Answer : Option B
Explaination / Solution:
No Explaination.
Q2. Standard electrode potential are measured with the concentrations of all the species involved in a half-cell is
Answer : Option A
Explaination / Solution:
Under standard condition concentration of every species is taken as 1.
Q3. Which article of the Constitution of India specifies that, "it shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers, and wildlife and to have compassion for living creatures."
Answer : Option B
Explaination / Solution:
All the fundamental duties are contained in Art. 51A.
to protect and improve the natural environment including forests, lakes, rivers, and wildlife and to have compassion for living creatures is a fundamental duty listed in constitution of India.
Q4.
Newton’s law of universal gravitation states that the gravitational force of attraction between any two particles of masses m1 and m2 separated by a distance r has the magnitude
Answer : Option D
Explaination / Solution:
According to Newton's law of universal gravitation, the force of attraction between two objects is directly proportional to the product of two masses and inversely proportional to the square of the distance between them
Q5. In a pure, or intrinsic, semiconductor, valence band holes and conduction-band electrons are always present
Answer : Option A
Explaination / Solution:
An intrinsic semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities. In intrinsic semiconductors the number of excited electrons and the number of holes are equal: n = p.
Q6. At producer’s equilibrium when MR=MC, the firm earns only
Answer : Option C
Explaination / Solution:
No Explaination.
Q7. The largest phylum of kingdom animalia is
Answer : Option A
Explaination / Solution:
Arthropoda is the largest phylum of kingdom animalia. It includes all insects, arachnids, myriapods and crustaceans. They are characterized by jointed limbs and cuticles.
Q8. One of the measures of money supply is
Answer : Option D
Explaination / Solution:
No Explaination.
Q9. The Gynoecium of flower having two or more carpel fuse together are called
Answer : Option D
Explaination / Solution:
Gynoecium is the female reproductive part of flower. It consists of single or more than two carpel( pistil). When these carpels are fused together, they are called syncarpous.
Q10. The number of dots around the Lewis symbols for the elements represent
Answer : Option A
Explaination / Solution:
Gilbert N. Lewis is widely known for his use of simple symbolic representations of elements that show valence electrons as dots.
The Lewis electron-dot symbols focus on the electrons in the highest principal energy level in the atom, the valence electrons.
After all, these are the electrons that participate in chemical reactions. Lewis electron-dot symbols work well for the representative elements.
