20 kg*m/s because there is 2 kg mass and 10 m/s so you can multiply.

The answer to your question is B. When light hits something relatively flat, smooth and shiny, it is reflected by the surface, allowing nearby objects to be seen on the surface.
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.
