ANS:A -

The transit rule is that which is applied when the angular measurement is more accurate than linear measurement. For correction of latitude or departure by transit rule, we can use this formula. 5.
(error in latitude X latitude of that side/ arithmetic sum of all traverses). If the error is dx then it is divided into equal parts.
Then it is dx/Σlat.
But the original latitude is l then correction is given by lx (dx/Σlat).

ANS:D - one voltmeter, one ammeter and one wattmeter

, we need to, measure active power, voltage and current.

ANS:E - None of the above

The control unit is a component of a computer's central processing unit (CPU) that directs operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions.

To find the force required to hold a spherical balloon stationary in water at a depth HHH from the air-water interface, we need to consider the buoyant force acting on the balloon due to the displaced water. Here are the steps to calculate the force:

1. Buoyant Force Calculation:
   • The buoyant force FbF_bFb​ acting on the balloon is equal to the weight of the water displaced by the balloon.
   • The displaced volume of water VdisplacedV_{\text{displaced}}Vdisplaced​ by the balloon is the volume of the spherical balloon submerged in water.
2. Volume of the Balloon:
   • The volume VballoonV_{\text{balloon}}Vballoon​ of a spherical balloon is given by: Vballoon=43πr3V_{\text{balloon}} = \frac{4}{3} \pi r^3Vballoon​=34​πr3 where rrr is the radius of the balloon.
3. Submerged Volume:
   • The volume submerged VsubmergedV_{\text{submerged}}Vsubmerged​ depends on the depth HHH of submersion.
   • For a spherical cap submerged to depth HHH, the submerged volume can be found using geometric formulas, but a simpler approach is to use the volume of the whole sphere and subtract the volume above the depth HHH.
4. Buoyant Force Formula:
   • The buoyant force FbF_bFb​ is given by the weight of the displaced water: Fb=ρwater⋅g⋅VsubmergedF_b = \rho_{\text{water}} \cdot g \cdot V_{\text{submerged}}Fb​=ρwater​⋅g⋅Vsubmerged​ where:
     • ρwater\rho_{\text{water}}ρwater​ is the density of water,
     • ggg is the acceleration due to gravity,
     • VsubmergedV_{\text{submerged}}Vsubmerged​ is the volume of water displaced by the submerged part of the balloon.
5. Density and Gravity Values:
   • Density of water, ρwater=1000\rho_{\text{water}} = 1000ρwater​=1000 kg/m³ (assuming standard conditions).
   • Acceleration due to gravity, g=9.81g = 9.81g=9.81 m/s².
6. Calculations:
   • Radius of the balloon, r=0.1r = 0.1r=0.1 m.
   • Volume of the whole balloon, Vballoon=43π(0.1)3V_{\text{balloon}} = \frac{4}{3} \pi (0.1)^3Vballoon​=34​π(0.1)3 m³.
   • Submerged volume VsubmergedV_{\text{submerged}}Vsubmerged​ can be calculated geometrically or approximated based on HHH.
