    Here Resistors are connected in parallel, so there will be different currents in the circuit... we are asked for the 9Ω resistor so I = V/R I = (3-1.2) / 9 = 0.2A

    18) power output P=IV 23 x 320 =7360 W power input Power=energy/time so P=mgh/t and m/t is= 200 kgs-1 so 200 x 9.81 x 8 =15696 W output/input x 100 7360/15696=0.468 nd 0.498 x 1ooo =46.8 so answer is D

    Sorry Zarah for the delay :( 11) 15) Power = Force * velocity Power = (1000 + 1000*10) * 0.5 Power = 11000 * 0.5 Power = 5500 W = 5.5 kW 17) P = ρgh (110000 - 100000) = 1020*9.81*h h ≈ 1.00 mm

    10) Force = mass times acceleration total mass = 4m so, F=4ma a=F/4m F(Y)=3m x F/4m = 3F/4 40) Ok..This is Tricky But involves Math Skills..!! Look Proton Has Charge of (+)1.! We need to end Up at One Using Values of Up quark and Down Quark.! If U Take 2 UpQuarks = (+)(2/3) * 2 = (+)(4/3) And...

    Here R = V/I so, as R increase, V increases and I decreases... So here Variable resistor is connected in series with other resistor, so its resistance would decrease hence V decreases And Ammeter readings will be unchanged as it is in parallel... :)

    B is the answer ? If yes, then use the formula : 0.5 * F * extension 0.5 * 17 * (30 * 10 ^-2) = 2.6
