Which of these best describes the flow of charge through a circuit? A
Charged particles are already present in the circuit components and they move in the same direction all at the same time.
B
Charged particles are already present in the circuit components and they move one at a time in a straight line.
C
The battery provides the charges to the circuit and they move in a straight line, one after the other.
D
None of these are correct.

answer and explanation;

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
