2.using simple machine properly with right way and precautions
Explanation:
3.cuz if they are not used properly they can cause injuries to organs
A is the answer do ur this question
When object distance is smaller than the focal length of a convex lens, then the rays diverge.
Here, object distance = 20 cm
focal length = 25 cm
20 < 25
Thus, the lens are <u>diverging</u>

<h3>
What is focal length?</h3>
The fundamental description of a camera lens is its focal length, which is often expressed in millimeters (mm). It is not a measurement of the physical length of a lens.
But rather a calculation of the optical distance between the focal plane of the camera's digital sensor or 35mm film to the location where light rays converge to make a sharp image of an object. When a lens is focussed to infinity, its focal length can be calculated.
