Physics QUESTION #1189

Question 2530

The Ultraviolet catastrophe means:

The spectral energy concentration towards longer wavelength.
The spectral energy concentration at the middle of the spectrum.
The spectral energy concentration towards shorter wavelength side.✔️
None of these

Correct Answer Logic:

The ultraviolet catastrophe was a prediction of classical physics (Rayleigh-Jeans law) that a blackbody should radiate infinite energy at very short (ultraviolet) wavelengths: $u(\nu) \propto \nu^2 T$. The spectral energy density was predicted to increase without bound towards shorter wavelengths, which was catastrophically wrong and was resolved by Planck's quantum hypothesis.

Civil Engineering QUESTION #2132

Question 2532

In transportation engineering, the California Bearing Ratio (CBR) test is used to:

Measure the compressive strength of subgrade soil for designing airport runways only
Evaluate the bearing capacity of subgrade and sub-base materials relative to a standard crushed stone material — the CBR value is used as input to empirical pavement thickness design methods (IRC, AASHTO) to determine required pavement structure depth✔️
Measure the permeability of road base materials for drainage design
Determine the optimum moisture content of subgrade soils for compaction

Correct Answer Logic:

CBR = (load to cause 2.5mm or 5.0mm penetration in test soil / load for same penetration in standard crushed stone) × 100%. It was developed by California Division of Highways and adopted worldwide for flexible pavement design. High CBR (>80%): excellent subgrade; medium (20–50%): fair; low (<5%): poor, requiring thick pavement. It is used in IRC:37, AASHTO, and most national pavement design guides.

Question 2535

Two trains start at the same time from cities A and B, 300 km apart, moving towards each other. Train A moves at 80 km/h and Train B at 70 km/h. In how many hours will they meet?

2 hours✔️
2.5 hours
3 hours
3.5 hours

Correct Answer Logic:

Relative speed (moving towards each other) $= 80 + 70 = 150$ km/h. Time $= \dfrac{300}{150} = 2$ hours.

Agronomy QUESTION #2090

Question 2536

In organic farming systems, nitrogen fertility is maintained through which suite of mechanisms that must substitute for synthetic N fertilizers?

Urea application at reduced rates combined with biological control
Biological nitrogen fixation (legumes in rotation/intercropping), composted organic matter inputs, green manuring, crop residue recycling, and managed livestock integration — collectively building soil organic N pools and stimulating mineralization✔️
Exclusive use of rock phosphate and potassium sulfate
Deep tillage to expose and mineralize subsoil organic nitrogen reserves

Correct Answer Logic:

Certified organic systems prohibit synthetic N fertilizers. N supply relies on: (1) BNF through legume rotation (60–200 kg N/ha/yr), (2) compost and FYM application, (3) green manuring with leguminous cover crops, (4) crop residue decomposition, and (5) enhanced soil biological activity mineralizing organic N. The challenge is synchronizing N mineralization with crop demand — organic N release is weather and microbially dependent.
