Currently, if you weigh about 150 pounds in the Arctic Circle, you might weigh 149 pounds at the equator. That’s because of the extra centrifugal force that’s generated as the equator spins faster combats gravity. Press fast-forward on that, and your weight would drop even further. ...
This article discusses research on the Earth's core, with reference to a study led by J. Zhang, which appeared in the August 26, 2005 issue of the journal Science. The idea that the Earth's so...
They say the planet sometimes spins milliseconds faster or slower.A millisecond is a teeny, tiny bit of time. It is just 0.001 seconds. It takes 1,000 milliseconds to make up one whole second. Sometimes, the Earth’s spin may be about a millisecond — or even less — off its usual ...
(Imagine a basketball spinning on your finger. A random point on the ball's equator has farther to go in a single spin as a point near your finger. Thus, the point on the equator is moving faster.) 5. The planet moves around the sun (Image credit: Getty Images) The Earth isn't ...
The sun's magnetic field is typically only about twice as strong as Earth's magnetic field. However, it becomes highly concentrated in small areas, reaching up to 3,000 times stronger than usual. These kinks and twists in the magnetic field develop because the sun spins more rapidly at the...
As it collapsed further, the spinning got faster, much as an ice skater spins faster when he pulls his arms to his sides during a spin.Much of the cloud’s mass migrated to its center but the rest of the material flattened out in an enormous disk, as shown in Figure below. The disk...
What if Earth moved a bit faster or slower along its orbit or if it rotated at a different speed? What would our calendar look like then? Leap Sol Well, let’s have a look atMars. After all, this is a very Earth-like planet in our solar system and a likely candidate, at some ...
It is a seemingly tiring procedure, but skilled operators can transmit and receive faster than most secretaries can type.Morse telegraphy may seem weird and out of fashion, with its brass sounder and key operated by the world’s most basic tool, the human finger. However, it is sometimes ...
The work described here solves the challenge of needing a controlled discharge that is faster than 1/T1 but slow enough to be adiabatic to the spins. We note that a third approach, damped-oscillatory turn-off, has been described [8]; this is not appropriate here as it requires the ...
This is essentially the “slowest” possible turning time for the ship, and most turns will be much faster, a fraction of this time. When the enemy targets parts of your ship away from your center of mass, you can dodge simply by spinning along one axis. This particular ship is spinning...
