All of the following are examples of energy transformations EXCEPT OB O A. Electric energy from an outlet becomes electromagnetic energy when it is used to power a light bulb. Ajack in the box is cranked down until the spring inside is compressed. The spring releases turning elastic potential energy into kinetic energy when the toy moves. O C. Stored potential energy in a lighter is ignited to create light and thermal energy. OD. A child on a sled posesses kinetic energy as they slide down a snowy hill.​
