Two convex lenses are placed 15 cm apart. the left lens has a focal length of 10 cm, and the right lens a focal length of 5 cm. an object is 50 cm to the left of the left. lens. where does the image from the right lens appear? is this image real or virtual? this setup is essentially a simple telescope, (the shorter focal length lens being the one you look through) so what does your answer tell you about looking at a nearby object through a telescope? (hint: treat the image from the left lens as the object for the right lens.)

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.
