Answer 2

IDk.. I'm sorry...

Don't worry thanks :D

Answer 4

They are both contact forces. Action-at-a-distance forces would be, for example, gravity or electrostatic repulsion (though in more advanced physics action-at-a-distance is usually a distasteful idea and is replaced by the idea of a field that acts locally everywhere in space).
