# The Mystery of Windmill Blades Rotation Time

## The blades of the windmill turn on an axis that is 20 feet from the ground. The blades of the windmill are 5 feet long. The blade makes one revolution in ___ seconds.

### Explanation:

The question about the rotation of windmill blades is a mathematical problem regarding circular motion, specifically calculating the revolution time for one complete turn of the blades. Since the length of the blade and the height of the axis are provided as constants, these details do not directly affect the time it takes for a blade to complete one revolution. Without additional information, such as the speed at which the blades are turning, we cannot determine the correct answer from the options given.

To solve this type of problem, one would typically need to know either the angular velocity of the blades or have another piece of information that relates to the speed of the rotation. In this case, we have no such information, and therefore it is not possible to provide a definitive answer to the question about the number of seconds it takes for one revolution from the options provided.

The blades of the windmill turn on an axis that is 20 feet from the ground. The blades of the windmill are 5 feet long. The blade makes one revolution in ___ seconds.a) 5

b) 10

c) 15

d) 20 The question related to the time it takes for windmill blades to make one revolution is a mathematics problem in circular motion, but it lacks sufficient details to determine the exact answer. The provided blade and axis measurements do not influence the required time without knowing the angular velocity or another related speed measurement.
