Question 4 4 pts Which statement concerning the function of a battery is true? O A chemical reaction in the battery provides energy for the moving electrons. The battery pushes protons around the circuit to generate electricity. Charges move because the battery makes them attracted to the resistors. Electric forces in the battery don't have much of an effect on moving charges. Question 5 4 pts Africtional force of 7 N acts on a mass for 21 m as it...
