If you had a liquid whose density was three-fifths that of mercury, how tall would you need to build a barometer to measure atmospheric pressure in a location where the record pressure recorded was 750. mm Hg

Answer/// he concludes that the atom particles can be broken due to the paddle wheel being moved by particles coming out of the metal;

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
