What is the focal length of a lens if an object placed 3.28 cm from the lens produces an image that is 4.11 cm in front of the lens?

1.82 cm

Explanation:

The relationship between the object distance (p), image distance (q) and focal length (f) is given by

According to question,

Object distance (p) = 3.28 cm

Image distance (q) = 4.11 cm

Therefore,

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.
