Step 1: In the value 0.0500L, the zeros following the decimal point but preceding non-zero digits are not counted as significant.
Step 2: The two zeros after the non-zero digits '5' are significant because they are trailing zeros in a decimal portion of the number.
Step 3: Therefore, there are three significant figures (5, 0, 0) in the measurement 0.0500L.
The expression given below shows the variation of velocity \( v \) with time \( t \): \[ v = \frac{At^2 + Bt}{C + t} \] The dimension of \( A \), \( B \), and \( C \) is:
