1.	Two vehicles are blowing horn at 3203 Hz. They are moving directly towards each other. A is moving at 10 m/s and B is moving such that he hears a beat frequency of 5 Hz at t=0. If they are 90 m apart at t=0, at what time (in sec) will the vehicles cross each other ? (Take speed of sound = 330 m/s)
Answer» Two vehicles are blowing horn at $\frac{320}{3} H z$ . They are moving directly towards each other. $A$ is moving at $10 m / s$ and $B$ is moving such that he hears a beat frequency of $5 H z$ at $t = 0$ . If they are $90 m$ apart at $t = 0$ , at what time (in $s e c$ ) will the vehicles cross each other ? (Take speed of sound = $330 m / s$ )

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
