    PAPER 1 phisics Multiple choise doubts

    for q.35 as we increase the resistance of varible resistor so the voltage across it will also increase this means dat the voltage across XY will decrease (as they r in series and voltage divides proportionally b/w the resistors according to their resistances) so v r left wd either option C or...

    PAPER 1 phisics Multiple choise doubts

    for q.36 we will find the potentials or voltages at X and at Y then we will subtract them at X the potential is 2 - (2/3) = 4/3 (V) at Y the potential is 2 - (4/3) = 2/3 (V) nw we will subtract Y from X (4/3) - (2/3) = 2/3 (V) so our ans is A

    Maths AS PAPER 1 HELP PLEASE

    In 5 - 3cos2x (0<x<pi) 5 means here we will start the graph- it will b treated lyk in normal graph as x-axis 3 means da amplitude of the graph 2 means no. of waves to draw in the range (0<x<2pi) as da range abv is gven till pi so as 2 waves will form in 2pi so we will show 1 wave...

    PAPER 1 phisics Multiple choise doubts

    for q.19; initially da twig has P.E. as mass is unknown so we will take it as m so initially: P.E. = m.g.h P.E.= (200).(10).(m) P.E. = 2000m (J) as 40% is lost as heat so we will subtract it lyk: first calculate 40% of 2000m its = 2000m x 40/100 = 800m as dis 800m is lost so we will subtract...

    PAPER 1 phisics Multiple choise doubts

    for q.18 we'll use two formulas; firstly: P.E = m.g.h so the energy is coming P.E = (1.3 x 10^9) x (10) x (2) P.E = 2.6 x 10^10 now we will calculate power by formula; P = E/t as da tym is 1 day so we will convert it to sec to get t = 24 x 60 x 60 t = 86400 s now putting in da values P = (2.6...

    PAPER 1 phisics Multiple choise doubts

    for q.11 da formula ov elastic collision is applied that is; Relative speed of approach = relative speed of departure Ua - Ub = Vb - Va then according to da directions v put da signs lyk: (+ Ua) - (- Ub) = (+ Vb) - (+ Va) so finally v get: Ua + Ub = Vb - Va that is part A

    PAPER 1 phisics Multiple choise doubts

    for q.7 we will count da waves that is coming about 8.5 waves then we will divide it by 60 ms becx for 1 box it is 10 ms so we've got 6 boxes so 60 ms and so we get 141.7 waves/sec as they've askd approximate so itx B 140 waves/sec in other words 140 Hz
