Each of the gears a and b has a mass of 2.4 kg and a radius of gyration of 60 mm, while gear c has a mass of 12 kg and a radius of gyration of 150 mm. a couple m of constant magnitude 10 n × m is applied to gear b. determine the number of revolutions of gear c required for its angular velocity to increase from 100 to 450 rpm and the corresponding tangential force acting on gear a. (round the final answer to two decimal places.)

the answer you are looking for is d. there are no holes for blood to enter or leave the system. your welcome

the kind of relationship between atmospheric  density and altitude is inverse relationship. this means a surge in either will cut the other factor. density is mass per unit volume, it is hard to compute with only altitude 1,291 kilometers given. also, we could also use temperature and pressure to resolve density but they are not delivered.
