Mini here phones and signed in the way pictured below a coil of wire carrying an electric current is wrapped around a diamond speakercone the Cone and Coyle are placed near a small bag sound is generated by the speaker cone vibrating in different ways the Cone vibrate as different magnetic forces act on a current caring coil why do the magnetic force is acting on the coil change as a current running through the coil changes a because the current generates a magnetic field around the coil be because the coils of wire are not usually attracted to magnets see because of current causes a magnet to gain power

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
