A student wants to use the equation for Coulomb's Law to calculate the electric force between two charges. Which shows all of the information she will need to perform the calculation?
F = k 9192 +2
(1 point)
Coulomb's constant, both charges measured in Coulombs
Coulomb's constant, the distance between the charges
both charges measured in Coulombs, the distance between the charges
Coulomb's constant, both charges measured in Coulombs, and the distance between the charges
Coulomb's constant, both charges measured in Coulombs, and the distance between the charges
How does the structure of atoms in a substance determine the substance's conductivity? (1 point)
If an atom's nucleus is O positively charged, the substance is a good conductor.
If an atom's outer shell of electrons is loosely bound to the nucleus, the substance is a good conductor.
If an atom's outer shell of electrons is tightly bound to the nucleus, the substance is a good conductor.
If an atom's outer shell of electrons is positively charged, the substance is a good conductor.
If an atom's outer shell of electrons is loosely bound to the nucleus, the substance is a good conductor.
The student will need the following information to perform the calculation using Coulomb's Law:
- Coulomb's constant
- Both charges measured in Coulombs
- The distance between the charges
Therefore, the correct answer is:
Coulomb's constant, both charges measured in Coulombs, and the distance between the charges.
