Hi all guys, I'm a soon to be medical doctor but I'm still concerned about some aspects of EKG (that i'm actually rewiewing :eyebrow:).
First of all I still don't understand some of the physics that lies behind it: how is it possible that the PQ tract is isoelettric if the atria are...
It's a cathode ray tube - It's the Electrostatics chapter, passage X, Q.65 (P 149).
On occasion, the electrons are made to pass through the plates undeflected. If the electrons enter the region between the plates with the same direction, but with excessive velocity:
A) they will be deflected...
help me get into med school please

If the voltage across the plates were reversed what would happen to the oil drops between the plates from the Millikan oil droplet experiment?
A- They would accelerate upward
B- They would accelerate downward
C- They would move with constant velocity upward
D- They would move with constant...
How come a particle with larger mass has a greater radius of curvature? I know that the equation shows that r= mv/qB so if m increases r increases but if a particle is heavier it deflects less so shouldn't the radius of curvature be smaller?
Conceptually I'm missing something about how distance is related to electric field and potential. Electric field is force per unit charge and potential is force per unit charge applied over a distance. Right? Well, the force changes with distance by getting larger when objects are...
I'm a bit confused on why dielectrics do what they do. I know that when the electric field of a capacitor exists, the dipoles of a dielectric orient themselves in the direction of the capacitor's electric field and, thus, the dielectric produces an electric field that opposes the...
