1. ### A 500.0 pF capacitor consists of two circular plates of radius 0.30 mm?

you use C = εo(A)/d 5 x 10^-10 = (8.85 x 10^-12)(π)(0.30 mm)^2/d d = ((8.85 x 10^-12)(π)(0.30 mm)^2)/5 x 10^-10 d = 0.0050 μm so the answer is c) 0.0050 μm

8. ### Here is q pf vector what a confusing Q yr anyone answer me!?

since the magnitudes are equal, the resultant is at an angle half way between them, or π/3 or 60º. And the component of each one is M cos 60 or 0.5. Add the two 0.5's to get 1.0, equal magnitude.

9. ### Suppose a resistor of 10 ohms, a capacitor of 820 pF , and a coil of 10 microHenry are in parallel. The frequen?

There are (3) devices here of which (2) are frequency dependant; the capacitor and the inductor. The capacative reactance Xc = 1 / (2 * pi * Freq * C ) = 1 / (2 * pi * 10E6 * 820E-12) = 194.0914 ohms or -j194.0914 as a phasor. The...

1/Z=1/R+1/jXL-j/XC where Xl=2 pi f L and XC=1/2 pi f C. Just plug in the numbers and solve for Z. The complex math isn't hard, but it does take a little more work.
