When was E mc2 proven? 1905 Does the inertia of a body depend on its energy content? The mass of a body is a measure of its energy-content; if the energy changes by L, the mass changes in the same sepse by L/9 10%, the energy being measured in ergs, and the mass in grammes. […]

What is spatial polarization? The polarization process is likely to deepen urban socio-spatial divisions in two ways: the proportions of low- and high-income neighbourhoods can increase in the poorer and better-off parts of the city, respectively. Also, the social distance between these two parts, in absolute terms, can become more extreme. Do you think globalization […]

What is stream function and velocity potential? Introduction. The stream function, ,, is a function specially suited for dealing with two- dimensional flow while the velocity potential, f, is a function which may be. used with either two- or three-dimensional flow. What is unit for flow rate for gases? Because of this, meter flow rates […]
