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.

In the physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.The principle of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces the mechanical energy is constant.n example of a mechanical system: A satellite is orbiting the Earth only influenced by the conservative gravitational force and the mechanical energy is therefore conserved. The satellite is accelerated towards the Earth with an acceleration perpendicular to the velocity.
