What can accurately be said about a resultant wave that displays both reinforcement and interference? a. the component waves have different frequencies. b. maximum interference occurs where the troughs of the two component waves are in phase. c. molecules remain in their normal positions at spots of reinforcement. d. the crests of the two component waves are in phase where interference occurs in the resultant wave. mark for review (will be highlighted on the review page)

Argon is adiabatically compressed from an initial volume of 16 liters to a final volume of 2 liters. by what factor do the following quantities change? do they increase or decrease? (a) the rms speed (b) the thermal energy of the gas (c) the molar specific heat cv (d) the pressure

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
