We can have a uniform gravitic field \(k_0\), just like in a particle accelerator a uniform magnetic field can hold high-speed particles in an orbit. Unlike \(\vec {g}\) field (and electric \(\vec {E}\) field), the mathematical expression of \(\vec {k}\) field (like magnetic...
Talk about how this star's massive gravitational pull draws the planets toward it, even though they never fall into the sun. Bodies in a solar system remain in orbit because of their motion around their star. If the sun disappeared suddenly, Earth and the other planets would fly off into ...
Space is generally defined as starting at about 100km (60 miles) above Earth (an arbitrary point sometimes called the Kármán line), which is where conventional planes would struggle to make enough lift to stay in the air. That doesn't mean Earth's atmosphere is all done and dusted by ...
The six words are: "It works in Kerbal Space Program". Oberth maneuvers[edit]The Kuiper Belt is a region of the outer Solar System beyond the orbit of Neptune consisting of numerous small icy bodies, including the dwarf planets Pluto and Eris. An Oberth maneuver is a spaceflight maneuver, ...
The basis of those models is the degree signature of a graphlet12. The graphlet degree signature is an extension of the node degree that quantifies the number of times a node in the network appears in an orbit (referred to as “touch an orbit”). Consequently, graphlets provide a ...
Centripetal force is the force acting on an object in curvilinear motion directed towards the axis of rotation or the centre of curvature. "Any satellite placed near Lagrange point L1 would move in harmony with the Earth's orbit around the Sun, providing uninterrupted observations of ...
Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have developed a new method for creating pairs of entangled photons, particles of light whose properties are interlinked in a very unusual way dictated by the rules of quantum physics. The...
This is known as the two-way shape-memory effect. Now what if you could make a shape-memory object that would bend and twist by a huge amount but still return perfectly to its original shape, even without heating? That's an aspect of shape memory called pseudo-elasticity or ...
Question 1 Any theory of the origin of the Solar System must explain all of these EXCEPT 1) the orbits of the planets are nearly circular, and in the same plane. 2) the direction that planets orbit the Sun is opposite to the Sun’s spin. 3) the terrestrial planets have higher density...
The sum and product rules of probability refer to methods of figuring out the probability of two events, given the probabilities of each event. The sum rule is for finding the probability of either of two events that cannot occur simultaneously.
