When an object falls through air, there is a drag force (with dimension M· L/T 2) that depends on the product of the surface area of the object and the square of its velocity; i.e., Fair = C Av2, where C is a constant. What is the dimension for constant C?1. [C] = M/T2. [C] = M/L33. [C] = M/L24. [C] = T•L/M5. [C] = T2•L2/M6. [C] = T•L2/M7. [C] = T2•L/M8. [C] = T/M9. [C] = M/T•L210. [C] = M/T2•L2
