Japanning is a:
Type of finishing given, usually based on lacquer
Understanding Japanning
The term "Japanning" refers to a specific type of finishing technique. It is a process that gives a hard, glossy finish, often black, to surfaces like wood, metal, and papier-mâché. This finish is typically based on the use of lacquer or varnishes that are heat-dried.
Let's look at the provided options to determine which one accurately describes Japanning:
- Option 1:
Name given to Japanese Information Technology Methods
This option suggests Japanning is related to IT. This is incorrect. Japanning is a historical finishing technique, not related to modern technology methods. - Option 2:
Type of finishing given, usually based on lacquer
This option aligns with the historical definition of Japanning as a finishing process involving lacquer or similar varnishes. This description accurately captures the essence of Japanning. - Option 3:
Kind fishing technology off the coast of Japan
This option relates Japanning to fishing. This is incorrect. Japanning is a method of applying a decorative and protective coating, not a fishing technique. - Option 4:
Kind of Font used to type word documents
This option suggests Japanning is a font style. This is incorrect. Japanning is a physical finishing process applied to objects, not a typographical element.
Based on the analysis of the options and the historical meaning of the term, Japanning is indeed a type of finishing given, usually based on lacquer.

A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
