Its resistance increases. This is because of vibrations of the core of atoms and so they have got good influence over the movement of electrons. So conductivity gets reduced and so resistance increases. This is what we call positive temperature coefficient
Yes. An Iron core electromagnet has a stronger magnetic field then a coil. The magnetic flux is condensed and travels through the iron core with little resistance, while air provides much greater resistance.
There are several technologies, one is a wire with resistance that is wound loosly around a toroidal core (in the shape of a donut) and a contact sweeping along the surface makes electrical connection with different numbers of turns as it rotates around the "donut" thus giving variable resistance.
Core is defined as "the central or innermost part."
S waves can not travel through liquids, the outer core is a liquid, so the S waves can not travel through the outer core. You can also determine that since the outer core is all around the inner core, that the S waves can no travel through the inner core as well.
70mm2 is the cross-sectional area of each individual core of the cable. The previous numbers may relate to the number of cores. I guess we are talking SWA here?
The Intel Atom is available in both single core and dual-core varieties.The following Atom processors are single-core processors:230D410N270N280N450N470Z500Z510Z515Z520Z530Z540Z550The following Atom processors are dual-core processors:330D510

One of the single core cables benefits is high current rating. The other benefit is that the operating temperatures of single core cables are least affected by the other cables.
Nowadays the CPU's could have more than one core - they may have 2, 4 cores. Of course there still are CPUs with one core and they are called single core processors.
An example of a single core Processor is anything from Intel's first processor to the late Pentium 4 era. There are also some single core Pentium Core 2/duo line products but those were very cheap for consumers.
All CPUs branded "Pentium 4" are single-cored.
independent cores into a single package composed of a single IC. A dual-core processor contains two cores, and a quad-core processor contains four cores.
the 1.5 dual core can handle 2 threads at the same time and 3.0 single core can only handle 1 thread both of them switch threads rapidly if you have CPU-z you will find that the only difference in number of threads (the number of cores in single core is 2) short answer : the dual core is faster in multitasks the single core is faster in single task (like most of games)
Multicore processing improves processing speed
Four independent cores into a single package composed of a single IC. A dual-core processor contains two cores, and a quad-core processor contains four cores.
Quite simply, a Uni (Single) core processor has only a single primary calculations core. A Multi (Dual, quad, hexi, etc) core processor has more than one primary calculations core.
