Summary: why do group 15 share the same conduction band as the silicon atoms. In a n type extrinsic semiconductors the atoms of silicon are doped with the atoms of a gr15 element to increase the number of valance electrons in the semiconductor. But the reason given to me by my teacher and what...

but then the question would become if carbon has less nucleon than nitrogen why is the binding energy larger for carbon. neither of the nuclei is large enough that the nuclear forces from one nucleon wouldn't affect the other nucleons.

if binding energy per nucleon is proportional to the number of nucleons in the range of the nuclear force. then why is the binding energy for carbon 12 higher than nitrogen 14

If we have an object in space (deep space where it is under no other gravitational influence) and we push it a little so that it gains some velocity and after some time comes into the influence of a planet's gravitational field and crashes on it. Where is that energy from the crash coming from...

I was studying about atomic masses and realized that even if we say that the atomic mass unit corresponds to 1/12 of the mass of a carbon atom. why is it that even particular isotopes of elements have atomic mass in decimal values. 1/12 of a carbon atoms mass should equal to the mass of a...

While I was doing some practice questions it hit me "what is energy". I also don't understand how the formulas for potential and kinetic energy were derived. Was it due to their definitions or is there some reason behind their respective formulas.

Yes it sounds like I've lost it but I really want to build one. I was wondering is someone could guide me to useful resources. I'm currently reading some patents I found online to gain some more insight. Any help would be appreciated. Thank you.

I've been reading a book called hyperspace by D.R Michio Kaku. In this book he talks about unifying all the fundamental forces of nature (gravity , electromagnetic force , weak and strong nuclear forces.) My question is, what if they are not unified and we are just trying in vain. I don't...

What if we assume that every part (atom) inside the rocket accelerates simultaneously so that every thing in rocket A relative to itself doesn't move.

Assume that there are 2 rockets in deep space or a place where there is nothing around to compare their motion to. Rocket A starts its thrusters but the observer in rocket A doesn't know about it. So my question is, if rocket A is considered to be stationary by the observer then how can he...
