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.

The mechanical energy of a hammer gives the hammer its ability to apply a force to a nail in order to cause it to be displaced. Because the hammer has mechanical energy (in the form of kinetic energy), it is able to do work on the nail. Mechanical energy is the ability to do work.
