7. what determines whether a charged object gains or loses electrons?

8. which is more likely to generate static electricity—rubbing teflon and styrene or rubbing styrene and rabbit fur? explain.

9. under what environmental conditions are you most likely to generate static electricity?

10. how is the charge on a charged object maintained?

11. how is a static charge dissipated?

Hello there.

11. Static charge is dissipated through static electricity.

7. The charged object can have two polarities, positive or negative which is determined by the configuration of electron orbitals of the material. If there are free orbitals, it will likely gain electrons and produce a negative charge. If there are free electrons on the outermost orbitals, these electrons will be lost and the material will have a positive charge.

8. Rubbing styrene and rabbit fur because rabbit fur has free orbitals which can hold electrons making styrene positive.

9. When it is dry and windy.

10. When there no other materials that can take or add electrons from or to it.

11. Static charge is dissipated through static electricity.

Explanation:

Displacement is a vector quantity. it is the distance covered in a specific direction.

Whereas, Velocity = displacement/time

Make displacement the subject of formula

Displacement = velocity × time

From the graph, velocity is constant which is equal to 1 m/s

Displacement in the last two seconds will be velocity multiply by 2. Since time = 2s. Therefore,

Displacement = 1 × 2 = 2 m

So, the particle displacement in the last two seconds will be 2 metres
