Answer:
Ion-dipole forces
Explanation:
Na⁺ is a cation, that is, an ion with a positive charge.
NH₃ has polar covalent bonds (due to the difference in electronegativity between nitrogen and hydrogen). According to the VESPR theory, it has a trigonal pyramidal shape with a lone pair. As a consequence, it has a net dipole moment and the molecule is polar.
The intermolecular forces between Na⁺ (ion) and NH₃ (dipole) are ion-dipole forces.

Answer:
Composite volcano
Explanation:
Composite volcanoes are also known as stratovolcanoes. They are characterized by their steep sides and symmetrical features. These types of volcanoes are built slowly from the alternating layers of lava flow, ash and cinders erupting from the conduit system, which accumulate and add to the slopes of the volcano.
