A formula for the drag force is F = dv² (found to be valid for a large regime of data), where F is the drag force, d is a constant (involving the area of the object, density of the fluid, etc.), and v is the relative speed between the object and the fluid. la) Rewrite the drag force equation in the form: 1b) In a plot of log F (y- log F 1b) In a plot of log F (y- variable) vs log v (x- variable), what do you expect to be the y-intercept? (...) log v + log (.….) variable) vs log v (x- variable), what do you expect to be the slope value?

Cylinders
A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.
Cones
A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.
