Solve the all parts of following question:
Question: A 25 cm tall object is placed in front of a concave mirror with a radius of 28 cm. The distance of the object to the mirror is 94 cm.
Part I: Calculate the focal length of the mirror.
Part II: Calculate the image distance.
Part III: Calculate the magnification of the image (Remember, a negative magnification corresponds to an inverted image).
Part IV: Calculate the magnitude of the image height.
Please show each step in detail for help.
