Through the midpoint of each side of a triangle,a line is drawn
parallel to the bisector of the opposite angle. Prove that these
three lines are concurrent and that the point of concurrency is
collinear with the centroid and the incenter of the triangel. (hint
:use dilation)
Write equations of the lines through the given point parallel to
and perpendicular to the given line.
4x + 6y = 0, (7/8,3/4)
(a) parallel to the given line
(b) perpendicular to the given line
4 mol of a diatomic gas are taken through cycle ABC. AC is
adiabatic, BC is isochoric, and AB is isothermal. The volume at A =
2L and T = 300K. The pressure at B is 4 times less than at A. What
is the efficiency of the cycle? Show pictorial as well
