Two coherent narrow slits emitting sound of wavelength λ in the same

1.	Two coherent narrow slits emitting sound of wavelength λ in the same phase are placed parallel to each other at a small separation of 2λ. The sound is detected by moving a detector on the screen E at a distance D(>>λ) from the slit S, as shown in figure (16-E6). Find the distance x such that the intensity at P is equal to the intensity at O.
Answer» Two coherent narrow slits emitting sound of wavelength $λ$ in the same phase are placed parallel to each other at a small separation of $2 λ$ . The sound is detected by moving a detector on the screen E at a distance $D (>> λ)$ from the slit S, as shown in figure (16-E6). Find the distance x such that the intensity at P is equal to the intensity at O.

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
