17. The wind possesses energy by virtue of its mass and speed. For example, a cubic meter of air moving at 10m/s has about 60 J of kinetic energy. Which of the following energy values might one expect for this same air after flowing through a mechanical device, such as a wind turbine? a. 0 J b. 30 J c. 60 J d. 120 J​

The law of conservation of energy states that energy cannot be created or , energy can be from one substance to another. the first blank is ' destroyed ' and for the second blank is ' transferred '

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.

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?
