A rational number is such that when you multiply it by \(\frac{{5}}{{2}}{\quad\text{and}\quad}\frac{{2}}{{3}}\) add to the product, you get \(-\frac{{7}}{{{12}}}.\) What is the number ?

A uniform rod is kept vertically on a horizontally smooth surface at a point O. IF it is rotated slightly and released, it falls down on the horizontal surface. The lower end will remain (A) at O (B) at a distance less than \(\frac{{l}}{{2}}\) from O (C) at a distance \(\frac{{l}}{{2}}\) from O (D) at a distance larger than \(\frac{{l}}{{2}}\) from O
Find the angular velocity of a body rotating wilth an acceleration of \({2}{r}{e}\frac{{v}}{{s}^{{2}}}\) as it completes the 5th revolution after the start
Two charged particles, having equal charges of \({2.0}\times{10}^{{-{5}}}{C}\) each, are brought from infinity to within a separation of 10 cm. Find the increase in the electric potential energy during the process.
Consider a wire of length 4m and cross-sectional areal \({1}{m}{m}^{{{2}}}\) carrying of 2A. If each cubic metre of the material contains \({10}^{{{29}}}\)free electrons, find the average time taken by an electron to cross the length of the wire.
