A converging lens of focal length 8.000 cm is 19.5 cm to the left of a diverging lens of focal length -6.00 cm. A coin is placed 12.1 cm to the left of the converging lens.
(a) Find the location of the coin's final image relative to the diverging lens. (Include the sign of each answer. Enter a negative value if the image is to the left of the diverging lens.)
cm

(b) Find the magnification of the coin's final image.

Explanation:

Firs of all, we calculate the position of the image of the ring with the converging lens. After this we take the image of the ring as the object for the diverging lens (we have to use the lens' equation, and we assume that objects to the left are positive and images to the right are positive).

(a) Hence, we have for the first step

so, the image is at a distance of 23.6 cm to the right of the converging lens. The distance between both converging and diverging lens is 19.5cm. Hence the position of the image of the ring (produced by the first lens) is

23.6cm - 19.5cm = 4.1cm

4.1 cm to the right of the diverging lens. Hence we have for a diverging lens

where we take do=-4.1cm beacuse the object is to the right. The image is to the left of the diverging lens

(b)

The magnification is

this constant is a factor for the second magnification

I hope this is useful for you

regards

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
