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.

Mechanical energy can take the form of kinetic energy as in the energy of an object's movement or it can take the form of potential energy by virtue of the stored energy of an object in a particular position. Mechanical energy can be seen in the form of a pendulum, landslides, and avalanches etc.
