the fact right now is really true. the moon is getting further and further off Earth. if the moon hasn't exist, Egypt would snow annualy, because the Earth rotational axis depends on the moon. i'm not lying. mars is really unstable if you didn't know

A toaster uses a Nichrome heating wire. When the toaster is turned on at 20°C, the initial current is 1.50 A. A few seconds later, the toaster warms up and the current has a value of 1.22 A. The average temperature coefficient of resistivity for Nichrome wire is 4.5 10-4 (C°)-1. What is the temperature of the heating wire?

~If possible, please explain in detail how you got the answer. Thanks.

Ok say 50-75 years in the future a way was found to travel close to the speed of light and a spaceship could be built that could send a small group of humans to the nearest solar system but it would take 40 years to get there, do any of you really believe anyone in there right mind would volunteer for a mission like that?

to fill space at the speed of light. If,an undulation in the field were to occur,it would propagate outward from the electron at "C",however it could never catch up to its expanding static fields wavefront and thus propagate past it,

Can it be proven that a moving field diversion can exist in a region of space where no E-field has ever existed?

if so,would that imply that ALL photon locomotion requires the presence,however feeble,of a static electric field in order to propogate thru,or "on". ,think in terms of the curving wave on a
rope. this would also imply that a region of space that was devoid of ANY e-field would be completely dark and incapable of transmitting light or any other electromagnetic energy. .
