Consider a modified Bernoulli equation.
$$ \left(\mathrm{P}+\frac{A}{B t^2}\right)+\rho g(h+B t)+\frac{1}{2} \rho V^2=\text { constant } $$
If $t$ has the dimension of time then the dimensions of $A$ and $B$ are $\_\_\_\_$ , $\_\_\_\_$ respectively.
A quantity Q is formulated as $X^{-2}Y^{+\frac{3}{2}}Z^{-\frac{2}{5}}$. X, Y, and Z are independent parameters which have fractional errors of 0.1, 0.2, and 0.5, respectively in measurement. The maximum fractional error of Q is
The dimension of $ \sqrt{\frac{\mu_0}{\epsilon_0}} $ is equal to that of:
($ \mu_0 $ = Vacuum permeability and $ \epsilon_0 $ = Vacuum permittivity)
