WebNov 7, 2024 · The correct answer is Angle. The powers to which fundamental quantities must be raised in order to express the given physical quantity are called its dimensions. A quantity without dimension will usually be a ratio of two quantities with similar dimensions and hence, will cancel out. Thus, they will have no units. WebSep 18, 2024 · Though it can be "dimensionless" like an angle, which is the ratio of two lengths if measured in radians. Of course you can also decide to introduce a new unit like the degree (right angle ##90^{\circ}##).

WebThe results of twist angle is indeed dimensionless, but so are radians! The radian is defined as the ratio of arc length to radius length, so both arc length and radius length have the same unit, then they cancel each other. It's common for many dimensionless quantities in engineering and physics to use radians. You'll get used to it. WebThis ratio is dimensionless since the units of measurement cancel.
