Consider an ideal gas enclosed in a cubical vessel of edge L. Take a corner of the vessel as the origin O and the X-,Y-, Z- axes along the edges (figure 1). Let A1 and A2 be the parallel faces, perpendicular to the X-axi..

Consider an ideal gas enclosed in a cubical vessel of edge L. Take a corner of the vessel as the origin O and the X-,Y-, Z- axes along the edges (figure 1). Let A 1 and A 2 be the parallel faces, perpendicular to the X-axis. Consider amolecule moving with v..

An equation of one variable and of first order (i.e., its highest power is one) is called a Linear equation. Such an equation has only one solution. A solution is also called the 'root' of the given equation.An equation of one variable and of first order (i.e., its highest power..

Solve the system of equations by using the multiplicative inverse of a matrix. 2 x + y - z = - 1 x - y - 2 z = - 2 2 y - z = 2 => (0, 2, 0) or (1, 0, 2) or (2, - 1, 2) or (- 1, 1, 0)..
