What will occur when the trough of Wave A overlaps the trough of Wave B?

A: Destructive interference will occur, causing the new wave to have more energy than Wave A or Wave B.

B: Constructive interference will occur, causing the new wave to have more energy than Wave A or Wave B.

C: Destructive interference will occur, causing the new wave to have less energy than Wave A or Wave B.

D: Constructive interference will occur, causing the new wave to have less energy than Wave A or Wave B.

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
