Mrs. brown's class is studying magnets and electricity. at the end of the unit claire states that magnets and electricity are both non-contact forces like gravity, but they are not related other than that. sammy says that magnets and electricity are closely related, but isn't sure how. if you were mrs. brown, how would you explain the relationship between magnets and electricity to the class? check all that apply.
question 7 options:
magnets can create electricity and electricity can create a magnetic force.
both electric charges and magnets do not have to touch an object in order to exert a force on it.
electromagnets use electricity to create a magnetic force.
generators convert electrical energy into magnetic energy.

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
