The 5-kg uniform rod AC is attached to springs of constant k = 500 N/m at B and k =620 N/m at C, which can act in tension or compression. If the end C of the rod is depressed slightly and released, determine
(a) the frequency of vibration,
(b) the amplitude of the motion of point C, knowing that the maximum velocity of that point is 0.9 m/s.
A double convex lens has equal curvature radii of 35 cm. An object placed 30 cm from the lens forms a real image at 136 cm. What is the refractive index of the lens?'
