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)



HOPE IT HELPED =D

u too ;D :D

Priceless:
@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! ;)

Friends:
OK now this is weird.
IF I +REP REKO IT INCREASE BY 2(IT HAPPEN TO ALL MEMMBERS)
IF I -REP HIM IT DECREASE BY 2 OR 1
