Question

write that advantage and disadvantage of dimensional analysis​

Answer 1

Advantage is ist and then

Answer 2

Explanation:

Disadvantages of Dimensional Analysis:

• We can get no information about dimensionless constant in the formula.
• If quantity is depend upon more than 3 factors which have dimensions then the formula can not be derived.
• We can not derive formulae which contain trigonometric functions, exponential functions,log functions and many more..which have no dimensions.
• It doesn't give us the clear/proper information/idea about the significance and use of that particular physical quantity.
• We can not derive formulae which contain trigonometric functions, exponential functions,log functions and many more..which have no dimensions.
• It doesn't give us the clear/proper information/idea about the significance and use of that particular physical quantity.It doesn't show us whether the quantity is vector or scalar.

Advantages of Dimension Analysis:

• It helps us to derive formulae.
• It helps us to check whether the formula is correct or incorrect.
• It helps us in the conversion of one system of unit in another system... e.g. metre(m) in centimeter(cm)

These are some advantages and disadvantages of Dimensional Analysis...

These must be more advantages... But I mentioned few of them...

Hope this is sufficient to satisfy you.......
