what does this sentence mean The flashlight shines brighter than before after Holly changed the batteries.
The sentence suggests that the flashlight is emitting a brighter light after the batteries were changed, indicating improved performance with new batteries.
The sentence 'The flashlight shines brighter than before after Holly changed the batteries' implies that the intensity of the light emitted by the flashlight has increased.
This improvement in brightness likely occurs because new batteries provide a higher voltage than old ones, allowing more current to flow through the flashlight's bulb, which in turn results in a brighter light.
This is an expected observation as battery-powered devices tend to perform better with fresh batteries compared to when they are nearing the end of their charge.
