SUMMARY
The acceleration at the end of a test tube in a centrifuge rotating at 4000 RPM can be calculated using the formula a = rω². In this case, the radius (r) is 0.1 meters (10 cm), and the angular velocity (ω) can be derived from the RPM value. Converting 4000 RPM to radians per second gives ω = 418.88 rad/s. Substituting these values into the equation yields an acceleration of approximately 17,600 m/s² at the end of the test tube.
