What is the angular momentum of a figure skater spinning (with arms in close to her body) at 3.5 rev/s,assuming her to be a uniform cylinder with a height of 1.5 m,a radius of 16 cm,and a mass of 55 kg.1 [___]kg·m2/s(b) How much torque is required to slow her to a s...
In this paper a graph is outlined using the new gyrochronology in the general theory of stellar metamorphosis using a preliminary method for determining if a star is hosting life. As well, it outlines which stages of a star's evolution life may be occurring inside that star. In effect, ...
Classic mechanical gyroscopes are mechanical structures consisting of a spinning rotor that is free to assume any orientation. Because of the conservation of angular momentum, the orientation of the rotor is not affected by tilting or rotation of any part of the outer frame or inner gimbals....
it would still take something like 1 million years to slow the planet down to a stop," Levy said.It's virtually impossible for any objects in space to halt the Earth's rotation before then. "The angular momentum of the Eart...
A thin lens with a focal length of 6.00 cm is used as a simple magnifier. (a) What angular magnification is obtainable with the lens if the object is at the focal point? 395 Textbook Question BIO A person can see clearly up close but cannot focus on obj...
Angular momentum of the satellite about the centre of the orbit is L = mvr, where v is the orbital speed of the satellite. For motion in a fixed orbit, centripetal force = force of attraction due to gravity or,mv2r=GMmr2 or, mv2r = GMm or, (mvr)2= GMm2r ...
The Finite-Difference Time-Domain (FDTD) method is a rigorous and powerful tool for modeling nano-scale optical devices. FDTD solves Maxwell’s equations directly without any physical approximation, and the maximum problem size is limited only by the ext
握手也有先后顺序，应由主人、年长者、身份高者、妇女先伸手，客人、年轻者、身份低者见面先问候，待对方仲出手后再握。多人同时擂手，切忌交叉进行，应等别人握手完毕后再伸手。男子在握手前应先脱下手套，摘下帽子。握手时应双目注视对方，微笑致意。（ ）
