fredluis 2019-08-08 12:36:37 | I\'m surprised no one noticed this one... As x -> infinite, acceration must approach g (a -> g), so choice is the only possibility. tree trimming | |
joshuaprice153 2019-08-08 06:23:04 | I will must share this blog and the information i found here really has no value in money but more than it. Thanks for this nice effort which you put here in the shape of this post. security guard Orlando | |
nakib 2012-09-29 12:56:20 | I solved it using Maxwell's equations. The given equation is Ampere's law in differential form. You can see the electric current term J in there. This current term is enabled by the fact that there are electric monopoles. Monopoles are allowed to exist if . Only (A) has that property. If you can remember this, this method is at least as quick as using the vector identity mentioned by Yosun. | |
pam d 2011-09-23 19:46:58 | Just to be clear for people that might be foggy on vector calc, the answer is (A) for reasons already explained. | |
casanovo 2008-10-29 14:52:17 | The identity didn't show up, so here it is in words:
The divergence of the curl is always zero. | |
