HS Physics Unit 4 Lesson 2 Transfer Task Renee enjoys going on hikes and camping in Wisconsin to escape the busy Chicago summers. Renee's tent has the ability to hang lights in it and they have been using battery powered lights. However, the disposable batteries for the lights are quite heavy so Renee decided to look into getting a solar powered string of lights that will not need disposable batteries. The solar panel charges a battery during the day and the lights can be turned on at night. As Renee is testing out the lights, the lights begin to feel warm. Renee wonders "How is energy from sunlight transformed to make the lights turn on?" 1. The packaging of the lights stated that the solar panel has 80% energy transfer. What might this mean in terms of unusable energy? Provide evidence from the text above
