Answer:
Strain and Angle
Explanation:
Tension and surface tension have different dimensional formulas as the tension is measured as force and surface tension is measured as force per unit length.
Year represents time and light year represents distance, thus they also have different dimensions.
Strain is defined as ratio of change in length (or area or volume) to the original length (or area or volume) and so it must be dimensionless.
Angle is nothing but ratio of arc length and radius which is also dimensionless.
Thus strain and angle both have the same dimensions which can be written as [M°L°T°].
