When da trolley was accelerating, the blck experienced a backward force..........


but when it is moving with uniform velocity,


NET external force is ZERO.......


Hence no friction will act.........


PLz rate if satisfied!

First go through NCERT textbooks


Then try Morrison and Boyd. its gud to clear ur concepts.

Catalogs Discussion Forums -> Thermal Physics -> WHY GAS GAS MORE EXPANSION THAN LIQUID -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]

Gas particles are already loosely held and far apart from one another as compared to in liquids.


Hence even a small amount of energy is sufficient for them to expand

For two SPRINGS of stiffness k1 and k2-


in SERIES-    K = k1k2/ k1 + k2


in PARALLAL- K = k1  +  k2


Plz rate

Properties of a TRIANGLE-


sinA/a = sinB/b = sinC/c


In any triangle-


AC2 = AB2 + BC2 -  2AB .BC.CosB

The basic equations of motion-


v = u + at


s = ut + 1/2 at2


v2 - u2 = 2as

Yes, option (a) is correct,


If range has to be max.  according to-


R =( u2sin2#)/g


sin2# can have maximum value 1


Thus  sin2# = 1


2# = 90 degrees


# = 45 degrees

For   ORGANIC CHEMISTRY -


first go through NCERT books. Other good ones are-


Morrison n Boyd, Arihant's organic chem


PHYSICAL-  P Bahadur


INORGANIC - O P Tandon

This Post 2 points    (Olaaa!! Perrrfect answer.   in 1 votes )   [?]

The balanced equation is -


   4H2 + 3Fe3O4 ---- > 9Fe  + 4H2O3


hence the coefficient of H2  is  4.
