Question

Till now i haven't got anyone who can answer my questions.Its really disappointing to see this app mafe into a joke.

Here is another Question.
Derive Laws of Q mechanics String theory

​

Answer 1

Explanation:

derive which laws of qm and which math of string theory btw learn whats orbitals and stuff or u'll not understand

Answer 2

Saying that a string is under tension means that for all points X on the string, the string to the left of X is pulling the string to the right of X, and the string to the right of X is exerting an equal and opposite force on the string to left of X.

Now consider a string ABCDE, and suppose we are applying N's second law to the portion BD. Taking B as our point X, we clearly have a force from outside BD acting on BD. Similarly, taking D as our point X, we have another external force on BD. But if we take C as our point X, the force on BC comes from CD, and the force on CD comes from BC, so these equal and opposite forces are internal to BD and not the external forces whose resultant gives ma for BD.

Hope it helps this is derivation of 1 law
