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. R<span>ubbing 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.

According to the statement there is a force of repulsion between the two objects. Remember that two objects must have the same charge so that they repel each other. In this way if the tape is repelled by a plastic pen that is negatively charged, this allows us to appreciate that the tape is also negatively charged. Now if the tape repels the sphere, therefore the sphere is also negatively charged.
Under these considerations the correct answers would be
2. Sodium ions from the salt water on your hand moved onto the sphere
4. The excess negative charge from the sphere spread out all over your body
6. Electrons from the sphere moved into the salt water on your skin, where they reacted with sodium ions
7. After you touched it, the metal sphere was very nearly neutral.
Answer:
brightness that we observe from a star is related to the energy produced and the distance to the Earth
Explanation:
In stars, the color that we observe is directly related to the temperature of the star by the y of the Wien displacement.
λ_{max} T = 2,898 10³
the brightness that we observe from a star is related to the energy produced and the distance to the Earth
Answer: set up a reminder so you won't forget also try clearing your schedule so you can have more time
