Physical science was once defined as "the science of the nonliving world." Explain why that definition is no longer sufficient.

A normal polarity magnet moves toward a stationary coil at 20 cm/s, and induces a maximum current of - 8 mA.

Emilio's teacher told his class that a controlled experiment's results are valid only if one factor in the experiment is changed and all the other factors remain constant.

A 1.5-kg object moves up the y-axis at a constant speed. When it reaches the origin, the forces at 37° above the in the at 45° below the and in the are applied to it.

Briefly describe how a sound wave is formed.
