Aclosely wound rectangular coil of 100 turns has dimensions of 27.0 cm by 50.0 cm . the plane of the coil is rotated from a position where it makes an angle of 37.0 ∘ with a magnetic field of 1.20 t to a position perpendicular to the field. the rotation takes 9.00×10−2 s . (note that the coil is perpendicular to the area vector of the coil.) what is the average emf induced in the coil?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
