Storm radios are designed with backup batteries so that they can be used
even in the case of a power outage. Which sequence best illustrates the
energy conversions during a power outage?
A. Electrical energy is converted into chemical potential energy,
which is then transferred into the energy of the sound waves.
B. Chemical energy in the battery is transferred to electrical energy,
which is then transferred into the energy of the vibrating air
molecules in the sound waves.
C. Electrical energy is converted into mechanical energy of the
speakers, which is then transferred into sound wave energy.
D. Chemical energy in the battery is transferred to kinetic energy of
the air molecules, which is then transferred in my sound.
