Two straight and infinitely long conductors are on the same plane and are perpendicular to each other, as shown in
figure. The distances are AM = 4.0 cm and QA = 2.0 cm, and the
current strengths i1 = 48 A and i2 = 42 A. The module of
magnetic field vector at point A is from:

Aray of light traveling parallel to the principal axis of a concave mirror will be reflected through the mirror's

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
