When 2 vectors are the same size (have the same magnitude) and are moving in opposite directions along the lead axis (in line with the positive electrode lead), what will appear on the ECG recording?
A) negative deflection
b) positive deflection
c) isoelectric (flat) line
The ECG recording will display positive deflection as the lead axis is in line with the positive lead. It happens to negative deflection if it moves away from the positive lead.

When transverse positive and negative pulses that have the same symmetric shape and size but travel in opposite directions meet, is it necessary that there be a moment when the string or wire on which they move is flat? If so, how do the pulses "know" to continue moving on the string? Two people on each end of a long rope send off a wave pulse. If both wave pulses are on the same side of the rope, describe what...

A proton and an electron have charges e and –e. They are moving with the same speed in opposite directions, as you can see above. At a particular moment, the proton is at a distance d directly above the electron. At this moment, the velocity of the electron points in the positive x-axis and the velocity of the proton points in the negative x-axis. A. What is the direction of the magnetic field from the electron at the location of...
1.) Vectors Can the x or y component of a vector ever have a greater magnitude than the vector itself has? Yes. The x component can, but the y component cannot. Yes, but only when the x and y components have equal magnitudes. Yes. Both components can. Yes. The y component can, but the x component cannot. No. Neither component can. 2.) A force vector has a magnitude of 370 newtons (N) and points at an angle of 53.0° below...
