A changing magnetic field induces an emf of 5.0 V in a single-loop of wire. Suppose the single loop were replaced by one continuous wire wrapped to form a coil of five loops, each with the same size and shape as the original loop, and placed in the same changing magnetic field and with the same orientation as the single loop. What would be the magnitude of the induced emf in the coil

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

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
