Since answers a through d are generally true for every energy change, I%26#039;d have to go with e. They%26#039;re all just different ways of describing the inefficiencies encountered in performing energy conversions.
Whether you term it %26#039;energy%26#039; or %26#039;usefulness%26#039;, the meaning is the same. Whether you use the term %26#039; lost%26#039; or %26#039;wasted%26#039;, again, the intent is the same. 0% 0 Votes -
