Investigators are researching the appearance of a strange movement of objects in what the local community considers a haunted house.
the owners of the house attribute the cause to poltergeists; others blame overly strong magnetic fields could be the cause.
as a scientific investigator of paranormal claims, you decide to investigate. you will start by focusing on magnetic fields.
using a coil made of 219 turns of single-strand copper wire, you use a motor to rotate the coil at a constant angular speed of 40.0 revolutions per second at various orientations and locations throughout the room. in one particularly signficant orientation, you notice a maximum induced voltage of 3.15 v appearing in the coil.
if the radius of the coils is 1.00 cm, how strong was the magnetic field that produced this emf?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
