level line is a curved line while hori-zontal line is a straight line

level line is normal to plumb line while horizontal line may not be normal to plumb line at thetangent point to level line

horizontal line is normal to plumb line while level line may not be normal to the plumb line

both are same

increasing the diameter of the tube

decreasing the length of bubble

increasing the viscosity of liquid

decreasing the radius of curvature of tube

decreases

increases

remains unaffected

none of the above

completely eliminates curvature correction

partially eliminates curvature correction

adds to the curvature correction

has no effect on curvature correction
