As a part of a research, natasha initially had difficulty falling asleep in the sleep lab, but finally drifted into sleep and was not awakened when a student researcher knocked a can of soda off the desk. the electroencephalograph (eeg) is displaying theta waves with occasional sleep spindles. the researchers feel confident that natasha is:

Expalined

Explanation:

When electroencephalograph (EEG) is displaying theta waves with occasional sleep spindles, the  patient is in deep relaxation and in the second stage of sleep where there is a dominance of theta waves and occasional burst of sleep spindles. In this stage small distubances and sound does not break the sleep. In addition appearance of K- complexes is often associated with stage two sleep.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
