Neurons are components of the nervous system of the body that transmit signals as electrical impulses travel along their length. These impulses propagate when charge suddenly rushes into and then out of a part of the neutron called an axon. Measurements have shown that during the inflow part of this cycle, approx. 5.6 * 10^11 Na+ (sodium ions) per meter, each with charge +e enter the axon. How many coulombs of charge enter a 1.5 cm length of the axon during the process?
