Answer:
The magnitude of the average angular acceleration of the disk is .
Explanation:
Given that,
Angular velocity,
The disk comes to rest,
Time, t = 0.234 s
We need to find the magnitude of the average angular acceleration of the disk. It is given by change in angular velocity per unit time. So,
So, the magnitude of the average angular acceleration of the disk is .
The exact magnification of the objects is calculated by dividing the cinema. We calculate it by diving the erect image size by the object size. From the given above, we find the exact magnification by dividing 5.0 cm by 1.0 cm. Thus, the answer would be 5.
Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is inversely proportional to its
