Consider the power dissipated in a series r–l–c circuit with r=280ω, l=100mh, c=0.800μf, v=50v, and ω=10500rad/s. the current and the voltages in this circuit are not in phase with each other. using the values given, the phase angle ϕ was found to be 73 ∘, and the current amplitude i was found to be 5.1×10−2 a . calculate the power factor and the average power to the entire circuit and to each circuit element.

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.
