I was taught this in school but my teacher could not explain why the band splits again with decreasing atomic distance. Also, then i wondered how do you explain the fact the it splits again nicely into 4N states for the valence band and 4N states for the conduction band? Could some one help...

This calculation seems to have error

What is wrong? and Where? What do you mean by confusing velocity and acceleration? Find the effective acceleration for both Y and X axis, then use the linear laws of motion to get the final velocity components? Why is this wrong?

Thank you very much for the above answers, but regarding the cars. So friction = ma, because friction is the only horizontal force. Since friction is = to Fapplied, coz it is its reaction, and there are no other opposing force on this friction, it becomes the resultant force. Thus, as soon as...

Oh Thank the both of you guys so much. Though how exactly inertia reduces the NR force explained in terms of forces (makes me think if inertia is a force), i am still not very sure. But the idea is intuitive and i appreciate you guys explaining it for me. Another question, if there is a...

Does your reasoning apply for cars at the top of the bridge? It seems like for the question, NR is still less than the weight. So its due to inertia? Coz at the top of the motion, the forces act like on a straight line motion, mg is vertical, so shouldn't NR be = to Mg coz its like on the...

1. A car of mass 1500kg moving at constant speed of 80km/hr passes over a humpback of a bridge of radius of curvature r. The car remains in contact wit the road as it passes over the top. a) Express N, net force exerted by the car on the road, in terms of r. b) Determine the minimum...
