Which of the light bulbs (if any) in (Figure 1) are connected in series to each other?

Check all that apply.

Part b) asks for the electric field inside the cell membrane(i.e.,dielectric) given V=85mV, K=10 and d=7.5nm. The Cramsteranswer isE=V/d. What happened to the dielectric? Shouldn't theanswerbe;
E = E_o/K = (V/d)/K = V/Kd = 85mv/(10)(7.5nm) = 1.13x10⁶ V/m?

At what temperature would the rms speed of H₂molecules equal 11,200 m/s ( the Earth's escape speed)?

a) 10² K

b) 10⁶ K

c) 10⁴ K

d) 10⁸ K
