Final answer:
The acceleration at the end of a test tube that is 10 cm from the axis of rotation can be calculated using the formula for linear acceleration.
Step-by-step explanation:
The acceleration at the end of a test tube that is 10 cm from the axis of rotation can be calculated using the formula for linear acceleration:
acceleration = radius * angular acceleration
However, in order to provide an answer specific to your question, I would need more information. Please provide the angular acceleration or any other relevant details so that I can assist you further.
