Awave travels through a medium and displaces the particles perpendicular to the direction in which the wave is traveling. this type of wave is a transverse wave because of the direction that the particles are being displaced as the wave travels. longitudinal wave because of the way the particles are displaced as the wave passes through. transverse wave because it is not traveling in a vacuum and the particles are moving

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid
