    Gradient=rise/run.=sin(theeta)/lambdda dsin(theeta)=nlambda d=1/N (1/N)sin(theeta)=nlambda sin(theeta)/lambda=nN So,answer is A.

    Solved physics Paper 5??

    ...Just draw a box(label it with hall probe) and show connections to voltmeter and power supply ...or if u good at showing plane show the pplane perpendicular to field to get max voltmeter reading...and for second its true signal generator can produce ac...and we can vary frequency of ac..

    ,....Error can both be either positive or negative..so it does not matter whether u get positive or negative error because gradient(+_)error...

    mark scheme is correct..and this one is good question...when variable resistor would have zero resistance all current will flow through it not through resistor of 1.0k ohm PARALLEL TO IT, because current PREFER TO take shorter route and route in which there is no resistance....all current flow...

    work is said to be done when we apply force and object/mterial movess...here we are removing force nt adding...rubber is returning to its original position on its own...as force is not applied to get it to original position...D is wrong..no work is done..its zero....

    first q 26...find the time taken to produce one wavelength...for waveform P time is 4 seconds,,and for waveform Q time is 4.5 seconds..4,and 4.5 second represent 360 degrees...use options A,B,C,D time to find phase difference..for each waveform..and then subtract both of them...as for ..B..4.5s...

    why acceleration is max at max displacement...at max displacement kinetic energy is zero,velocity is zero..then how we can hve max acceleration...
