Good handwriting plz

2. As part of a science fair project, you want to construct several capacitors with different dielectrics inside. The conducting plates will be made from aluminum (with surface area A). The first capacitor uses a plane of glass with thickness d, surface area 4, and dielectric constant x (Figure 1). It has capacitance Class. The second uses a piece of plastic with thickness d/2, surface area 4, and dielectric constant 1.5x (Figure 2). It has capacitance Cplastic. The third one uses both glass and plastic and is shown in Figure 3. This configuration has capacitance Ctotal. (15) So = 8.85 x 10-12 F/m a. Write an expression for the theoretical capacitance, Cglass: of the setup using only Fig 1 glass (Fig. 1) in terms of A, d, x, and zo. b. Write an expression for the capacitance using only plastic, Cplastic, in terms of the capacitance us using only glass, Cglass. Fig 2 Enter an expression for the capacitance of the last capacitor constructed of both plastic and glass, Com, in terms of . d. k. and so. d. Calculate the capacitance of the final Fig 3 system. Coat in nF, with A = 14.8 cm d - 0.33 mm. K = 2.7
