Can anyone explain me quasi equilibrium and non flow reversible in a simpler way? It is from thermodynamics and i am getting difficulty to understand it

I am rather confused what comprised of the thing that existed before big bang which later turned into matter after the big bang. Moreover, i read somewhere that matter are created spontaneously in the Higg's field. And this Higg's field was created after a fraction of seconds later the big bang...

Personally i support neo marxist theory...

Our professor said that when a metallic body or a conductor is inserted inside a gaussian sphere, it will not experience anykind of electric force? But i don't understand why? Any help will be appreciable.

Hi, I was wondering about a query on Coulomb's Explosion? Can Coulomb's Explosion occur in macroscopic level? I mean for a large bodies that are visible by naked eyes?

the heavier object falling faster than the lighter in the Earth's surface is due to the air resistance acting on the objects not due to the gravity as far as i know.

can u tell me if my upper and lower limits are right because still i am not getting the right answer..i think!

Ya i have solved using doppler effect. i was thinking if it can be used using relative velocity phenomena.

Homework Statement Hey i have a problem here with volume by cylindrical shells. i wanted to find the given volume of the solid obtained by rotating the region bounded by the curves x=1+(y-2)^2 and x=2 about the x axis. Homework Equations we tried to integrating 2 phi f(y) dy with upper...

Homework Statement I was thinking about the problem. There is a bat which is at rest and sends a sound of frequncy of 450 khz. another bat flying towards it hears it as a sound of frequency of 457 hz. i was trying to know the velocity of the second bat using simple physics formula or without...

I have a problem with the answer that if the ball is in constant speed when it is rotating then the answer is D. But i have read that for a rotating motion, there is always an angular acceleration and for a accelerating body a force must be acting. so shouldn't there be any frictional force...

i think if the object is ROTATING ( because i haven't understood if it is sliding means rotating or not) then PE= linear KE+ Rotational KE. maybe this can help us! i am not sure anyway..we had just learned about it.

what about the rotational kinetic energy?

thank you i got it now...what i did in my solution was that i didnt subtracted x=2 from the equation x= 1+ (y-2)^2. thanks for the help.

Homework Statement Find the volume generated by rotating the region bound by the given curves about the x axis Homework Equations x=1+(y-2)^2, x=2 The Attempt at a Solution i solved the problem using cylinder shells method. the solution equation i got was integration of...
