ANS:B - Either III only, or I and II together

I and II give, profit after 3 years = Rs.		3	x 22000		= Rs. 8250.
		8

P's share = Rs.		8250 x	5		= Rs. 3750.

ANS:A - inevident

No answer description is available. 

ANS:B - False

False, the preprocessor cannot trap the errors, it only replaces the macro with the given expression. But the compiler will detect errors.

ANS:E - All the above,

The correct answer is Option E.

Reason:
Absence of sunlight indirectly means the absence of air,
Absence of air causes dampness,
Dampness = sap.
Stagnant air means no air movement in other words improper ventilation.

ANS:B - 60

If speed is 60, the counter will count 60 x 60 = 3600 counts/per minute.

ANS:B - crystallisation

Crystallization is a separation and purification process used to produce solid crystals from a solution, melt, or gas. It is widely employed in various industries, including pharmaceuticals, chemicals, food processing, and materials science, to obtain pure substances or to recover valuable products from solutions. Here's how crystallization typically works:

1. Solution Preparation: Crystallization begins with the preparation of a solution containing the substance to be crystallized (the solute) dissolved in a suitable solvent. The solute may be dissolved in the solvent by heating or agitation until a clear solution is formed.
2. Saturation: The solution is then cooled or evaporated under controlled conditions to reach a state of supersaturation. Supersaturation occurs when the solution contains more dissolved solute than it would be able to dissolve under normal conditions. At this point, the solution is unstable, and the excess solute tends to precipitate out of the solution in the form of crystals.
3. Nucleation: Once the solution becomes supersaturated, nucleation occurs, where individual solute molecules or ions come together to form small clusters or nuclei. Nucleation can be spontaneous or induced by seeding the solution with tiny crystals of the solute or by agitation.
4. Crystal Growth: The nuclei act as sites for further crystal growth. As more solute molecules or ions are deposited onto the nuclei, the crystals grow in size. The growth of crystals occurs by the addition of solute molecules or ions from the surrounding solution onto the crystal surfaces.
5. Separation: Once the desired crystal size is achieved, the crystals are separated from the remaining solution. This can be done by filtration, centrifugation, or other solid-liquid separation techniques. The separated crystals are then washed with a solvent to remove impurities adhering to their surfaces.
6. Drying: Finally, the purified crystals are dried to remove any remaining solvent. This can be done by air drying, vacuum drying, or by heating in an oven.

ANS:C - depends on the weight of the floating body.

Buoyant force acts vertically upward on a floating or submerged body and is primarily determined by the displaced volume of fluid, which is equal to the weight of the fluid displaced (Archimedes' principle). Let's evaluate each statement:

1. Buoyant force for non-symmetrical bodies is not vertical:
   • This statement is incorrect. Buoyant force always acts vertically upward, regardless of the shape or symmetry of the body. It is a result of the pressure difference between the top and bottom surfaces of the immersed body, causing a net upward force.
2. Buoyant force depends on the depth of the submergence of the floating body:
   • The depth of submergence affects the volume of fluid displaced by the body. However, the buoyant force depends solely on the volume of fluid displaced (Archimedes' principle) and not directly on the depth of submergence.
3. Buoyant force depends on the weight of the floating body:
   • This statement is also incorrect. The buoyant force is determined by the volume of fluid displaced (equal to the volume of the submerged part of the body) and the density of the fluid in which it is immersed, not on the weight of the body itself.

Conclusion:

• Acts vertically upward.
• Depends on the volume of fluid displaced (which is equal to the weight of the displaced fluid).
• Is independent of the depth of submergence or the weight of the floating body itself.
