Web1 day ago · We describe below the specific manifestations of acoustic effects that may occur based on the activities proposed by Empire Wind. Richardson et al. (1995) described zones of increasing intensity of effect that might be expected to occur, in relation to distance from a source and assuming that the signal is within an animal's hearing range. WebIf we add the right amount of energy, this electron can jump up to a higher energy level. So now this electron is a distance of r3, so we're talking about the third energy level here. …
