A concave lens has a focal length of -31 {cm}. Find the image distance and magnification that results when an object is placed 29 {cm} in front of the lens. d1= ? cm
m= ?

The value is

and  

Explanation:

From the question we  are told that

    The image  distance is  

    The focal length is

From the lens equation we have that

=>    

=>    

Generally the magnification  is  

=>    

=>    

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

it is the second option.
