If you plotted vector arrows around a mass to represent gravitational field vectors, describe how the length of the arrows would change as the locations at which they are drawn become closer to the mass that produces the field. A) The arrows would become shorter and reverse their direction at some distance.
B) The arrows would become shorter.
C) The arrows would remain the same length. D)The arrows would become longer.

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 approximately 5.6x10^11 na per meter, each with a charge of e enter the axon. how many coulombs of charge enter a 1.10 cm length of axon during this process
