I = MR ^ 2» [We were studying conservation of angular momentum when I gave this quiz]

A slowly rotating red giant star will have the same angular momentum when it becomes a tiny, fast rotating neutron star.

When circularly - polarized light is sent into such a waveguide, its polarization state continues to change as it propagates in the waveguide and consequently, the photons exchange spin angular momentum with the waveguide.

Stars also spin, and when a large one collapses, the resulting black hole must spin even faster, since the same amount of angular momentum is stuffed into a much smaller amount of space.

The double pulsar PSR J0737 — 3039A / B consists of two neutron stars in a highly relativistic orbit that displays a roughly 30 - second eclipse when pulsar A passes behind pulsar B. Describing this eclipse of pulsar A as due to absorption occurring in the magnetosphere of pulsar B, we successfully used a simple geometric model to characterize the observed changing eclipse morphology and to measure the relativistic precession of pulsar B's spin axis around the total orbital angular momentum.

A light beam with orbital angular momentum looks a bit like a helix or coil when its component waves are mapped out.

But when a contact binary merges, the angular momentum of the orbiting stars spins up the single merged star.

«Students who actually got to hold this bicycle wheel did much better — in a statistically significant way — when tested on angular momentum problems,» Singer said.

When such a photon collides with a sodium atom, the sodium's own peculiar properties allow it to absorb the photon's angular momentum.

Or, gravitational interactions between Earth and Venus when the planets pass near each other in orbit may be sapping our neighbor of its angular momentum.

When a star leaves the main sequence, its future evolution is precisely determined by its mass, rate of rotation (or angular momentum), and chemical composition and whether it is a member of a close binary system.

When stars form from a giant cloud of gas and dust, the angular momentum of the cloud carries over to all the objects that form from the cloud, including new planets.

This is called the conservation of angular momentum, and is often illustrated with the analogy of a twirling figure skater whose rate of spin changes when he or she extends or retracts arms or a leg.

This is a considerable inclination when one recognizes that the Moon possesses 82.9 % of the angular momentum of the Earth - Moon system.

The wheels work a lot like gyroscopes: When a reaction wheel turns, the spacecraft counter-rotates according to the law of conservation of angular momentum.

When Bailin deduced the angular momentum of the warped portion of the Milky Way's disk and compared that measure with SagDEG's angular momentum, he found that, within the margins of measurement error, the two angular momenta are very similar in strength and direction.

When you exceed the torque able to be produced by the engine by releasing the clutch too fast the engine will slow related to the difference in torque applied versus produced and the angular momentum of the system.

Because contraction of the vortex tends to require faster rotation (conservation of angular momentum), which increases centrifugal acceleration, which opposes contraction, it becomes hard for air to flow in sideways to take the space of warmer air that is rising when the air is spinning; thus, a rising column of air can pull up on air from below.

Re my: (solar or lunar - driven precession itself can't (approximately) happen at those times when the sun or moon cross the equatorial plane)... refering specifically to the component of precession that is wobbling of the Earth's angular momentum vector in an inertial reference frame; another component comes from shifting of the semimajor axis.

4) I say that when air moves from a location with high rotational velocity (m / s following a circumference) to a location with a low angular velocity, the air will conserve angular momentum and hence be diverted at right angles to the the initial impetus, resulting (at the poles) in a vortex around the pole.

When angular momentum is transferred the energy of the moon increases slightly, while the rotational energy of the Earth decreases much more, because the ratio of energy to angular momentum is inversely proportional to the effective radius of movement, which is much larger for the orbit of the moon than it's for the Earth.

When the flows within the core, oceans or atmosphere are modified in the transfer of angular momentum from the mantle, the energy may be stored in other collective motion.

Perhaps when the normal peak of the solar cycle lines up with the highest angular momentum from Jupiter and Saturn, then the solar activity is very high.

Could you please explain to me how to identify when Angular Momentum is at its highest and when the sun goes into Grand Minima using this solar motion application?

An example of this principle occurs when a skater pulls his or her arms inward during a spin (changing the mass distribution to one nearer the rotation axis, reducing the «moment of inertia,» and speeds up (increasing the skater's spin); because the moment of inertia goes down, the spin rate must increase to keep the total angular momentum of the system unchanged.

If and when you prove that there is no statistical correlation between Earth's climate and the 934 - year and 60 - year cycles that are obvious in the inverted plot of the scalar sum of the angular momentum of the Sun and all the planets then your argument might hold water — but not until you do prove such.

(I'm speaking here of ordinary momentum; angular momentum is simply the sum over all parcels of air of their respective ordinary momenta when constrained to move in a circle.)

When volumes 1 and 2 exchange locations we assume that each retains its initial angular momentum until most of the transition has happened.

``... this background modulation is very important when considering angular momentum and its effects of solar cycle modulation..»

In a vortex, turbulence is inhibited because when a particle of air moves inward, its tangential velocity increases to conserve angular momentum.
