Of course it is conserved. When ball hits the wall, the wall does not move because it is held at bottom and due to rigidity and elasticity of the material. The wall gives this back to the ball as reaction due to the action. That's why the velocity is same as it was when the ball was striking...

Any one can tell me why the momentum of the wall is 2mv while a ball collides it? wall is not moving.. a stationary body does not posses momentum. When the ball strikes with +p momentum the wall gives out equal and opposite reaction of -p momentum.

I am in dilemma, don't know whether to do mechanical or civil engineering. Civil engineering has lots of scope in my country but mechanical has got none. I have chance to study them both at scholarships. Which should i choose?

calculated it... H=(u^2 sin2A)/g

it comes out to be: T^2= ((2*pi)^2*r^3)/GM where r is radius and M is mass of central object. T is time period

Thank You D H Your help means a lot for a high school student.

The apparent acceleration due to gravity due to rotation of the Earth is given by: g(apparent)= g(standard) - R*ω^2*(cosA)^2 where R is radius of Earth at the point. A is angle made by the latitude with the equator and ω is orbital velocity. So, g is least at equator and max at poles because...

Thank You everyone for your answers. I do know C programming a bit and Qbasic Programming in detail. I will be learning FORTRAN in future. So, how should i design my program and could you give me some tips. Thank You Sakriya

What kind of Programming is it... I have got no clue. Could you guys give a bit detail

I don't know programming. Isn't there any simple way.

+9v and -9v is just the mentioning the electric potential difference. In that circuit the potential difference is 18V. It can be -3 or whatever you like it. It's just taking relative to the neutral or ground which is taken as 0V.

microwaves have wavelength ranging from 1 metre to 1 mm. So, they simply bend around the corners( Diffraction). Microwaves are not ionizing so i don't think they have any negative health effect and i haven't seen any good, reliable paper on microwaves stating that they have negative effect on...

potential energy just before the slide(at top of hill)= mgh= 320*10*300 let me give you some help with the second question. If the energy were not to be lost then the whole of the potential energy would have converted into kinetic energy and velocity at the bottom would have been v=sqrt(2gh)...
