oncave focal length of a lens is 25cm the power of the combination in diopters is ...
a)-1.5
b) -6.5
c)=6.5
d)6.67
-1.5
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Angular momentum is associated with a particle in motion. The motion need not be rotational motion, but any motion. Importantly, it is measured with respect to a fixed point
Problem : A particle of mass, "m", moves with a constant velocity "v" along a straight line parallel to x-axis as shown in the figure. Find the angular momentum of the particle about the origin of the coordinate system. Also discuss the nature of angular momentum in this case.

thanx again the book is showing +6.5 option C... hope that the book is rong atm-1.5
nice explanation is this from intermediate book??
1. coversion of ferrenheight to kelvins ???
2. 1m = how many fts???
3. A hole in a p type semi conducter is???
a)an excess electron
b)a missing electron
c)a missing atom
d)a donor level??? (ans this wih explanation please)
Nah..not a chance, inter books are nightmare.. i have my own mini digital library...
.. has collected almost all topics of my interest from web.
You're doing your bachelors in ME from which university?
yaar ye do lens....ki jo combined power theel....cn u explain to me that the genral method

d)a donor level??? (ans this wih explanation please)
now what do we understand by the term classical physics???
One Question that comes often in Entry Test is
At what temp the Fahrenheit scale and Celsius scale shows same reading
Ans is .. at -40
-40 c = -40 F
ans this one tooClassical physics applies to Newtonian mechanics. It focuses on the theory that 'energy is continuous', which is true only at the macro level and not at the atomic and sub atmoic level.
the ratio of kinetic energy to total energy of the electron in an hydrogen atom is according to Bohr's theory is
a)1:1
b)1:-1
c) 1:2
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
