Hello people, In an AC circuit, how is RMS current and Mean current defined as? What is the practical meaning of RMS current? Thanks in advance.

Hi, In vinyl radical, CH2=CH* (* -unpaired electron) what is the hybridisation of the carbon carrying the unpaired electron?

that would not be possible.. everything in this universe has mass.. however light or any electro magnetic radiation for that matter, in vacuum, moves with the same speed(3x10^8 m/s) forever..

Heating may or maynot affect the components of the organic solvents which have been adsorbed in the adsorbent. however, if the temp is high enough, then the solvent may vaporize.

thanks rainbow kid

can anyone give me a detailed explanation on how to derive equation for a straight line, which is made up of points, each point representing a complex number..// pls help

thanks guys...

Angular Momentum... Since magnitude of the angular momentum of a particle ( or body) depends upon the linear momentum of a particle( r x p)[ p- linear momentum, r - position vector] does it mean that a body rotating about a fixed axis( only rotational motion ) does not posses any angular...

dude, last time halleys comet was delayed by approx 520 days because of gravitational pull frrom Jupiter and saturn...

or using Newtons laws.. initial velocity = u at highest point v=0; v=u+at; a=g=10 m/s^2 u=10t; now from highest point. u=0; v=0-10t(- ve for direction); v= -10t;

gravity is a conservative force/./ when u throw the body and it reaches the max height, its velocity is 0( so KE is 0), whereas it has PE( which is = to mgh) when it reaches back to the point of projection, its KE will be equal to the PE at highest point( since gravity is conservative force)...

for one thing, the halleys comet would come to Earth a lot quicker, as it won't suffer any retardation due to jupiters gravitational pull...

Let A be the angle and u be the velocity of projection and g ( accel due to gravity) Range (R) = u^2sin A^2/2g Max Height(H)=u^2sin2 A/g sin 2 A = 2 sin A cos A equate R and H ( since they should be equal).. u will get sin A/cos A = 4 but sin A/cos A = tan A therfore A should be 76 degrees...

the angle is 76

the terms u have given are pretty much the same as my textbook... i want some better explanation so that i can understand what it really means..

Hi, i have a simple question.. What exactly are conservative and non - conservative forces? and why are some forces conservative and other are not? Thank you..
