Which of the quantity is dimensionless?
Force
Area
Angle
Work
Angle = length of Arc/ radius = L/L = 1 = [M0 L0 T0]
Why work is scalar quantity ? In formula it uses force which is vector quantity and displacement which is a part of vector quantity, then why work is scalar quantity ?
In which is thermionic work function measured? How is it related is it related to the S.I. unit of this quantity?
What is the quantity which is measured by the area occupied below the velocity-time graph?
