[Solved] Which of the following has unit but no dimension?

Webdimension of length. A solid angle was de ned as a ratio of an area to the square of a length. As a result of these de nitions of angles, their units also became dimensionless. Since 1995 the unit of plane angle is de ned as the dimensionless number \one", equal to the ratio of a meter to a meter, and the unit of solid angle is also ... WebJust because angles and solid angles are dimensionless doesn’t mean they don’t have units. The natural unit for angle is the radian, defined as the angle subtended at the center of a circle by an arc whose length equals the radius of the circle.
