See below.

#### Explanation:

$H N {O}_{3} \to {H}^{+} + N {O}_{3}^{-}$

$H F$ $r i g h t \le f t h a r p \infty n s$ ${H}^{+}$ + ${F}^{-}$

According to Arrhenius concept of acids and bases an acid ionizes in water to give ${H}^{+}$ ions in the solution because acids are characterized by the presence of ${H}^{+}$ ions.

According to above reactions, both $H N {O}_{3}$ (completely) and $H F$ (only partially) ionize in water giving ${H}^{+}$ ions. So both are Arrhenius acids.
