Question

centrifuges are commonly used in biological laboratories for the isolation and maintenance of cell preparations. suppose a centrifuge rotates with constant angular acceleration. describe the tangential acceleration component of one of the blood samples that is located near the rim of the centrifuge. multiple choice the tangential acceleration is zero. the tangential acceleration is constant. it is impossible to determine what happens to the tangential acceleration of the blood sample since its location with respect to the center of the centrifuge is not given. the tangential acceleration constantly changes with time.

Explanation:

The formula for tangential acceleration is \(a_t = r\alpha\), where \(r\) is the radius (constant for a blood sample near the rim) and \(\alpha\) (angular acceleration) is constant. So \(a_t\) remains constant.

Answer:

B. The tangential acceleration is constant.
