Question

13. At what distance from a concave mirror of focal length 10 cm should an object 2 cm long be
to get an erect image 6 cm tall ?
​

Answer 1

Answer:

Advances in physics often enable advances in new technologies. For example, advances in the understanding of electromagnetism, solid-state physics, and nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons;[6] advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus
