Nerve cells transmit electric signals through long tubular axons. These signals propagate due to the sudden rush of Na* ions, each with charge +1.60 x 10 19 C per ion, into the axon. Measurements have revealed that about 5.86 x 101 Na* ions can enter each meter of the axon during a time of 0.0100 s. What is the current during this inflow of charge in a meter of axon in µA? Give the answer with two decimal digits and no unit. (1 × 10 ° A = 1 µA)

Nerve cells transmit electric signals through long tubular axons. These signals
propagate due to the sudden rush of Na" ions, each with charge +1.60 x 1019 C per
ion, into the axon. Measurements have revealed that about 5.86 x 1011 Na ions can
enter each meter of the axon during a time of 0.0100 s. What is the current during
this inflow of charge in a meter of axon in µA?
Give the answer with two decimal digits and no unit. (1 × 10° A = 1 µA)
