The atomic mass of a nitrogen atom (n) is 14.0 u, while that of an oxygen atom (o) is 16.0 u. three diatomic gases have the same temperature: nitrogen (n2), oxygen (o2), and nitric oxide (no). rank these gases in ascending order (smallest first), according to the values of their translational rms speeds.
a. n2, o2, no
b. o2, no, n2
c. o2, n2, no
d. no, n2, o2

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
