A source of sound and detector are placed at the same place on ground.

1.	A source of sound and detector are placed at the same place on ground. At t = 0, the source S is projected towards reflector with velocity V0 in vertically upward direction and reflector starts moving down with constant velocity v0. At t = 0, the vertical separation between the reflector and source is H(>v20)2g). The speed of sound in air is v(≫v0). Take f_0 as frequency of sound waves emitted by source. Based on above information answer the following questions. Frequency of sound waves emitted by source at t=v02g is
Answer» A source of sound and detector are placed at the same place on ground. At t = 0, the source S is projected towards reflector with velocity $V_{0}$ in vertically upward direction and reflector starts moving down with constant velocity $v_{0}$ . At t = 0, the vertical separation between the reflector and source is $H (> \frac{v_{0}^{2})}{2 g})$ . The speed of sound in air is $v (≫ v_{0})$ . Take f_0 as frequency of sound waves emitted by source. Based on above information answer the following questions. Frequency of sound waves emitted by source at $t = \frac{v_{0}}{2 g}$ 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
