The number of particles n crossing a unit area perpendicular to the x

1.	The number of particles n crossing a unit area perpendicular to the x – axis in unit time can be written as n = p (n2−n1)(x2−x1) where n1andn2 are number of particles per unit volume between length (x2−x1). The dimensions of p are
Answer» The number of particles n crossing a unit area perpendicular to the x – axis in unit time can be written as n = p $\frac{(n_{2} - n_{1})}{(x_{2} - x_{1})}$ where $n_{1} a n d n_{2}$ are number of particles per unit volume between length $(x_{2} - x_{1})$ . The dimensions of p are

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
