A wire carrying current I from south to north then passes directly over top of the compass. As a result, the compass needle A) deflects toward the east B) deflects toward the west C) flips around 180 o and points south D) remains undeflected pointing north.

The mass of a muon is 207 times the electron mass; the average lifetime of muons at rest is 2.21 μs. in a certain experiment, muons moving through a laboratory are measured to have an average lifetime of 7.04 μs. for the moving muons, what are (a) β (b) k, and (c) p? the rest energy of the electron is 0.511 mev.

The law of conservation of energy states that energy cannot be created or , energy can be from one substance to another. the first blank is ' destroyed ' and for the second blank is ' transferred '
