A capacitor is made by sandwiching two thin sheets of aluminum between two layers of neoprene rubber and then rolled into a cylinder. Each of the sheets are 50 cm wide and 50 m long. The layers of rubber are 0.5 mm thick and have a dielectric constant of 6.7. (a) What is the permittivity of neoprene? (b) What is the capacitance of the capacitor? (c) If 12 volts are applied across the capacitor, what is the electric field between the sheets? (d) What is the charge density on the surface of the aluminum sheets? (e) How much energy is stored in the capacitor? olution: the sheets were kept flat instead of being rolled up, we would have a flat-plat ® Java Update Available x de of

The diagram below is comprised of four vectors A, B. C and D. Using addition and subtraction of vectors, describe the following: D A B Note: your answer should be an algebraic expression comprising of A, B. C and D. Make sure to take note of the positions of the tails and heads of each vector. B = 0 = |(i.e., when you add the vectors together, they cancel and equal 0)
