1.	A source of sound (of frequency f0 ) and an observer are moving towards the intersection point P following two straight lines inclined at 60∘ with speeds v/2 and v/3 respectively where v is the speed of sound in air. If frequency of the sound heard by the observer when he reaches point P (Assume that the observer reaches P before source) is nf0, then the value of 3n is [Answer upto two decimal points]
Answer» A source of sound (of frequency $f_{0}$ ) and an observer are moving towards the intersection point $P$ following two straight lines inclined at $60^{\circ}$ with speeds $v / 2$ and $v / 3$ respectively where $v$ is the speed of sound in air. If frequency of the sound heard by the observer when he reaches point $P$ (Assume that the observer reaches $P$ before source) is $n f_{0},$ then the value of $3 n$ is [Answer upto two decimal points]

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
