SUMMARY
The linear speed of the bottom of a test tube in a centrifuge can be calculated using the formula for centripetal acceleration, which is given by the equation \( a_c = \frac{v^2}{r} \). In this case, the centripetal acceleration is 5.3×104 times the acceleration due to gravity (9.81 m/s2), resulting in a value of approximately 519,930 m/s2. Given the radius (distance from the axis of rotation) of 7.3 meters, the linear speed can be derived as 1900 m/s, confirming the calculations presented in the discussion.
