A spring has a natural length of 14 cm. If a 22-N force is required to keep it stretched to a length of 26 cm, how much work W is required to stretch it from 14 cm to 20 cm? (Round your answer to two decimal places.)

A bi-convex lens is formed with two plano-convex lenses as shown in the figure. Refractive index n of the first lens is 1.5 and that of the second lens is 1.2. Both curved surfaces are of the same radius of curvature R = 14 cm. For this bi-convex lens, for an object distance of …

If the perimeter of a semi-circular protractor is 108 cm, find the diameter of the protractor.

Given: Radius of inner circle = 7 cm. Radius of outer circle = 14 cm. Angle made by sector = 40 o. Area of sector OAC = 40 o 360 o × π r 2 = 1 9 × × 22 7 × 14 2 = 68.44. Area of sector OBD = 40 o 360 o × π r 2 = 1 9 × × 22 7 × 7 2 = 17.11. Area of the small region A B D C = Area of the small sector O A C – Area of the small sector O ...
