Acircular plate is heated and expands. if the radius of the plate increases from 12 centimeters to 12.1 centimeters, use differentials to approximate the increase in the area of the top surface. then, find the net change in the area by computing the initial and final area. find the error in your approximation.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
