for theory it is better to use modern abc and ncert i am also a student i use modern abc and for numericals use hcv pradeep modern abc or u can do previous year questions of cbse HAPPY TO HELP.
intial U =0 we know that h=ut+1/2 at 2 h=½ gt 2 t=root of (2h/g) time taken ball reach the ground is t=root of (2h/g) THANK YOU
@ sugam as quartz is a piezoelectric material , then it can only be used in ultrasonic interferometer , besides that there is no other metals which can show this property . HOPE IT CLEAYS YOU ALL THE ...
Pseudo-force is a term used when defining behavior of non-inertial frames of reference, where applying this concept may simplify calculations by reducing them to Newtonian physics. More generally, a...
@ amarjyoti i am sorry , its not possible for me to provide all the answer of the dc pandey here , so, kindly tell me if u are facing problem in any perticular ques . then i can explain that question ...
given displacement of 12m towards east and 5m towards north then 6m vertically, from given data 12m east and it moves 5m north and 6m vertical so, 11 m in north. then sum of displacement = root of 12 ...
It is kept as such because the prongs vibrate sidewards, which means that the sound energy is transferred towards the sides of the prongs. Thus the prongs are kept in a vertical pane while doing the...
the fundamental frequency is =[(200000)^1/2]/2 =223.6 hz I think iam correct. if u have any further doubts please post them. thank u.
it is a simple substitution problem.. :) f=?, T=400N, l=0.5m, m(=mass/length)=10 -2 as it is a stretched string the highest frequency that can be heard is the fundamental note substitute the values n ...
@ sneha the locus of all the points of the medium which receives disturbances simoultaneously and are in same state of vibration are called as wavefront . every point on a wavefront act as a new...
Frimge width is given as: B = kD/d where k is the wavelength. Now given, B = 6000*2*10^-10/10. Again apply formulae in water but the new wavelength would become: k = 6000*(4/3)/1000
In rectangle due to all the lengths of the rectangle the direction of magnetic field is inside the loop. for longer sides the distance take b/2 and for breadth take l/2. and apply magnetic field...
the resonant frequency of a driven damped oscillator is equal to w = root(k/m) after it gets derived from, d^2x/dt^2 + 2cw dx/dt + w^2x = 0 or comare it. same for the damping ratio.that is c.
Hi, You can make a minp map of entire chapter and stick it on ur study table. Thanks
let the other string eqn. be, y = asin(wt + kx) put x=0 in first wave eqn. we get, y = asin(wt) equate both, asin(wt + kx) – asinwt =0 a(sin(wt +kx) – sinwt) = 0 a cannot be zero. solve then second...
