Answer:
W=0.94J
Explanation:
Electrostatic potential energy is the energy that results from the position of a charge in an electric field. Therefore, the work done to move a charge from point 1 to point 2 will be the change in electrostatic potential energy between point 1 and point 2.
This energy is given by:

So, the work done to move the chargue is:

The work is positive since the potential energy in 1 is greater than 2.
Density<span> = Mass/Volume. The units for </span>density<span> are grams per cubic centimeter or grams per milliliter </span>
Explanation:
a. A grocery bag as you lift it up
b. A crane moving dirt......
d. A crate as you push it along the floor
Ionization energy is the amount of energy necessary to <em>remove an electron from an atom.</em>
If the atom was neutral to begin with, then removing an electron makes it ionized.
