The graph shows the distribution of energy emitted by a star. A graph with wavelength in micrometers from 0 to 3 on the x-axis. There is intensity on the y-axis. There are 3 curves. There is a very low curve that starts at the origin, peaks at a wavelength of .9 micrometers. There is an area that starts at the x-axis and goes vertically labeled visible light.
Which is the best conclusion to draw about the star?

1. It has a lower temperature than the Sun because its peak wavelength is longer than the Sun’s.
2. It has a lower temperature than the Sun because its peak wavelength is shorter than the Sun’s.
3. It has a higher temperature than the Sun because its peak wavelength is longer than the Sun’s.
4. It has a higher temperature than the Sun because its peak wavelength is shorter than the Sun’s.

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.

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
