Charges of +2 µc and +3 µc are 4 mm from each other. raina’s group draws four diagrams trying to represent the electrical force between the charges.

True or false: the revolution of the earth creates day and night as it rotates around the sun

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
