A characteristic of the open-loop system is that it does not use feedback to determine if its output has achieved the desired goal
of the input. This means that the system does not observe the output of the processes that it is controlling. Closed-loop systems
employ feedback and a reference of correctness. Deviations from the norm are detected and corrections made in order to
maintain a desired output.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

Ryan is examining the energy of the particles in a bar of gold. what is ryan most likely studying?

Heterogeneous mixture with larger particles that never settle is
