(a) Explain how you can use the graph of position versus time in Figure 2.54 to describe the change in velocity over time, Identify (b) the time (t_a, t_b, t_c, t_d, or t_e) at which the instantaneous velocity is greatest, (c) the time at which it is zero, and (d) the time at which it is negative,

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?
