Q1. Utility of a good can be explained as a?
Answer : Option D
Explaination / Solution:
No Explaination.
Q2. Angular momentum is
Answer : Option D
Explaination / Solution:
Axial vector represent rotational effect and are always along the axis of rotation. Direction of angular momentum always along the axis of rotation in accordance with right hand screw rule. Hence angular momentum is an axial vector.
Q3. The molecules on the surface,are-
Answer : Option A
Explaination / Solution:
The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules:A molecule in the bulk liquid experiences cohesive forces with other molecules in all directions.A molecule at the surface of a liquid experiences only net inward cohesive forces.The unbalanced attraction of molecules at the surface of a liquid tends to pull the molecules back into the bulk liquid leaving the minimum number of molecules on the surface. It required energy to increase the surface area of a liquid because a larger surface area contains more molecules in the unbalanced situation and this may results as the surface being stretched.
Q4. Substances that are strongly attracted by applied magnetic field and can be permanently magnetized are
Answer : Option C
Explaination / Solution:
Ferromagnetic substance get permanently magnetised in applied Magnetic Field.
Q5. Select the correct equation from the following
Answer : Option C
Explaination / Solution:
Water potential of a cell is affected by both solute and pressure potential. The relationship between them is as follows:
Q6. The cell lining the blood vessels are
Answer : Option D
Explaination / Solution:
Endothelium is a type of epithelium that lines the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. It is a thin layer of simple squamous called endothelial cells
Q7. We can calculate the change in entropy of a reversible process by
Answer : Option B
Explaination / Solution:
is used to measure entropy system undergoin reversible
Q8. Which archaebacteria is present in the guts of ruminant animals such as cows and buffaloes?
Answer : Option D
Explaination / Solution:
Methanogens are present in the guts of several ruminant animals such as cows and buffaloes and they are responsible for the production of methane (biogas) from the dung of these animals.
Q9. BOP is
Answer : Option D
Explaination / Solution:
Balance of Payments (BOP) records all external transactions on both current as well as the capital account.
Q10. Which transactions determine the balance of trade?
Answer : Option A
Explaination / Solution:
The difference between the value of goods and services exported out of a country and the value of goods and services imported into the country. The balance of trade is the official term for net exports that makes up the balance of payments. The balance of trade can be a "favorable" surplus (exports exceed imports) or an "unfavorable" deficit (imports exceed exports). The official balance of trade is separated into the balance of merchandise trade for tangible goods and the balance of services.
