Answers
Answer:The capacitance is cut in half.Explanation:The capacitance of a plate capacitor is directly proportional to the area A of the plates and inversely proportional to the distance between the plates d. So if the distance was doubled we should expect that the capacitance would be cut in half. That can be verified by the following equation that is used to compute the capacitance in such cases:C = (\epsilon)*(A/d)Where \epsilon is a constant that represents the characteristics for the insulator between the plates. A is the area of the plates and d is the distance between them. When we double d we have a new capacitance, given by:C_new = (\epsilon)*(A/2d)C_new = (1/2)*[(\epsilon)*(A/d)]Since C = (\epsilon)*(A/d)] we have:C_new = (1/2)*C

Jordyn I started hanging out with Mariah the summer before our senior year. We both worked as counselors at the same camp, though that seemed to be all we had in common in the beginning. I was into softball, roller derby, and basketball. She read more than my mother—which is saying a lot—and wrote short stories about a sarcastic dragon, which seemed a little crazy to me if I’m being honest. Our friend groups rarely intersected, and most of our friends were not the least bit interested in changin
