I think,
The water will experience a force backwards (and that force is noting but a psuedo force -ma ).
And the level of water will be more in the rear side of the glass.An equillibrium will be establised between the water's restoring force and the pseudo force.
If u hav taken an undergraduate course on elecrodynamics then u may hav come across an expression of the current flowing through a circuit containg an inductor , resistor and an AC source in series as
I0 = V0/sqrt(R2+(ω L)2)
...ω is the freq. of the source...L the inductance
And phase...
talking first about conduction in DC ,we can understand it by considering a straight metal wire being kept in a uniform electric field. Clearly almost every electron in the conductor experiences this electric field simultaneously and starts to accelerate . But presence of ions only allow them to...
Infrared heats a body but UV heats less!
If we consider two bodies of indentical properties (and temperature) and we apply radiation on them with different EM wave ,One with Infrared and the other with UV ray,we find that the body exposed by IR has more temperature increase with respect to...
sorry but there is an error in your problem, a quasi static process cannot be both isothermal and isobaric. if it happens then volume will be constant as pV=nRT ,condition if number of moles not changes(closed system).
First of all coefficient of restitution is
C=v/u simply in case of bouncing of a rigid ball on a rigid surface.Not , C=(v-1)/u.
Then, also this paradox arises as you mentioned .
we must not forget that we apply Newton's laws in some idealized cases. And this application may seem to be...
OK, I got your point.Really it is quite satisfying.
But now take the similar case when a body is in just a simple circular motion. The instantaneous velocity and tangential velocity is same here.This velocity is always perpendicular to the tension. Now going with your same logic, suppose...
may be you are right,but ,truly speaking I am not getting you. I am just a beginner. It will be my privillage if you can just ellaborate this concept and clear the errors in my thinking.You can suggest some links also .
I saw this link . "the involute of circle " ,this stuff really helped me...
the direction will change , but magnitude should remain same as the tension cannot change the perpendicular component of the velocity because tension is always perpendicular to the per. comp. of velocity at any instant.
thanks for your replies .All the statements made by you are absolutely right. Surely the speed of the revolving body will increase as the tension is doing work on it. The attachment given by "rcgldr" is OK. but have a look in this attachment below. the instantaneous velocity is (here in RED)...
I have problem to see clearly the case of rotation of a body about a point with decreasing radius.this can be viewed as a body being rotated about a point with the help of a thread which passes through a hole in a disc and the thread is being pulled to apply a tension and gradually to decrease...
