    24 hrs r up......full time analysis phyx P12

    Ahmmmm...........20-20000hz is just the AUDIBLE SOUND FREQUENCY .... Sound does have frequency above 20000 in case of bats........ 20-20000 is what we can hear ..... I was nt sure but did D that young modulus one as all the rest were correct ithink :D

    its Gooners....nt gnoomers!!! Lol. :lol: I too wrote B fr repulsive Q! As fr Electric field strength the Q stated that hw to decrease that EFS....... as the frmula = E= V/D ,,,,,,, question stated that the V was low thus by frmula the D incres slightly the E decreases as the voltage was...

    Fringe spacing was 3 mm hence answer was 5.4 x10^-7 the kinematics equation was D in think as i did that by frmula = 2v /gt wat do u guyz reckon?

    Fr evapo Q it was true false true ...dnt rembr any option fr resistance, it was 4R........... As lngth doubled but volume is constant. As volume - height x area as height/lngth doubld hence fr sme volume the area is halved hence 2l/0.5A= 4R

    Guyz wat was the answer to the spring matress Q as to hw to change the something..dnt rembr... But I chose B!!!

    can u please tell the full Q . Dont really remembr this one!!! :)

    24 hrs r up......full time analysis phyx P12

    Yup uncertainity too wrote D.... As fr the repulsive force i think B was the answer as in C n D were in uniform electic field hence force wd remain constant at evry point hence D :D

    24 hrs r up......full time analysis phyx P12

    The Q stated that the V applied across the resistor was was very small i think hence if u use fomula E =V/D so increasing D slightly wd decrease the E as V provided is comparitively small as well.....do u guyz agree? As for the force graph ya i realize it was 4.8 as i only took tension across...

    Physics MCQs thread.

    guyz need help in Q relating current with no of electrons.....................Q says current of 4.8 A flows thru resistor R find the direction and no of electrons flowing thru R........................ Direction is opposite to currents direction but hw do we find the no of electrons...

    Guys wat was the answer to: 1) hw many iaomers fr c5h10 fr pie bond? 2) hw many chiral centers remaining after the K2Cr2O7 was aded ..... Probably the Q on the last page Q 38 ^^^^ 3)last question... Dnt remembr :oops: 4) what had same Electronegativity as Al? 5)wat was the graph fr PH values...

    Ambiguity of the term 'redox' reaction?

    according to our sylabus nd the defs in teachers notes.. redox is a reaction in which both oxidation nd reduction take place at the same time.. not only oxidation or reduction....................such reactions are called OXIDATION OR REDUCTION Reactions .............As in organic.. Its oxidation...
