Question

magnesium situation of a image is minus one upon two if the object is placed at 60 CM in front of concave mirror and the position of image and focal length of mirror also calculate the radius of curvature of mirror...​

Answer 1

Given

• Object distance, u=24cm

• Image distance, v=16cm

From mirror formula

• f1=v1+u1

• f1=−161−241

• =−(16×2424+16)

• −2410

• f=9.6cm= focal length

Answer 2

Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation [1-3]. Magnesium is required for energy production, oxidative phosphorylation, and glycolysis.
