1.	Three waves from three coherent sources meet at the same point. The Amplitude of each wave is A0. Intensity corresponding to A0 is I0. At a point, the phase difference between the first wave and the second wave is 60∘and the path difference between the first wave and the third wave is λ3.

Answer» Three waves from three coherent sources meet at the same point. The Amplitude of each wave is $A_{0}$ . Intensity corresponding to $A_{0}$ is $I_{0}$ . At a point, the phase difference between the first wave and the second wave is $60^{\circ}$ and the path difference between the first wave and the third wave is $\frac{λ}{3}$ . The first wave lags behind in phase angle from the second and the third wave. The resultant intensity at this point is

A parallel-plate capacitor having plate area A and plate separation d is joined to a battery of emf E and internal resistance R at t=0. Consider a plane surface of area A/2, parallel to the plates and situated symmetrically between them.

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
