$A$ sample was weighed using two different balances. The results were $(I)$ $3.929 \ g$ and $(II)$ $4.0 \ g$. How would the weight of the sample be reported in $g$?

The candela is the luminous intensity,in a given direction,of a source that emits monochromatic radiation of frequency '$A$' $\times 10^{12}$ hertz and that has a radiant intensity in that direction of $\frac{1}{B}$ watt per steradian. '$A$' and '$B$' are respectively

Evaluate the following exponential numbers:
$(i)$ Add $8.56 \times 10^{6}$ and $10.64 \times 10^{5}$.
$(ii)$ Subtract $5.80 \times 10^{-4}$ from $3.33 \times 10^{-3}$.

Which instruments are used to measure pressure and temperature?

In the equation of state of an ideal gas $PV = nRT$,the value of the universal gas constant $R$ depends only on:
