Part A What is the proper value of L? Express your answer with the appropriate units. L = μA Value Units ?

Part A A parallel-plate capacitor is constructed from two 15 cm x capacitor plates are charged to + 20 nC, then disconnected from the battery. cm electrodes spaced 1.5 mm apart. The How much energy is stored in the capacitor? Express your answer using two significant figures. HẢ ? U = Value Units Submit Request Answer Part B Insulating handles are used to pull the capacitor plates apart until the spacing is 2.8 mm. Now how much energy is stored in the capacitor? Express your answer using two significant figures. HẢ U2 = Value Units Submit Request Answer Part C Energy must be conserved. How do you account for the difference between A and B? O Work was done to pull the plates apart. O The electric field supplied additional energy. O Kinetic energy of the charges was transformed into potential energy O The battery supplied additional energy. Submit Request Answer

A spherical capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has a radius of ra = 12.4 cm, and the outer sphere has a radius of 7b = 14.9 cm. A potential difference of 120 V is applied to the capacitor. Part A What is the capacitance of the capacitor? Use €0 = 8.85×10-12 F/m for the permittivity of free space. ▸ View Available Hint(s) ΕΧΕΙ ΑΣΦ C = c. ? b x x |X| x.10n Submit Previous Answers Request Answer ☑ F
