If GFR is over 90, the kidneys are healthy and functioning normally. A kidney score of 60-89 means the person should be monitored, and if GFR scores falls to less than 60 for a three-month period, that is an indicator of chronic kidney disease.
Posted on. (Answer #2). Sound is a form of mechanical energy because the source of sound is vibration. Mechanical energy consists of gravitational potential energy and kinetic energy. Vibrating particles have kinetic energy which is a form of mechanical energy.osted on. (Answer #2). Sound is a form of mechanical energy because the source of sound is vibration.

Sound is mechanical energy, and anything that exhibits movement can make sound. But the sound has to have something to travel in. A gas or a liquid or a solid is a medium, and â¦ the sound will travel in them (or will be conducted through them).But something must move to supply that mechanical energy that will create (will become) a sound. There are countless examples. Pluck the string on an instrument.ut the sound has to have something to travel in.
