The hour and minute hands of the clock in the famous parliament clock tower in london are 1.7 m and 3.4 m long and have masses of 89 kg and 60 kg, respectively calculate the magnitude of the torque around the center of the clock due to the weight of these hands indicating 3 h and 1 min; i. e., 3: 1 o’clock. assume the clock hands can be modeled as uniform thin rods and at 3: 00 o’clock, the hour hand is precisely 90◦ from the vertical. the acceleration of gravity is 9.81 m/s 2 . answer in units of n · m

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.
