The resistance is $10.845 \ \Omega$ and the current is $3.23 \ A$. The voltage is $35.02935 \ V$. Express the result in appropriate significant figures. (in $V$)

Statement-$1$: All reliable digits plus the first uncertain digit together are called significant figures.
Statement-$2$: Trailing zero$(s)$ in a number with a decimal point are never significant.

Which of the following measurements is the most accurate?

Evaluate $\sqrt{6.5 - 6.32}$ considering the rules of significant figures.

For the four sets of three measured physical quantities as given below,which of the following options is correct?
$(i)$ $A_{1}=24.36, B_{1}=0.0724, C_{1}=256.2$
$(ii)$ $A_{2}=24.44, B_{2}=16.082, C_{2}=240.2$
$(iii)$ $A_{3}=25.2, B_{3}=19.2812, C_{3}=236.183$
$(iv)$ $A_{4}=25, B_{4}=236.191, C_{4}=19.5$

The respective number of significant figures for the numbers $23.023$,$0.0003$,and $2.1 \times 10^3$ are:
