Is There a Future for Mechanical Beings? In today’s fast-paced society we ask ourselves a series of questions: Did I let the dog out? What’s for dinner tonight? How am I going to find the time to finish my English essay? I believe these questions can be answered by the developmental studies of machines known as robotics. The machines themselves are called robots. Robots are mechanical beings capable of operating as humans. Throughout my life I have been fascinated by Artificial Life (A.L

Defn. of Digestion: the process whereby a biological entity processes a substance‚ in order to chemically convert the substance into nutrients. It usually involves mechanical manipulation and chemical action. Mechanical Digestion What is it? This type of digestion involves the mixing‚ grinding or crushing of large pieces of food into smaller places. Why does it take place? So that the food we consume is broken down into smaller pieces before we swallow it which in turn makes process of

Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature
