    Q18: B As speed and wavelength are directly proportional Q20: B As total internal reflection cannot occur at such a small angle of incidence... Q27: C.... As due to equal resistance, current will be divided equally!!

    Well it should be something like...... TV stations emit micro waves towards a satellite in space, the satellite then reflects the waves to the respective TVs in home, though this process of reflection etc must by highly directional and accurately aimed..... and the waves pass through clouds...

    At point P, draw a tangent to the optic fiber, and at the same point, draw a perpendicular line, which is the normal...... the angle between this line and the the line of incidence is the angle of incidence..... What happens there is .... Total Internal reflection, such that the incident ray...

    Coz pressure and volume are inversely proportional, thus by that they are connected by the formulae "Pressure=K/Volume", where k is the temp....... so u get a constant value of K in B, C and D..but not A...so A is ur answer...!!

    See..... Temperature, volume and pressure are connected by the formula: "Temperature= Pressure x Volume"..... so if u rearrange the values and take one of them constant at a time, ull see how they satisfy the 3 formula....

    There are basically 3 formula, Temp is directly proportional to pressure, Temp is directly proportional to volume... and the third is that Pressure is inversely proportional to volume... Hope it helps..:)

    Temperature is directly proportional to volume, thus it increases/decreases with volume.....

    You see, since we do not know the length of the spring when there is no load, so we are going to take length when 100g is attached to the spring as the initial point(like ASSUME that there is no load attached to the spring, and 100g is mass of the the spring, thus, its original length is...

    As the values given are for one of the particle emitted, therefore by using the formula; T=Q/I, you can find the time taken for one particle to travel to the screen...... Therefor, if u then divide "1" by the answer u get, u will get as to how many particle can reach in one second.... .. Hope it...

    Looking at The graph, it means that at 200g load, the extension is 2cm, where as on the other drawing, the lenght is 9cm, this means that the spring's actual length is 7cm( as if we add 2cm of extension, it would be 9cm)....... So if 100g is placed, the extension is 1cm, hence the total length...
