Ameteoroid, heading straight for earth, has a speed of 14.8 km/s relative to the center of earth as it crosses our moon's orbit, a distance of 3.84 × 108 m from the earth's center. what is the meteroid’s speed as it hits the earth? you can neglect the effects of the moon, earth’s atmosphere, and any motion of the earth. (g = 6.67 × 10 -11 n ∙ m2/kg2, mearth = 5.97 × 1024 kg)

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.
