While the centrifuges are spinning, the net force on samples in the tubes is a. outward. b. inward. c. zero.

Short Answer

Expert verified
The net force on samples in the tubes while the centrifuges are spinning is outward.

Step by step solution

01

Identify the Context

Understand that the situation involves circular motion in a centrifuge. Here, centrifuges are spinning fast to separate samples on the basis of their densities.
02

Apply Physical Concept of Centrifugal Force

The centrifuge is spinning and hence creating a centrifugal force. This is a type of apparent force that acts on all objects when viewed in a rotating frame of reference.
03

Determine the Direction of the Force

The centrifugal force caused by the spinning centrifuge pushes objects or samples in the tubes away from the center of rotation. This force pushes the contents of the tubes outwardly.
