Question

An air-filled capacitor consists of two parallel plates, each with an area of 7.6 cm2, separated by a distance of (a ) If a 15.0 V potential difference is applied to these plates, calculate the electric field between the plates. (b) What is the surface charge density? (c) What is the capacitance? (d) Find the charge on each plate. kV/m nC/m2

Answer 1

a) E681 82 NC b) dl

Answer 2

The 24 consonant sounds comprise six stops (plosives): p, b, t, d, k, g; the fricatives f, v, θ (as in thin), ð [eth] (as in then), s, z, ∫ [esh] (as in ship), Ʒ (as in pleasure), and h; two affricatives: t∫ (as in church) and dƷ (as the j in jam); the nasals m, n, ŋ (the sound that occurs at the end of words such as young); the lateral l; the postalveolar or retroflex r; and the semivowels j (often spelled y) and w. These remain fairly stable, but Inland Northern American differs from RP in two respects: (1) r following vowels is preserved in words such as door, flower, and harmony, whereas it is lost in RP; (2) t between vowels is voiced, so that metal and matter sound very much like British medal and madder, although the pronunciation of this t is softer and less aspirated, or breathy, than the d of British English.
