The five steps for determining density can be found in simple form as follows, measure the mass of the container, measure the volume of the liquid(s), measure the combined mass of the liquid and the container, and then determine the mass of the liquid alone and divide the mass by the volume of it.
Answer:
The image distance is 17.56 cm
Explanation:
We have,
Height of light bulb is 3 cm.
The light bulb is placed at a distance of 50 cm. It means object distance is, u =-50 cm
Focal length of the lens, f = +13 cm
Let v is distance between image and the lens. Using lens formula :
![\dfrac{1}{f}=\dfrac{1}{v}-\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{f}+\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{13}+\dfrac{1}{(-50)}\\\\v=17.56\ cm](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7Bf%7D%3D%5Cdfrac%7B1%7D%7Bv%7D-%5Cdfrac%7B1%7D%7Bu%7D%5C%5C%5C%5C%5Cdfrac%7B1%7D%7Bv%7D%3D%5Cdfrac%7B1%7D%7Bf%7D%2B%5Cdfrac%7B1%7D%7Bu%7D%5C%5C%5C%5C%5Cdfrac%7B1%7D%7Bv%7D%3D%5Cdfrac%7B1%7D%7B13%7D%2B%5Cdfrac%7B1%7D%7B%28-50%29%7D%5C%5C%5C%5Cv%3D17.56%5C%20cm)
So, the image distance is 17.56 cm.
