A salvage ship is attempting to raise an iron anchor off the ocean floor. The anchor has a mass of 560kg and the density of iron is 7800 kg/m^3. The cable used to lift the anchor can support a weight of 5000N before breaking. Use 1025kg/m^3 as the density of sea water . a)Will the cable be able to support the anchor while it is completely submerged? b)What is the percentage of the anchor will be out of the water when the cable breaks?

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?

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.
