    Unit of mean square velocity

    OOOPS..! yeah sorry i made a mistake .:redface: the unit for velocity is m/s.. but is the unit of mean square velocity really m2/s2 ? (i mean, i just want to confirm. because in my book the unit of mean square velocity is given as m/s...:confused:... so the book must be wrong .)

    Unit of mean square velocity

    hi... we know the unit of velocity is m/s2 and while calculating the mean square velocity we find the average(or mean) of the 'squares' of the given velocities. then the unit of MEAN SQUARE VELOCITY should be 'm2/s4' then how come its unit is also m/s2 and not m2/s4 ?

    Meaning of symbols in given equation

    "Work (in joules) = (4.18 joules per calorie) x Q (in calories)" Wow really its clear now ! Thanks a lot

    Meaning of symbols in given equation

    well yeah I know in S.I. 'J' stands for joule... but in the equation W=JQ ; if we consider W(work) and Q(energy) in the same units, then here J seems to be some constant with no units and no dimensions ! [as 'J' relates W & Q with a multiplication and not addition or substaction] the...

    Meaning of symbols in given equation

    In my textbook, under the subtopic 1st law of of Thermodynamics, an equation is given as foll : W=JQ where W=work done ;Q=heat supplied but they have not mentioned what is J. please could someone tell me what exactly 'J' stands for in this equation

    How do bonding and antibonding MOs coexist in molecular systems?

    hello.. i have checked various resources but am unable to get a clear idea of how bonding and antibonding MO exist simultaneously? [following that bonding MO results due to in phase overlapping of atomic orbitals while antibonding MO results due to out of phase overlapping]

    Crest and Trough Interference - Light Wave Explanation

    when light waves interfere, it is said that when the troughs of both the waves (say) coincide, destructive interference takes place. it means that the waves have min. energy at crest and max. at crest. i don't understand how this could be, following that both(crest and trough) have the same...
