It is π for an octant, 2 π for a hemisphere, 4 π for a full sphere, − 4 π for a full pseudosphere and so on. Webeg: strain, plane angle Dimensional constants. Physical quantities that have constant values but still have dimensions, are called dimensional constants. eg: Planck’s constant (h), Universal gravitational constant (G) Dimensionless constants. Pure numbers like, 1,2,3, π etc. are called dimensionless (non-dimensional) constants.

Web30 apr. 2024 · You will see reference to the phase (angle) as a dimensionless unit in equations involving complex numbers. – Carl Witthoft Apr 30, 2024 at 13:24 Add a comment 2 Answers Sorted by: 4 +50 I have learnt that the dimensionless quantities have no unit. Whoever you learnt this from is incorrect . WebAngles are not dimensionless. A couple of popular units are degrees and radians. It is possible (though not very common) to represent an angle as a fraction of a whole circle. That would be dimensionless because it is a ratio of angles. There is no analogue for linear distance. Fractions of infinity are just infinity.
Web$\begingroup$ I have discarded (d) because the fact that the angle is constant doesn't mean it has to be maximum. Also, I discarded (b) because the optimal lift coefficient is attained … Web27 apr. 2016 · So, an angle is indeed dimensionless, but fundamentally so are lengths, time intervals, masses temperatures etc. etc. Now, as pointed out in the other answers, …
