ANS:A - over

No answer description is available. 

ANS:A - Yes

A structure pointing to itself is called self-referential structures.

ANS:C - 45 m

Solution;

Note: Here in Q it is not 1 1/2 actually it is only 1/2 so,
if upward slope asked then i.e +ve.
Sight= (Staff ht + instrument ht.)/(Slope)
Sight=(4+1/2)(1/10)
Sight=(4.5)*(10)
Sight=45 m.

And It will be 55 m in case if 1 1/2 only. Slope = 1/10,
H.I = 1/2 = 0.5,
Sight = (0.5 + 4)/1 ÷ 10 = 45.

ANS:D - 100 V, 0.1 mA

Since the current drawn is minimum, the accuracy is maximum.

ANS:C - Direct access

We can access the data only in two ways that is randomly& in sequence mode.

So, the right answer is random.

ANS:A - area of surface in contact.

In laminar flow, the frictional resistance (also known as viscous drag) depends on several factors, but one factor it does not depend on is the pressure of flow. Here’s an explanation of each factor:

1. Area of surface in contact: The frictional resistance in laminar flow depends on the area of the surface in contact with the fluid. A larger contact area generally results in higher viscous drag.
2. Flow velocity: The frictional resistance is directly proportional to the flow velocity. Higher velocities lead to greater shear stresses and therefore higher viscous drag.
3. Fluid temperature: Viscosity of fluids typically changes with temperature, affecting the frictional resistance. However, in the context of laminar flow, the temperature primarily influences viscosity, which in turn affects frictional resistance.
4. Pressure of flow: The pressure of the flow does not directly affect the frictional resistance in laminar flow. While pressure influences the fluid density and may indirectly affect viscosity through temperature changes, it does not alter the frictional resistance in a straightforward manner.

ANS:A - Arunachal Pradesh

The state government of Arunachal Pradesh has given the name 'Donyi Polo Airport' to its third airport, which is under construction in Itanagar.

ANS:C - Chambal River

The Chambal River in Uttar Pradesh harbours over 2000 Gangetic dolphins, as reported by the Wildlife Institute of India. This highlights the importance of the Chambal River in the conservation efforts aimed at protecting these endangered dolphins.

ANS:D - Uttar Pradesh

The Uttar Pradesh government has signed a Memorandum of Understanding with Deloitte India, appointing it as a consultant for achieving the target of raising the state's economy to USD 1 trillion.

ANS:A - Bihar

Bihar is now included in the UNESCO list of Important Endangered Heritage observatories of the world.
