Walking across a carpet is an example of charge being transferred by
a. contact.
b. induction.
c. static electricity.
d. friction.

Walking across a carpet is an example of charge being transferred by friction. The answer is letter D. The carpet, which is at rest, will resist the motion cause by your walking. This resistive motion d the friction the carpet obtained from you and you from the carpet.

Answer : The correct answer is- D)  Friction.

There are three modes of charging, which are Conduction, induction, and friction.

The static electricity is produced due to the rubbing of one substance with another. This is called charing by friction.

Hence, the correct answer is friction as there is friction between carpet and the feet of person walking over it.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
