Angle as rotation of a ray.

When 20 gm optically active compound is placed in a 10 dm tube, in a 200 ml solution rotates the PPL by 30^(@) : (a) What is the angle of rotation if above solution is dilute to 1 litre ? (b) What is the specific angle of rotation if above solution is diluted to 1 litre ?

Lines L_(1) & L_(2) are rotating in an anticlockwise direction about the points A(-2,) and B(2,0) respectively in such a way that the speed of angle of rotation of line L_(2) is double as that of L_(1) . Initially equations of both lines are y = 0. If the angle of rotation of line L_(2) varies between 0 to (pi)/(2) , then the locus of point of intersection P of lines L_(1) & L_(2) is part of a circle whose radius is equal to
