- Question 1 of 7
1. Question
1 pointsCategory: Science and TechnologyConsider the following statement:
- In nuclear reactor, self-sustained chain reaction is possible , because
- More neutrons are released in the each of the fission reaction
- The neutrons immediately take part in the fission process
- The fast neutrons are slowed down by graphite
- Every neutron released in the fission reaction initiates further fission.
Which of these statements is/are correct?
Correct
Statement 2 is not correct. In nuclear chain reaction is controlled. In each fission of U-235 or PI-239 atom, neutrons are produced. In nuclear reactors two neutrons of these three are absorbed with the help of moderators e.g. Graphite, heavy water or Beryllium Oxide . the remaining ‘one’ neutron is used immediately to break one atom of nuclear fuel and the cycle is repeated the neutrons take part in the process , then the reaction will go out of control and the reactors will become an atom bomb.

3. Question
1 pointsCategory: Science and TechnologyDomestic electrical wiring is basically a
Correct
Domestic electric wiring is basically done in parallel connection because electricity can be supplied equally to all the instruments in a house and also when one circuit is broken electric current still flows in other circuits.

4. Question
1 pointsCategory: Science and Technologylow temperature (cryogenics) find application in
Correct
Cryogenic engine is used for rocket propulsion particularly GSLV of space programme and ballistic missiles
Cryosurgery is the branch of surgery which is used to destroy malignant tissue such as cancer cells etc.
‘cryosurgery technology‘ is also used in the production of very high magnetic field and remote sensing.

5. Question
1 pointsCategory: Science and Technologywhich one of the following elements is alloyed with iron to produce steel which can resist high temperature and also have high hardness and abrasion resistance?
Correct
The hardness of steel is proportional to the percentage of chromium present. Chromium is alloyed with iron to produce steel which can resist high temperature and also have high temperature and also have high hardness and abrasion resistance. It is called stainless steel.

6. Question
1 pointsCategory: Science and TechnologyWhich one of the following is not an essential micronutrient for plants?
Correct
Micronutrients or trace elements are essential mineral elements required in small quantities for plant growth and development. They are Fe, Mn, B, Cu, Zn Mo, Ni and CL, Sodium (Na) is required only for halophytes and not for all plants.
