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 Energy- is produced when an object is made to vibrate. Sound energy travels out as waves in all directions. Sound needs a medium to travel through, such as air, water, wood, and even metal! Examples: Voices, whistles, horns and musical instruments. C Chemical Energy - is really a form of potential energy and is the energy stored in food, gasoline or chemical combinations. Examples: Striking a match, combining vinegar and baking soda to form CO2 Gas, breaking light sticks releases chemical energy. R. Radiant Energy - is a combination of heat and light energy. Light energy, like sound energy, travels out in all directions in waves. Examples: A light bulb, the glowing coils on a toaster, the sun, and even headlights on cars. E. Electrical Energy - Energy produced by electrons moving through a substance is known as electrical energy.
