The linear expansivity of a metal p Is twice that of metal q. When these metals are heated through the same temperature, their increase in length is the same. Calculate the ratio of the original length of p to that of q

Four objects are being tested to see how they are affected by fluid friction. object w has a surface area of 4.5 cm2, object x has a surface area of 2.5 cm2, object y has a surface area of 6.2 cm2, and object z has a surface area of 3 cm2. which object would experience the most fluid friction?
