Rajashreewants to get an inverted image of height 5cm of an object kept at a distance of 30 cm from a concave mirror. The focal length of the mirror is 10 cm. At what distance from the mirror should she placethe screen? What will be the type of the image and what is the height of the object?

c) conduction

  • The transfer of internal energy of the object by collisions of particles and the movement of electrons within a body is known as thermal conduction.
  • Heat transfer from a hotter to a colder body
  • one of the examples of conduction of heat is when the hotplate of an electric stove to the bottom of a saucepan is in contact with it.
  • The heat flows from one point to another through conduction.
  • The metal surface facilitates the process of conduction.
  • Heat transfer from one end to another; hence, each pinfalls one by one.

The answer to the question is conduction.
