Both liquids are immiscible. The length of the second liquid that should be poured in A so that first overtone of is in unison with fundamental tone of B is
Answer» A tube U - shaped has a uniform cross - section with arm length $l_{1}$ and $l_{2} (l_{1} > l_{2})$ . Tube has a liquid of density $ρ_{1}$ filled to a height h. Another liquid of density $ρ_{2} = \frac{ρ_{1}}{2}$ is poured in arm . Both liquids are immiscible. The length of the second liquid that should be poured in A so that first overtone of is in unison with fundamental tone of B is

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
