Question

State any two limitations of dimensional analysis. Write the order of magnitude of

66840 km and significant figures in most probable length 17.68 cm.​

Answer 1

Answer:

The method cannot be considered to derive composite relations. Examples s = ut + 1/2 at2 and 2as = v2 – u2. A formula containing trigonometric function, exponential function, and logarithmic function can not derive from it. The method cannot be used to derive the relationship between more than three quantities.
