A wind engineer measured the amount of kinetic energy a prototype turbine produced when placed in locations with different average wind speeds around the United States. A graph of the results is found above. What
inference can be made about operating this type of turbine at a location with an average wind speed of > 20
kph?

you can't see the options

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
