ANS:B - No

No answer description is available. Let's discuss.

ANS:A - cumulative, + 0.11 m

Slope correction = h^2/2L = 1.8^2/(2*15) = 0.108~0.11.
Slope error is always + ive slope correction is always -ive.
So, Cumulative Error. Now we know that given sloping distance is 15meter and difference in elevation is 1.8 meter.

That means we know the slope i.e. H:V = 15 : 1.8.
but slope gives us value of horizontal distance per unit error. We want error per unit horizontal distance here means 1.8 :15.
That gives us 0.12 which is cumulative of course due to slope. Hence it will be +0.12 cumulative or corrected for +0.11 cumulative. By Pythagoras Theorem, the ground distance is 15.10 and slope distance is 15m.

Since Error = Measured value - True Value, and here Measured value is lesser that is 15m, we get the error as -ve.

Hence correction +ve. Therefore, I agree with Option (A) In this question, they are asking for error not correction so.

Correction is always negative.

But the error is positive.
That' s why the answer is +11.

As it is a systematic error not random error so it can be called cumulative error.

ANS:C - Strain gauge

In strain gauge change in resistance occurs.

ANS:B - Kurzweil Data Entry Machine (KDEM)

Kurzweil Data Entry Machine is itself a OCR, to make our answer more specific device, so we choose KDEM.

ANS:C - when there is no motion of one fluid layer relative to an adjacent layer.

The statement "The pressure intensity is the same in all directions at a point in a fluid" refers to a condition known as hydrostatic equilibrium, which occurs when the fluid is at rest and there are no shearing forces or accelerations present. Out of the options provided, the correct condition under which the pressure intensity is the same in all directions at a point in a fluid is: when the fluid is at rest having zero velocity. Here's why this is the correct condition:

• Hydrostatic Pressure: When a fluid is at rest and not in motion (zero velocity), the pressure exerted by the fluid at any point is isotropic, meaning it is the same in all directions. This is because in a static fluid, the pressure is solely determined by the weight of the fluid above the point of interest (hydrostatic pressure).
• Frictionless Fluid (Option 1): A fluid being frictionless does not necessarily imply uniform pressure in all directions. Frictionlessness refers to the absence of viscous forces, not to the distribution of pressure.
• No Motion Relative to Adjacent Layers (Option 3): This condition typically refers to laminar flow rather than static fluid conditions. In laminar flow, adjacent layers move at different velocities, affecting pressure distributions differently than in a static fluid.
• Regardless of Motion Relative to Adjacent Layers (Option 4): This statement is ambiguous and doesn't specify a condition related to pressure uniformity at a point in a fluid.

ANS:B - Arunachal Pradesh

The Central government has planned to collaborate with the Arunachal Pradesh government to develop a 'district good governance portal'.

ANS:C - Bhopal

Madhya Pradesh Chief Minister Mohan Yadav inaugurated the intra-State air service 'PM Shri Paryatan Vayu Seva' from Raja Bhoj International Airport in Bhopal on June 13. This service, operated by Madhya Pradesh Tourism Board (MPTB) in partnership with Jet Serve Aviation Private Limited, aims to boost tourism by connecting eight cities within the state. The initiative includes flights to destinations such as Jabalpur, Gwalior, Indore, and Khajuraho, with plans to expand based on public response, using twin-engine aircraft initially designed to accommodate six passengers each.

ANS:A - Rajasthan

Rajasthan Chief Minister Ashok Gehlot inaugurated the Rajiv Gandhi Centre of Advance Technology (R-CAT).

ANS:B - Maharashtra

Maharashtra government will take a loan of 4,000 crore rupees from the Asian Development Bank (ADB) for setting up medical colleges in 12 districts of the state.
