Which option identifies the next step in the design process described in the following scenario? Olivia has just created a new toy using the engineering design process. The structure and function of the toy are fully understood, though further modifications may be necessary.

She will brainstorm with her team.

She will dismantle the product.

She will document the process.

She will create a model.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
