An air-filled capacitor consists of two parallel plates, each with an area of 10.0 cm2, separated by a distanceof 2.00 mm. A 20.0-V potential difference isapplied to these plates. Calculate (a) the electric fieldbetween the plates, (b) the surface charge density,(c) the capacitance, and (d) the charge on each plate.

Objects a and b are visible in the night sky. six months later they are still visible, but object b shows less parallax than object a. which object is closer? a. a b. b c. you would need to wait another six months in order to figure this out. d. you would need to know the objects' angular diameters in order to figure this out.

Substances that assume the shape of their container, but do not have a definite size are called
