i got anohter quesiton  :P same paper 2008 oct nov q3 all of it xP really sorry

thanks



HERE U GO::::

a) i]  = gravity* density*height
        = 10*1050*70
        = 735000Pa
        = 7.35*10^5 Pa
 ii]   pressure found at i] + atmospheric pressure
        =7.35*10^5 +1*10^5
        =8.35*10^5
b) P=F/A
    P=6.5*10^5
    A=2.5
    F= ?

   F=6.5*10^5 *2.5
   F=1.625*10^6

c)  As there r less number of particles in da less dense water (fresh water)

@adi.....big tym lol...believe me dats xactly wat i thot i ll du but i wz just curious...ders no doubt da xaminers r doubt...u nvr understnd wat dey want

@eamyzz.....4 da ques concerning energy conversions....da MS also said 2 ignore sound....lol....just du wat adi said  ;)

n abt da rulez....im confused 2 but i ll try 2 explain n any1 plz correct me if im wrong......

der r 3 things:  movement(motion of wire), magnetic field n current.....if any 2 of dem r occuring, den da 3rd wud b produced.....like in a generator....da wire is moved n der r magnets creating a magnetic field.....so a current is generated while in a motor.....ders da current n magnetic field producing movement of wire

now in a generator u wud use da right-hand rule 2 work out any of da three bcuz da current is induced.....n in a motor u wud use da left-flemings rule(usually 2 find da direction)

motors n generators r just examples By the way so apply in similar types of diags of machines given.....

i hope u understud....adi n shogun or anybody plz correct me if im wrong....thnkz...Take care...all da best! ;)

lol, wierd, i think its cuz- not all energy is transformed to k.e, i dont think this goes like tht law of cnservation of falling bodies (where at falling ,some of it is ke and some of it is pe.)

cuz the question says "the energy transoformations" and the mark scheme avoids by saying tht the whole pe was changed to something, as it only said transformed or decreased...

and heat is a must, as heat is lost due to friction, as any waste enrgy is lost mostly by heat.

thnkz shogun but it getz confusing at tymes wat da xaminers want den...neway as adi said just rite all da appropiate answers...lol ;) n thnkz neway :)

@Guthixol: gud luck 2 u 2..hope da ppr goes well....*fingers crossed* ;) :D
