Kayla says that turning on a radio involves an energy transformation, but joey says that energy cannot be transformed.
which of the following arguments can kayla use to prove she is correct?
a
the radio has potential energy when it is plugged into an outlet, and it is transformed into kinetic energy when the radio is turned on.
b
the radio has potential energy when it is plugged into an outlet, and it is transformed into sound energy when music is played using the radio.
c
the radio needs electrical energy to work, but the electrical energy is transformed into mechanical energy that is used to find a radio station.
d
the radio needs electrical energy to work, but the electrical energy is transformed into sound energy that is used to hear the songs that are playing.
