Suppose that you have a structure on a planet or a spaceship in the middle of nowhere, and suppose you don't want the force field on all the time either because there are times when protection isn't needed. The outer layer of your force field is hot plasma (hot gas of ion). Where are these ions when the force field is off and how long does it take to turn it back on? The middle layer is the group of laser beams. When the force field is off, do the laser beams stay outside the nanotube layer?
Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle. 6. A pulsar does not pulse, it emits beams of radiation that sweep around the sky as the neutron star rotates, and astronomers detect pulses when they sweep over the Earth. 11. Sometimes in binary systems, mass flows into a hot accretion disk around the neutron star and causes the emission of x rays.
This field, given by g=GMr2, (where g is the acceleration due to gravity or the gravitational field strength, G is he universal gravitational constant, M is the mass and r is the radius of the planet) acts on objects both on Earth and around it. g varies because the Earth is not a perfect sphere. * Explain that a change in gravitational potential energy is related to work done. * Gravitational potential energy is the energy of a mass due to its position within a gravitational field. When work is done on an object there is a corresponding change in kinetic and/or potential energy of the object.
The live guitar is amplified to blend well with the backing tape. Texture. Electric Counterpoint starts with a sparse texture however the piece is mostly contrapuntal. The texture is built up as more guitar parts are brought in and is gradually thinned towards the end as parts drop out. Interweaving rhythms give the impression of a changing texture.
Isotopes Lab By: Darlene Cortez (1st Pd) Background: Atoms of the same element that have different masses are known as isotopes. The difference in mass between isotopes is the result of these atoms having different numbers of neutrons. Key vocabulary: Relative abundance- Relative abundance is a component of biodiversity and refers to how common or rare a species is relative to other species in a defined location or community. Weighted average - An average that takes into account the proportional relevance of each component, rather than treating each component equally. Average Atomic Mass- The mass calculated by summing the masses of an elements isotopes, each multiplied by its natural abundance on earth Mass Number- The total
The static magnetic field exerts a magnetic force that can dislodge the pacemaker leads. On a brighter note the more modern up to date pacemakers are smaller and have less moving parts. They have leads that are less susceptible to the magnetic force and have a lower risk factor of being moved. (Ahmed, et al., 2013) The radiofrequency field effects the pacemaker differently than the static magnetic field. It can actually heat the lead used in the older models.
The element used in atomic bombs is Uranium-235. Uranium's atoms are unusually large, and henceforth, it is hard for them to hold together firmly. This makes Uranium-235 an exceptional candidate for nuclear fission. Uranium is a heavy metal and has many more neutrons than protons. This does not enhance their capacity to split, but it does have an important bearing on their capacity to facilitate an explosion.
In addition, entering a black hole would not only take thousands of years to occur, according to “Spaghetti theory” the gravity would be so intense as you neared the center of the black hole, your body would be stretched out into a thin strip of organic matter. Not to mention that this is all assuming that black holes are connected to other black holes in some separate universe and at a different time. Speaking of which, since time is relative, Spock going into the black hole a few seconds after The Narada, and coming out after it has been 25 years is quite plausible. So both the timeframe and how this scene was portrayed have little scientific background and is most likely
In the absence of a force both the amount and direction of momentum will not change. When two objects with a particular angular moment relative to a common fixed point interact they affect each others angular momentum and the total angular momentum is conserved. When you consider an orbit, the angular momentum is distributed between the spin of the planet itself and the angular momentum of its orbit, but, if a planet is found to spin more slowly than expected, astronomers suspect that the planet has a satellite, since the total angular momentum is shared between the planet and its satellite for the sake of conservation. Some scientists believe that large impacts in the early history of the Solar System may have affected the rotation of some planets. One may have caused Venus to rotate in retrograde and another could account for the 23 degree axial tilt of the Earth.
The element with the largest number of stable isotopes found in nature is tin, which has ten stable isotopes. All elements also have unstable isotopes, which are more susceptible to breaking down, or decaying, than are the other isotopes of an element. When atoms decay, the number of protons in their nucleus changes. Since the number of protons in the nucleus of an atom determines what element that atom belongs to, this decay changes one element into another. Different isotopes decay at different rates.
