How does increasing the distance between charged objects affect the electric force between them?The electric force decreases because the distance has an indirect relationship to the force. Two balls are placed near one another and hang down, as shown below. Which conclusion is supported by this evidence?Neither ball has a charge. As Chelsea removes her clothes from the dryer, she sees sparks, which are examples of .static discharge

1) An ac source of period T and maximum voltage V is connected to a single unknown ideal element that is either a resistor, and inductor, or a capacitor. At time t = 0 the voltage is zero. At time t = T/4 the current in the unknown element is equal to zero, and at time t = T/2 the current is I = -Imax, where Imax is the current amplitude. What is the unknown element? A) a resistor B) an inductor C) a capacitor D) an inductor or a capacitor Answer: C 2) When an LRC series circuit is driven at...
