    A particle oscillates simple harmonically along a straight line with period 88 s and amplitude 828\sqrt{2} m. It starts from mean position then the ratio of the distances travelled by it in the 2nd2^{nd} second and the first second of its motion is (sin⁡45∘=12)\left(\sin 45^\circ = \dfrac{1}{\sqrt{2}}\right) (sin⁡90∘=1)(\sin 90^\circ = 1)

    The height of the liquid column raised in a capillary tube of certain radius when dipped in liquid AA vertically is 55 cm. If the same tube is dipped in similar way in another liquid BB of surface tension and density double the values of liquid AA, the height of liquid column raised in liquid BB is (Assume that angle of contact for both the liquids is almost same)
