The figure above illustrates a toy seesaw made with a candle. The candle is lit at both ends and, initially, one end is left lower than the other. As the candle burns, the seesaw moves up and down. The energy transformations that occur in this process are:
The potential energy of the candle wax is converted into thermal energy, which is then converted into radiant energy and finally into kinetic energy of the seesaw. a) true b) false
A alternativa correta é a letra A) verdadeiro. Durante o processo descrito, a energia potencial da cera da vela é convertida em energia térmica, que é convertida em energia radiante e, finalmente, em energia cinética da gangorra.
