Which of the following quantities has the dimension [M^0 L^0 T^0]?

Which of the following quantities has the dimension [M^0 L^0 T^0]?

Step 1: Understand what dimensions mean. Dimensions are used to describe physical quantities in terms of mass (M), length (L), and time (T).
Step 2: Recognize that [M^0 L^0 T^0] means there is no mass, no length, and no time involved. This is called a dimensionless quantity.
Step 3: Identify examples of dimensionless quantities. One common example is an angle, which can be measured in degrees or radians.
Step 4: Conclude that since an angle does not depend on mass, length, or time, it is dimensionless and has the dimension [M^0 L^0 T^0].
