pull as it imparts a component of force applied which goes into decreasing its apparent weight whereas in push there's a component which adds up to mg and makes it difficult to move.

u can't compare fiitjee with bansals :pit's like comparing a porche to a maruti 800

arihant n Ms chauhan .....stick to one book or else there'll be a pile of books of which no one will be useful

ya but in higher studies if u take up research

because two bonds are formed in the xy plane and the rest in 3d plane......that's why there is no space or dimension in which the fourth bond could be situated....

ans of Q2 is 100kg .....becoz breaking load=breaking stress* area....since cutting a wire won't chnge it's area n stress......therefore maximum load will remain same i.e. 100kg

45degree

first tell us what to find out???if u r looking fr values of x n y ....then x=-c(a+b)/a^2+b^2.....y=c(a-b)/a^2+b^2

q3....ans is 1) sqrt v^2-u^2/2

BOOKS SAY THAT S BLOCK ELEMENTS SHOW LUSTRE DUE TO FREE OR MOBILE ELECTRONS IN IT'S LATTICE. PLEASE EXPLAIN HOW CAN MOBILE ELECTRONS CONTRIBUTE TO LUSTRE OF A METAL?????

molarity is temperature dependent but is inversely proportional to volume and so to temperature from charles law......therefore it will be more for 25*C

a juggler tosses up a ball in the air with initial speed u. at the instant it reaches maximum height H, he tosses up a second ball with the same initial speed. the two balls will collide at a height ???? plzz explain it properly !!!

u can even check it out by taking out total time which will be 10sec. then find final velocity by vectors.

use equation of trajectory and solve it for uit's gonna be little complicated

IF ELECTRIC FIELD LINES AND MAGNETIC FIELD LINES EXIST.

WHY DON'T WE HEAR ABOUT GRAVITATIONAL LINES OF FORCES??

coordinate geometry by S.L loneyalthough it's quite old n there r many things u need not study from it. it's good for concept building. advice: approach a good maths teacher to understand very well. (Y)

it should be 45 ....maybe the question is wrong.

* is it cross product u r asking or dot product ??

fiitjee!!!!
