Question

100points PLzz help me out....Rubbing a glass rod with a silk cloth is an example of charging by

Answer 1

Answer:

When silk is rubbed on a glass rod, an electrostatic charge is generated in a phenomenon known as the triboelectric effect. It is this electric charge that gives you a shock in winter when your rubber-soled shoes rub against a carpeted floor. The triboelectric series is a list of materials sorted according to their electrostatic behavior; using the list, you can predict the electrostatic effects when silk is rubbed on a glass rod.

Explanation:

Answer 2

1. Rubbing a glass rod with a silk cloth is an example of charging by  

     friction

2. Rubbing a glass rod with a silk cloth will cause the rod to become more ____charged because it is losing electrons and the cloth to become more ____ charged because it is gaining electrons.  

      positively ; negatively

3.  All matter is made up of both positive and negative charges, but we can only transfer the ___ charges.

          negative

4. Charging by ______is a method used to charge an object without actually touching the object to any other charged object.  

        induction

5. When a charged object is brought near (without touching) a neutral object, this induces the electrons within the neutral object to move. This is an example of a temporary charge by _____.

      induction  

6.  Grounding allows charged objects to become neutral by electrons either flowing from the earth to the object or electrons flowing from the object to the earth through a conductor.

        True

7.  When an uncharged student (standing on an insulating mat) touches a negatively charged Van de Graaff generator, this is an example of charging by ______.

      conduction

8.   A positively charged object will be repelled by a negatively charged object because the charges are different.

        False

9.  Which of the following is an example of static electricity?

     A build up of charges on a sock from a dryer

10.  According to the image below, the like charges within the metal leaves at the bottom in the glass of an electroscope will be ____ by each other and therefore will ____.

      repelled , spread further apart
