12th science physics problem of occilation
theoriginal169 replied to rahul157's topic in Homework Help
we should know the periodu other wise we cant know the answer. -
ill check them thank you. Does their book have challenging exercises?

What should be the acceleration when a object is pushed by hand ?
theoriginal169 replied to Zirok's topic in Physics
necessary data 1 mass of object 2 fraction between mass and floor 3 how much time the force will be applied 4 the diagram of force-time or probability density of that diagram( to find mean value and standard deviation) but for more precise solution the diagram would be good. 5 G 6 the angle between the force vector and object 7 the cohesion between hand and object 8 the air pressure of environment also shape of object to calculate the boundary conditions of air. 9 the place of the experiment to calculate the centrifugal effect of earth. bla bla bla in conclusion you cant know the exact acceleration unless you have an enormous data. i can only tell you the possibilities. -

what is the period T of system? -
i got that book vol2. i can understand it. and it has detailed proofs which i didn't saw at my previous book . so thank you good advice. but its a little old so i dont know is it a problem or not?

the 3d harmonic oscillator potential is super spherically symmetric what does it means. Wikipedia didn't help me so much.

you didnt get my question so i try to explain it ...

calorimeter calculates the heat. q=mc delta t t is the tlast - t0 ideal clcmeter doesnt gives any heat to outside or gets from outside . so it only measures your reactions heat. for example you make a exothermic solution. so you need to measure your solutions c m and the time of reaction you ll find q(enthalpy). but you cant know the c so you make the reaction in clcmeter it ll show the q.

you are talking about the quantum number for the composite systems there is no place for m at this situation . H=-gamma b0 Sz is the Hamiltonian matrix for the spin at the magnetic fields . and you can change the axis whit Schrodinger equation ih dx/x =H x where is x is eigenspinor .

h2s or h2s2 i cant remember but its odor is like a shit we used it alot at chem 102. but i don't remember how to make it.

What would happen if a black hole swallowed an anti-matter black hole?
theoriginal169 replied to padren's topic in Physics
is that possible that they would make a worm-hole. -
hormones genetics reproductive system phenotypes the differences at blood count etc.

Whats the most dangerous chemical you have used / seen?
theoriginal169 replied to RyanJ's topic in Applied Chemistry
cn solutions are extremely dangerous also they can pass through the gloves. -
its a some kind of power series expansion

Underbraces in mathematics - what do they mean?
theoriginal169 replied to seriously disabled's topic in Mathematics
it seems like Plancherel s theorem you can exchange functions if f(x)=sigma(g(x)exp(ikx)) here you can exchange f and g while changing i to -i . -
you just want to believe but .... dont try to make your beliefs scientific.

at my question a is x x-a is x0 why? what changes in f(x+x0)
-
f(x + x[math]_{0}[/math])=[math]\sum[/math]1/n! x[math]_{0}[/math]^n(d/dx)^n f(x) i saw this at my book but didnt understand .

no 1 says that planets have no gravity so faster than light is kinda this.

its beyond the nature you cant seek the unnatural phenomena outside the galaxy unnatural is unnatural.

at library there are a lot of books i got lost at there.

DNA dyes they are extremely dangerous and cancerous. -
i am physics student but at 1 am 2nd grade but i want to learn QM faster so i finished that book . and what next? qm has a lot of sub subjects and i don't how i choose the path ill go. Merged post follows: Consecutive posts mergedhttp://www.amazon.com/Modern-Quantum-Mechanics-Revised-Sakurai/dp/0201539292 in my school at advanced qm lectures this book is used. i am good at math(calculus diff linear algebra) and i now basics of qm so can i handle ha book.

i have finished reading introduction to quantum mechanics by David griffiths and solved all of the problems so what book do you suggest to me next ?
