Q-3) Epigraphy is the study of which of the following ?
(a)
(b)
(c)
(d)
Epigraphy is the study of inscriptions or epigraphs as writing. It is the science of identifying graphemes, clarifying their meanings, classifying their uses according to dates and cultural contexts, and drawing conclusions about the writing and the writers. A per-son using the methods of epigraphy is called an epigrapher or epigraphist.
Q-4) Who discovered electromagnetic nature of light ?
(a)
(b)
(c)
(d)
A theory of electromagnetism was developed by various physicists over the course of the 19th century, culminating in the work of James Clerk Maxwell, who unified the preceding developments into a single theory and discovered the electromagnetic nature of light. In classical electromagnetism, the electromagnetic field obeys a set of equations known as Maxwell’s equations.
Q-5) What is the name given to the outermost “planetoid” discovered recently in the Solar System ?
(a)
(b)
(c)
(d)
Astronomers have discovered a new planetoid at the far edge of our Solar System. The new object, named Sedna, is probably almost as big as the smallest planet, Pluto.
Sedna is very, very far away. It is more than twice as far from the Sun as Pluto, and about 90 times as far from the Sun as Earth. Sedna is probably a huge ball of ice.
The ice is reddish in colour. There are probably chemicals in the ice that make it red. Sedna orbits the Sun once every 10,500 years. Its orbit takes it out to about 900 times as far from the Sun as the Earth.
Q-6) Preservation of historical articles is done in science of
(a)
(b)
(c)
(d)
Museology is the study of museums and museum curation. Because the framework of museums lies in material objects as primary sources, it is indirectly concerned with the preservation of historical articles.

(a)
(b)
(c)
(d)
Q-8) Which company invented the transistor ratio ?
(a)
(b)
(c)
(d)
There are many claimants to the title of the first company to produce practical transistor radios, often it is attributed to Sony (originally Tokyo Telecommunications Engineering Corporation).
A transistor radio is a small portable radio receiver that uses transistor-based circuitry. Following their development in 1954, they became the most popular electronic communication device in history, with billions manufactured during the 1960s and 1970s.
Their pocket size sparked a change in popular music listening habits, allowing people to listen to music anywhere they went.
Q-9) X–rays were discovered by
(a)
(b)
(c)
(d)
X-radiation (composed of X-rays) is a form of electromagnetic radiation.
X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 100 eV to 100 keV. They are shorter in wavelength than UV rays and longer than gamma rays.
In many languages, X-radiation is called Röntgen radiation, after Wilhelm Röntgen, who is usually credited as its discoverer, and who had named it X-radiation to signify an unknown type of radiation.
Q-10) Which one of the following scientists has carried out researches both in the field of Biology and Physics?
(a)
(b)
(c)
(d)
