two sound sources S_(1) and S_(2) are kept symmetrically about the centre of a circle as shown. The circle is divided is 4 parts. Both the sources are separated by a 8lamda//3 distance. Where lamda is wavelength of sound emitted by the sources. A detector is moving around the circle. How many times it will detect a minima in II part if S_(1) is leading S_(2) by phase of 2pi//3 ?

If the real part of (barz +2)/(barz-1) is 4, then show that the locus of the point representing z in the complex plane is a circle.

Straight line 3x-4y=4/(pi)sin^(-1)(a^(8)+1)+2cos^(-1)(a^(12)+1)-sec^(-1)(a^(2)+1),aepsilonR & 6x-8y=7 are tangents to a circle then the length of arc of this circle which makes on angle of 40/3 at its centre is

A circle S passes through the point (0, 1) and is orthogonal to the circles (x -1)^2 + y^2 = 16 and x^2 + y^2 = 1 . Then (A) radius of S is 8 (B) radius of S is 7 (C) center of S is (-7,1) (D) center of S is (-8,1)
