Calculate the focal length of the mirror formed by the convex side of a shiny spoon that has a 2.23 cm radius of curvature.

1.115cm

Explanation:

For a given mirror (concave or convex), the focal length (f) is related to its radius of curvature (R) by the following;

f =             ----------------(i)

Now, from the question;

R = 2.23cm

To get the focal length, substitute the value of R = 2.23cm into equation (i) as follows;

f =

f = 1.115cm

Therefore, the focal length of the mirror is 1.115cm

This is what i found “in a gas turbine engine, the combustor or combustion chamber is fed high pressure air by the compression system. early gas turbine engines used a single chamber known as a can type combustor. today three main configurations exist: can, annular and cannular (also referred to as can-annular tubo-annular).” i hope this you for what your looking for. can you plz mark me brainliest?
