ANS:C - Had the room been brighter

No answer description is available. 

ANS:B - In the first statement 6 specifies a array size, whereas in the second statement it specifies a particular element of array.

The statement 'B' is correct, because int num[6]; specifies the size of array and num[6]=21; designates the particular element(7^th element) of the array.

ANS:E - 1718.9 S/R.

I don't think this answer (E) is correct.
It is only correct if the sub chord, S, was actually the sub arc length. Otherwise, the real answer should be sin^-1 (S/2R)*60. Actually the angular method of curve setting ,by Rankine's deflection method the deflection angle b/w chord and point of tangency is =1720C/R i, where c is the first sub chord and R is the radius. The angle of deflection in radian = S/2R.
The angle of deflection in degree = S/2R × 180/π
The angle of deflection in minutes = S/2R × 180/π × 60.
= 1718.18 ×S/R. For an angle of deflection in MINUTES then use = (S/2R)*(180/π)* 60.
= S/R*((180*60)/(2*(22/7)).
=S/R *1718.18,
=1718.18S/R Angle of deflection= (360/4π)* S/R.
This gives answer 28.64 S/R.
which is in degrees,, soo one degree is 60 min.
Thus, 28.64 S/R degrees in radians is answer E) 1718.9 S/R.

ANS:A - tray

Sticky material can be dried in a fluidized bed dryer. Fluidized bed dryers are particularly suitable for drying sticky materials because of their unique operating principle. In a fluidized bed dryer, hot air is passed through a perforated plate or grid at the bottom of a chamber, causing the solid particles to become suspended or fluidized in the airstream. This creates a fluid-like behavior of the solid particles, allowing for excellent mixing and heat transfer. Sticky materials, which tend to agglomerate or clump together during drying, can be effectively dried in a fluidized bed dryer because the constant movement of the particles prevents them from sticking to each other or to the dryer walls. Additionally, the high turbulence within the fluidized bed promotes rapid evaporation of moisture from the surface of the sticky material, resulting in efficient drying.

ANS:C - represents the conservation of mass.

The continuity equation represents the conservation of mass.

Explanation:

1. Continuity Equation:
   • The continuity equation is a fundamental principle in fluid mechanics that states that the mass flow rate (or volumetric flow rate) of a fluid is constant within a closed system, provided there is no mass added or subtracted from the system: ∂ρ∂t+∇⋅(ρv)=0\frac{\partial \rho}{\partial t} + \nabla \cdot (\rho \mathbf{v}) = 0∂t∂ρ​+∇⋅(ρv)=0 where:
     • ρ\rhoρ is the density of the fluid,
     • v\mathbf{v}v is the velocity vector of the fluid.
   • This equation essentially states that the rate of change of density in a control volume is equal to the negative of the divergence of the mass flux density (density times velocity).
2. Properties of the Continuity Equation:
   • Independence of Compressibility: The continuity equation is valid for both compressible and incompressible fluids. It does not explicitly depend on the compressibility of the fluid.
   • Dependence on Viscosity: While viscosity influences the flow behavior and shear stress distribution within a fluid, it does not directly affect the continuity equation itself. The continuity equation primarily addresses mass conservation.
   • Conservation of Mass: The continuity equation fundamentally represents the principle of conservation of mass, ensuring that the total mass within a control volume remains constant over time (assuming no mass sources or sinks).
3. Conclusion:
   • Therefore, the correct statement regarding the continuity equation is that it represents the conservation of mass. This principle holds true regardless of the compressibility or viscosity of the fluid, making the equation a cornerstone in fluid mechanics and conservation laws.

ANS:A - Rajasthan

The famous Tal Chhapar blackbuck sanctuary in Rajasthan's Churu district has received a protective cover against a proposed move of the State government to reduce the size of its eco-sensitive zone. To protect the sanctuary, the Rajasthan High Court ordered a "complete prohibition" on any action to reduce the wildlife sanctuary's area.

ANS:C - 1975

Regional Rural Banks (RRBs) were established in 1975 by the Indian government to extend banking services to rural areas. The recent allocation of Rs 6212.03 crore by the Modi government aims to reinforce RRBs, highlighting their crucial role in providing financial support to small farmers, artisans, and entrepreneurs in rural India.

ANS:C - DBS Bank

DBS Bank India pledged USD 250 million to support new-age start-ups and 'new economy' companies, demonstrating its commitment to fostering innovation and entrepreneurship in India's start-up ecosystem amid challenges related to capital accessibility.

ANS:A - YES Bank

YES Bank has collaborated with the Indian Olympic Association (IOA) as the Official Banking Partner for Team India at the Paris Olympics 2024, launching the 'Milkar Jitayengey' campaign and introducing the 'YES Glory Debit Card' and 'YES Glory' savings account to support India’s Olympic athletes.
