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.
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
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...
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)...
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...
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..
