Question

Mark the wrong statements: 3 False statements 1.A coordenate system is an artificially imposed grid that you place on a problem in order to make quantitative measurements. 2.Not necessarily a Coordenate System have perpendicular axis. 3.To decompose or resolve a vector is to find its components in a particular Coordenate System. 4.The x-axis is horizontal and point positive to the right. 5.In a Cartesian Coordenate System the quadrants are counted counterclockwise from the positive x-axis. 6.The absolute value of the x component of a vector is the magnitude of the vector. 7.A scalar is a positive number (with units).
