I need to get interested in some kind of hobby or good pass time?

Question by Amanda: I need to get interested in some kind of hobby or good pass time?
I find myself having nothing to do all the time. I do all my college work then I just sit on the computer all night. What is something fun and/ or interesting to get involved in. I am 19 and a junior in college, I am trying to be more healthy and fit as well so if there are any activities that involve bettering yourself I am up for it as well. Thanks!

a model electric train makes one complete pass around a circular track every 15 seconds….?

Question by moniquew93: a model electric train makes one complete pass around a circular track every 15 seconds….?
a model electric train makes one complete pass around a circular track every 15 seconds. the train’s motor has a resistance of 6.0ohm and is connected to a 70.0V source. How much energy will the train use in 12 complete passes around the track?

Answer by kirchwey
This question cannot be answered. Model-train motors don’t draw the huge wattage implied by the voltage and resistance, which = V^2/R = 816.67 W. At running speed the motor would generate a back EMF which would substantially reduce the actual voltage across the internal resistance. See the ref.
EDIT: The input data are not necessarily crazy, just incomplete. What’s crazy is the assumption that the given V is applied across the given R continuously; it actually would only happen momentarily at startup.

does electricity pass through the tracks on a electric train?

Question by Knights Templar: does electricity pass through the tracks on a electric train?
what creates the circuit with overhead wiring on electric trains and if it passes through the tracks why whats stops electrocution of people walking on tracks

Answer by Bob B
The high voltage to drive the train is carried on the conductors hung above the trackway. Since the tracks only provide a path to carry the current to ground, they aren’t at an elevated voltage level.
