Answer:
the branch of mechanics concerned with the interaction of electric currents with magnetic fields or with other electric currents.
Explanation:
Just look at the graph, and find a curve that has fallen to
half of its original value 95 = 47.5 in 13 B years.
Do I really hafta tell you which one it is ?
It's curve ' C ' .
Energy and Work Energy is the capacity to do work or to produce heat. Internal energy is the sum of kinetic energy and the potential energy. ... The KE would increase because heating something causes an increase in temperature.
Answer: The second option.When
the current flows up the wire, the magnetic field flows out on the left
side of the wire and in on the right side of the wire.Explanation:
The first figure that I copy here with is the figure corresponding to this question.
The thumb is pointing upward.
The rule is that the thumb aims to the direction of the flow of current and the other fingers give the field lines.
The second figure that I attach is a free image from internet and it shows the direction of both the current and the fiedl lines.
So, the conclusion is that
the current goes upward the wire and the field lines go out of the paper (screen) for the points to the left of the wire and in on the right side of the wire.
Yes. That's a true statement. Ultrasound is indeed the name given to sounds with frequencies above the human range of hearing.
Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans can't hear it.
