A tangent PT is drawn to the circle x^2 + y^2= 4 at the point P(sqrt3,1). A straight line L is perpendicular to PT is a tangent to the circle (x-3)^2 + y^2 = 1 Common tangent of two circle is: (A) x=4 (B) y=2 (C) x+(sqrt3)y=4 (D) x+2(sqrt2)y=6

The area of a triangle ABC is one unit. DE is a straight line parallel to BC , joining the points D and E on AB and AC respectively such that AD : DB = 1 : 6. The ratio of the areas of the triangles ADE and ABC is : एक त्रिभुज ABC का क्षेत्रफल 1 इकाई है | DE, BC के समानांतर एक सीधी रेखा है जो क्रमशः AB और AC पर स्थित बिंदु D तथा E को इस प्रकार जोड़ती है कि AD : DB = 1 : 6 है | त्रिभुज ADE और ABC के क्षेत्रफल में अनुपात ज्ञात करें |

Two S.H.M.s along the same straight line in the same direction and of the same period are given by the equations, x_1=3" "sin(4pit+pi/6) and x_2=4" " sin(4pit+pi/3) . The initial phase of the resultant motion is

A particle travels m a straight line, such that for a short time 2 s le tle 6 s, its motion is described by v= (4/a) m//s, where a is in m//s^2. If v= 6 m//s. when t= 2 s, determine the particle's acceleration when t= 3 s.

A secondary alkyl halide (A) hydrolyzes with alkali (B) in aqueous medium ismultaneously via S_(N)1 and S_(N)2 pathways with rate constants k_(1) and k_(2) , respectively. form kinetic data, it was found that a plot of = (-1)/([A])(d[A])/(dt) vs [B] is straight line with a slope equal to 2.7 xx 10^(-4) L mol^(-1) min^(-1) and intercept equal to 1.02 xx 10^(-3) . Minimum initial concentration of [A] = 0.2 M and [B] , i.e., [overset(ɵ)(OH)] = 0.5 M . The value of overall rate constant of the hydrolyiss of A (in L mol^(-1) min^(-1)) is
