To find the average angular acceleration in the first 10 minutes, we need to calculate the change in angular velocity divided by the change in time. From the graph, we see that the angular velocity at 0 minutes is approximately 3.5 rad/s and the angular velocity at 10 minutes is approximately 8.5 rad/s. Therefore, the change in angular velocity is 8.5 - 3.5 = 5 rad/s. The change in time is 10 minutes, which is equal to 600 seconds. Therefore, the average angular acceleration is 5/600 = 0.00833... rad/s2. Choice C is the closest to this value.
