What is the mnemonic for remembering the instrument formula?

  1. WALA

  2. LAWA

  3. ALAW

  4. AWAL

The correct answer is: WALA

The mnemonic stands for "Weight of instrument, Area of instrument, Length of instrument, and Anchor of instrument". Option B, LAWA, is incorrect because it does not include the "anchor" component. Option C, ALAW, and D, AWAL, are incorrect because they do not follow the correct order of the formula. Remembering the correct order and components through the mnemonic "WALA" can help one easily recall the instrument formula.
