Question

plz 7 ,8 ,9th qution ans plz don't spam .....​

Answer 1

Explanation:

ans 7)The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object. It is the distance between two points in the object that are just resolved in the image. ... Thus an optical system cannot form a perfect image of a point

ans 8 ) the basic monetary unit of Bulgaria, equal to 100 stotinki.

(not sure about the answer)

ans 9) One curie (1 Ci) is equal to 3.7 × 1010 radioactive decays per second, which is roughly the amount of decays that occur in 1 gram of radium per second and is 3.7 × 1010 becquerels (Bq). In 1975 the becquerel replaced the curie as the official radiation unit in the International System of Units (SI).

8.What is an LEV system? An LEV system is an engineering control system to reduce exposure to airborne contaminants such as dust, mist, fume, vapour or gas in the workplace. ... More often that not, your LEV system will also have a filter.
