Find the work w1 done on the bltwo tugboats pull a disabled supertanker. each tug exerts a constant force of 2.10×106 n , one at an angle 10.0 ∘ west of north, and the other at an angle 10.0 ∘ east of north, as they pull the tanker a distance 0.890 km toward the north. ock by the force of magnitude f1 = 80.0 n as the block moves from xi = -5.00 cm to xf = 6.00 cm .

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?

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.
