Q1. The strength of a reductant/oxidant in redox systems can be determined
Answer : Option C
Explaination / Solution:
Because a redox indicator (also called an oxidation-reduction indicator) is an indicator which undergoes a definite color change at a specific electrode potential.
Q2. Histamine is secreted by
Answer : Option D
Explaination / Solution:
Histamine is responsible for allergic reaction in the body in response to allergens. It is released from mast cell in response to infection or entry of foreign body.
Q3. An example of capital goods is
Answer : Option D
Explaination / Solution:
No Explaination.
Q4. Transformer uses the follwing principle of
Answer : Option C
Explaination / Solution:
A transformer consists of two electrically isolated coils. It works on the principle of mutual induction of two coils or Faraday Law’s Of Electromagnetic induction. When current in the primary coil is changed the flux linked to the secondary coil also changes.hence an EMF is induced in the secondary coil due to Faraday law’s of electromagnetic induction.
Q5. Electrostatic shielding is based
Answer : Option B
Explaination / Solution:
Electric field inside a cavity is always zero. The potential inside a cavity of a conductor is constant. The potential difference between any two points inside a charged conductor is zero. This phenomenon is called electrostatic shielding.
Q6. Solids with conductivities ranging from
Answer : Option B
Explaination / Solution:
They are good conductors of electricity.
Q7. An indifference curve is always?
Answer : Option B
Explaination / Solution:
No Explaination.
Q8. Which of the following is used as for manufacturing conveyor belts, gaskets and hoses.
Answer : Option D
Explaination / Solution:
Neoprene is used in the manufacturing of Conveyor belts and hoses.
Q9. Most metal oxides are
Answer : Option B
Explaination / Solution:
In general, metal oxides are basic and ionic in nature.
Q10. Water potential of pure water and its solution are
Answer : Option B
Explaination / Solution:
The water potential of pure water at standard temperatures, which is not under any pressure, is taken to be zero. If some solute is dissolved in pure water, the solution has fewer free water and the concentration of water decreases, reducing its water potential.
