Alright thanks so much!

OH okay! So is the best way to represent the whole plane of vectors to use the zero vector?

I understand this, and can see this in all the formulas and such that are related to the cross product. But I can't wrap my head around it conceptually. Shouldn't there be a ton of different vectors that are perpendicular to both of the parallel vectors?

Wouldn't that have to mean that the angle between is either 0 or pi or any multiple of pi?

Hello, PF! I had a quick question that I hoped maybe some of you could help me answer. The question is simple: Why is the cross product of two parallel vectors equal to the zero vector? I can see this easily mathematically through completing the cross product formula with two parallel...

Alright then, so V = IR. So I get V = 5000 V. Then I used V2/R and got 2.5 MW as my answer. Thanks ! :smile:

Sorry, I meant to type V2/R. How would one then go about calculating the potential drop V?

Homework Statement A high voltage powerline operates at a 500000 V-rms and carries an rms current of 500 A. If the resistance of the cable is 0.05Ω/km, what is the resistive power loss in 200 km of the powerline. V = 500000 V-rms Irms = 500 A R/x = 0.05Ω/km x = 200 km Homework Equations P =...

Hello everyone on these wonderful forums! I have used your site plenty of times throughout this past semester as I am currently taking the first semester of Physics I have ever taken! At first, I really hated the class. The first couple chapters were all just kinematics, and I thought to myself...
