ANS:B - 0.04 m inclined downwards

The 1st setting is a two peg test which eliminates error thus giving true difference in level.
We usually divide by two when the instrument is not at mid point so that errors on both BS and FS are eliminated. This is the formula to be used in reciprocal levelling. Here the staff is kept at the centre first so the true difference between the elevations is the actual difference between them. True level difference get when the level set midway between A & B.

True level difference=1.22-1.06=.16 downward (Greater value give lower elevation so A is lower elevation than B).

And when an instrument set near to a point collimation error eliminate.So we get true reading for A.
True reading at A=1.55.
When instrument set near A then true reading at B=1.55-.16=1.39.
Error=1.37-1.39=-.02.
Error for 50 m=-0.02.
Error for 100 m=2*(-.02)=-0.04. Here when you put level at centre all errors are eliminated .

Hence difference in RL is 1.22 - 1.06 is 0.16 but the observed staff difference is 1.55 - 1.37 = 0.180.

Therefore the error is 0.180 - 0.160 = 0.02 for 50 m, for 100m it is 0.04. It is positive value hence line of sight is upwards. Distance between a and b = 50 m.
When instrument at center=1.22 - 1.06 = .160.
When instrument near A = 1.55-1.37 = .180.
DIFF = .160-.180 = -.020(- INDICATE DOWNWARDS).

COLLIMATION ERROR FOR 100M length = (.020/50)*100 = .04m inclined downward.

ANS:B - pressure

In fluid mechanics, when the velocity head (kinetic energy per unit weight of fluid due to its velocity) is converted into another form of energy in a sudden enlargement of a horizontal pipe, it is typically converted into pressure head. Here’s why:

• Velocity Head: Velocity head (V22g\frac{V^2}{2g}2gV2​) represents the kinetic energy per unit weight of fluid due to its velocity (VVV).
• Sudden Enlargement: In a sudden enlargement of a horizontal pipe, such as an abrupt increase in cross-sectional area, the fluid velocity decreases due to the conservation of mass (continuity equation). As the velocity decreases, the kinetic energy associated with the fluid's motion (velocity head) decreases.
• Conversion into Pressure Head: The decrease in velocity (and hence velocity head) in the sudden enlargement results in an increase in pressure in the pipe. This increase in pressure head represents the conversion of the kinetic energy (velocity head) into potential energy in the form of increased pressure.

ANS:A - Uttar Pradesh

The UP govt plans to double farmers' income under 'Panchamrut Yojana' through the introduction of cost-effective technical measures and promotion of the co-cropping method.

ANS:B - Bangladesh

The inauguration of a new plant near Dhaka by an Indian Pharma giant, Sun Pharma, underscores Bangladesh's growing significance in the pharmaceutical industry. With an annual production capacity of over 1 billion, this development highlights the expanding collaboration between India and Bangladesh in the pharmaceutical sector, showcasing Bangladesh's emergence as a key destination for generic drug manufacturing and India's contribution to meeting its API demand.

ANS:B - Andhra Pradesh

Andhra Pradesh comes out on top (Agri Infra Fund) by placing a strong emphasis on infrastructure development at the farm gate, it has become the best state

ANS:A - Bay of Bengal

Cyclone Remal is forecasted to originate from the Bay of Bengal, intensifying into a severe cyclonic storm before reaching the Bangladesh and West Bengal coasts. This low-pressure system over the Bay of Bengal is expected to develop into Cyclone Remal, posing potential threats to coastal regions with heavy rainfall and strong winds.
