Homework Statement Hi, This isn't so much an actual problem, just more of a general question. Can anyone give me a layman's explanation of what a short circuit is and how a circuit breaker deals with that? Or, can anyone refer me to any sources that can? I have taken high school physics...

Ok, sorry about all those questions, I'm new to all this, but I suppose that DV = DX/Dt would give you the roundtrip value of 450. So if you halve that to find out just the distance to the stoplight, that would give you the expected answer of 225.. Thanks again!

Better yet, why couldn't you just use DV = DX/ Dt ? That doesn't give you the correct answer though... if you use 30m/s = DV and 15s = Dt

A Pm??

Oh, ok, so you can't assume g = 10m/s^2 unless explicitly stated then?

Hi, The 10m/s^2 is just the acceleration due to gravity (normally 9.8m/s^2)

Hi all, I have (what should be) a relative simple question regarding the use of Kinematic equations: The problem is stated as: A station wagon, initially traveling east at 30m/s, decelerates uniformly until coming to a complete stop at a traffic light. How far was the driver from the...

Thanks for that additional example. Definitely helped. Just one quick question: What do you mean by "the higher resistor drops more voltage than the lower resistor"... by "drops more" what do you mean? Thanks again, _G

Two light bulbs, one 60 watt bulb (higher resistance) and one 100 watt bulb (lower resistance) are placed in series. A current is run through them. Which bulb glows brighter? The answer detailed that: The bulb with more resistance would draw more current, thus get more voltage, so the 60...
