These are electrically positive objects.
repel
I think what happens is when it get more protons(+) than electrons(-) or vise versa. This can happen through simple things like when you rub your feet on the carpet and when you touch something metal you get a nice shock, also know as static electricity. What happens here is when the two objects are rubbed together electrons jump between the objects. This is just a small example of how this happens. Hope that helped, Kalrag
Friction strips electrons so the rubbed amber would take on a negative charge. Actually, friction causes charges to shift. Charges are indeed stripped from something, but they are collected up by something else. Amber does, indeed, become negatively charged by rubbing it with, say, fur. The phenomon is called triboelectric effect. And a link is provided.
positive
By electrons
electrons are transferred from glass to rubber
When two objects rubbed together become charged due to electrons being transferred from one object to another.charging by friction is when two different materials are rubbed together or come in contact
when 2 bodies are rubbed together,electrons are transferred this causes static electricity.
The outer surfaces of all substances encountered in our daily lives are covered in electrons. When two surfaces are rubbed against each other, electrons may be transferred from one surface to the other, creating a static charge on each of the substances, one positive and the other negative.

Yes , if elctron goes from fur to rod, fur is positively charged
objects can be negatively charged when it is rubbed with another object; a woolen cloth for example. this is because the electrons from the woolen cloth will be transferred to the object which is being rubbed! only electrons can be transferred to the object and make the object becomes negatively charged.
Because electrons will be transferred from the cloth to the insulating rod. But the charge will be negative.
electrons get transferred in form of energy when photon of energy higher than binding energy falls on it electron is ejected in form of energy by conduction,convection ,radiation
