Atechnician wearing a brass bracelet enclosing area 0.00500 m2 places her hand in a solenoid whose magnetic field is 2.70 t directed perpendicular to the plane of the bracelet. the electrical resistance around the circumference of the bracelet is 0.0200 . an unexpected power failure causes the field to drop to 0.81 t in a time of 19.0 ms. (a) find the current induced in the bracelet. a (b) find the power delivered to the bracelet. (note: as this problem implies, you should not wear any metal objects when working in regions of strong magnetic fields.) w

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
