Question

Question 3 of 15 Map Sapling Learn macmillan learning ing ab technician is testing new energy drink formulations on a series of hamsters. The hamsters are given certain amount of the beverage, and then placed on exercise wheels to observe their energy levels. Due to poor planning, however, each exercise wheel is a different size. The names of the hamsters, the diameter of each of their wheels, and the technician's notes are in the table below. Rank the period of rotation of each hamster's wheels, and the speed of each hamster, from highest to lowest Name Archimedes Bohr Compton Dirac Wheel Diameter (cm)Technician's Notes 23.0 16.0 13.0 11.0 2 rotations in 1 S 7 rotations in 6 s 25 rotations in 4 s 8 rotations in 3 s Longest Fastest Period Speed Shortest Slowest Bohr Archimedes Dirac Compton Compton Archimedes Dirac Bohr

Explanation / Answer

archimedes: T = 1 /2 = 0.5 sec

v = (2 pi / T) r = 1.445 m/s

Bohr : T = 6/7 = 0.86 sec

v = 0.586 m/s

Compton : T = 0.16 s

v = 2.55 m/s

Dirac: T = 3/8 = 0.375 s

v = 0.92 m/s

Period : Bohr archimeded Dirac Compton

Speed : Compton archimedes Dirac bohr
