Question 2 Any electricity charged object creates an electric field. Walking across carpet in wool socks can create an electric charge. This

observation is evidence for which characteristics of electrical forces?

They generate electricity by contact.

They can be generated by electricity.

OOO

They can exert a force across a distance.

They are moving due to magnetism.

Positrons are spontaneously emitted from the nuclei of

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

12. a body is a particular amount of matter. it can be a solid, liquid or gas. it can be described as existing in a. size and shape. b. motion and force c. time and space. d. location and movement.
