any one having HCV part1 can u pls do problem no. 21&28 from the chapter friction
page no.-98&99.thought of typing the question but they have figures which i cant draw here so please do them and give soln

A boat takes time 't' to go from A to B & '2t' to go upstream frpm B to A speed is v
speed of water is u .find reln betn v &u
|
|
|
|
a train A runs from east to west &another train B of same mass runs from west to east at the same speed along the equator.A presses the track with a force F & B
presses the track with a force K. wat is the rel'n bet'n the 2 forces

hello jay
well as u know newtons laws are not applicable in non inertial frames
to over come this we suppose that imaginary forces act on a body in a non inertial
frame so that we can apply newtons laws
ex:if a body of mass 'm' moves in a non inertial frame which has an accln 'a' wrt an inertial frame then to find net force on the body wesubtract 'ma' from the net force which it has in an inertial frame.here '-ma' is the pseudo force & even the above give n example if u still don understand read HCV.

sir i have not done HCV perfectly till now but i want to do it along with GMP or YGFILE(both are old) so wat shud i do

A block of mass 'm' is kept on a rough horizontal surface.coefficient of static friction
is 'u'.The block is to be pulled by applying a force to it. What min force is needed to
slide the block?direction of this force.
can you also give conditions 4 slipping &sliding of a body

answers are acetic acid>phenol
another questioncorrect acidic order
(a)HCN (b)ETHANOL (c)water
explain your answers
|
|
|
|
1.which group has more -I effect cyanide or nitro
2.which is more acidic & why (a)phenol& (b)acetic acid

till now i have not prepared seriously 4 the jee
but now i want to give my best 4 it
i am an AP state board student .Iam prep from following books:
maths:trigonometry&geometry{S.L.LONEY}
REMAINING PART FROM BRILLIANT OLD ELITE PACKAGE
physics:resnick&halliday
chemistry:org:S.N.SANYAL
inorg&phy:objective chemistry by p bahadur
please suggest me a plan to do it as iam not confident in most of the topics
though ive read them iam failing to recollect
so please help me
