Modern wind turbines generate electricity from wind power. the large, massive blades have a large moment of inertia and carry a great amount of angular momentum when rotating. a wind turbine has a total of 3 blades. each blade has a mass of m = 5500 kg distributed uniformly along its length and extends a distance r = 46 m from the center of rotation. the turbine rotates with a frequency of f = 13 rpm.(a) enter an expression for the total moment of inertia of the wind turbine about its axis of rotation, in terms of the defined quantities.
(b) calculate the total moment of inertia of the wind turbine about its axis, in units of kilogram meters squared.
(c) enter an expression for the angular momentum of the wind turbine, in terms of the defined quantities. sig. gif? tid=0n86-9a-18-43-94ed-17253
(d) calculate the angular momentum of the wind turbine, in units of kilogram meters squared per second.

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.
