Helpp When a pot of water sits on a hot stove, the metal pot is heated, and then transfers its heat to the water. A student claims that conduction is the only type of heat transfer occurring. Which statement explains why the student's idea is incorrect?

Conduction cannot occur between two different phases of matter.
The water transfers heat within the pot by convection.
Water cannot be heated by electromagnetic radiation.
Metal is a poor conductor of heat.

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.
