An air-filled parallel-plate capacitor with plate separation d and plate area A is connected to a battery that applies a voltage V₀ between plates. With the battery left connected, the plates are moved apart to a distance of 10d. Determine by what factor each of the following quantities changes:

(a) V₀;

(b) C;

(c) E;

(d) D;

(e) Q;

(f) ρ_S;

(g) W_E.
