You mean.. BIl = mg 0.5 I = 1.8E-3 I = 0.0036 A ?

Homework Statement A wire extends horizontally from east to west. The mass of its meter is (0.18)g and it carries a current of (1)A. If the wire is in a magnetic filed (0.5)T that heads horizontally upwards, determine the least current that makes the magnetic force equal the wire weight...

I knew it :smile: the problem was that i haven't known that the wavelengths make out the radius as this is my first encouter with circular waves anyways thanks a lot Doc Al cya :cool:

I don't think i get it :confused: is it that i reversed the final result 25->0.04 (this happens all the time and its really annoying) or i simply skipped a step that i can't figure?

aha! so: v = 1.6/4 = 0.4 m/s and... lambda = 0.4/10 = 25 m i hope i got at least closer ^^

[SOLVED] Wave problem Homework Statement a small stone fell into alake causing 40 waves after 4 seconeds, if the radius of the outter circle is 1.6 meters, find the length of the occurred wave and its velocity Homework Equations The Attempt at a Solution well i got two...
