Q2. AIDS can be detected by
Answer : Option B
Explaination / Solution:
A series of blood screenings are performed to test for HIV. The enzyme-linked immunosorbent assay (ELISA), also known as an enzyme immunoassay (EIA), is the first test that your healthcare provider will order to screen for HIV. ELISA, like the Western blot test, detects HIV antibodies in your blood.
Q3. A metal in a compound can be displaced by another metal in the uncombined state. Which metal is a better reducing agent in such a case?
Answer : Option B
Explaination / Solution:
Reducing agent is one in which element undergo oxidation itself and make the other substance reduce.
Q4. Name the fluid from which foetal cells are obtained for chromosomal analysis.
Answer : Option A
Explaination / Solution:
Amniotic fluid is used to obtain foetal cells for chromosomal analysis. This method is misuse as it can determine the sex of foetus. The fluid is collected form the surrounding of growing foetus.
Q5. An example of non durable goods is
Answer : Option B
Explaination / Solution:
No Explaination.
Q6. The sharpness of resonance is given by
Answer : Option B
Explaination / Solution:
Sharpness of resonance is quantitatively described by a dimensionless number known as Q-factor or quality factor which is numerically equal to ratio of resonant frequency to bandwidth.
therefore
Q-factor = resonant frequency / bandwidth
sharpness of resonance =
Q7. Which of the following is true about equipotential lines
Answer : Option B
Explaination / Solution:
The potential at all points on an equipotential surface is constant and work done in moving a charge on an equipotential surface is zero. Electric field lines show the direction of the electric field at the point. If the electric field lines were tangential, parallel or opposite to the equipotential surface, a tangential field will exist on the surface and work done in moving a charge on the surface is not zero. Therefore electric field lines are always perpendicular to the equipotential surface.
Q8. MU1 + MU2 + ……..MUn represents?
Answer : Option B
Explaination / Solution:
No Explaination.
Q9. Substances that are strongly attracted by applied magnetic field and can be permanently magnetized are
Answer : Option D
Explaination / Solution:
Ferromagnetic substance get permanently magnetised in applied Magnetic Field.
Q10. Addition polymers formed by the polymerisation of a single monomeric species
Answer : Option C
Explaination / Solution:
When single monomer is present polymer is homopolymer.
