IB Physics Comic FinalBy: Nora Ibach
Hey Surfer Sarah! I am so excited to go tubing on the water today looks like a nice day
Yeah Tugboat Todd I can't wait!
Yeah! I have to make sure there is enough tension in the rope to whip you in a circle
Tugboat Todd, can we do donuts?
Oh no! The engine is smoking! We need to recharge it!
I can help you! I will run a wire from my boat battery to yours! Although there may be some resistance. I have a 9 volt battery that will flow at a current of 3 amps
Well we can figure out the resistance by using the voltage divided by the current, so the resistance is 3 ohms
Great! Now we need to figure out how to get the current to flow from my boat to yours
Since we want the the current to travel west, the magnetic field must point away from you when you send it our way!
