3. If the microscopes at school had a low power field of view of 5.2mm, of view be? How big would an object be that took up 1/4 of this field?

Here's how to solve this problem:<br /><br />1. **Understand the problem:** We know the diameter of the low power field of view (FOV) is 5.2 mm. We want to find the size of an object that occupies 1/4 of this field of view.<br /><br />2. **Calculate the size of the object:** Since the object takes up 1/4 of the field of view, we multiply the diameter of the FOV by 1/4:<br /><br /> (1/4) * 5.2 mm = 1.3 mm<br /><br />3. **Answer:** The object would be 1.3 mm in size.<br />
