Then Kaku states that force fields can do more than deflecting laser beams because it can levitate objects by the use of magnetic force fields. To support that, he explains that when we place two magnets opposite to each other, the two magnets will repel each other. However he wrote that making force fields and to levitate heavy objects is nearly impossible since we lack advanced technology. For my response, Kaku doesn’t completely explain everything. 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.
One of the greatest advantages of nuclear power is that it avoids the wide variety of environmental problems arising from burning fossil fuels such as coal, gas and oil. Currently 78% of Australia’s electricity comes from burning coal. Nuclear energy does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect. Thus ‘global
Anaximander, who was a student of Thales, argued that the four elements, water, air, earth, and fire can change into one another and therefore none of those elements could be the principle element, the Arche. Anaximander’s Arche was something he called Aperion. Aperion, he claimed, was an infinite, boundless substance that all of the elements were derived from and that things can into being by necessity. Anaximander was also very interested in astronomy. From his observations, Anaximander concluded that the sun was nothing more than a disk with hot gas escaping out of it, and that the stars were holes in the sky where light shined through.
Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed. Electric force – Is the attraction or repulsion of particles or objects because of their electric charge it is one of the basic physical forces. Magnetic force – Is the attraction or repulsion that arises between electrically charged particles because of their motion; the basic force responsible for the action of electric motors and the attraction of magnets for iron.

The hypothesis was that liquids will not weaken the magnetism of magnets because only magnetic materials block magnetic fields. This hypothesis was proven in the project because the numbers only increased in very small numbers. Therefore, liquids have a very little effect on magnetic
These potential causes can be grouped together to be dismissed, having a similar end result. Nuclear war and the less likely, but still possible, gamma ray burst can be easily dismissed due to the lack of one key condition. A gamma ray burst is a type of explosion caused by a star nearing supernova. Its explosion sends a massive amount of radiation and energy in a very compact beam that could easily bake the planet with enough radiation that nearly all forms of complex life, humans included, would perish quickly. The resulting nuclear winter would occur causing the aforementioned minor ice age event, but it is the lack of radiation that prevents this from being a possible answer.
Being that they were in space there is no air in the moon’s atmosphere thus a flag waving is impossible. 2. Multiple light sources. When on the moon the sun is the only light source therefore all shadows should run parallel to one another. This was not the case, in various videos and pictures from the landing, shadows are clearly seen in many different directions.
The surface of Mercury and the moon share similar physical characteristics but also differ in certain aspects as well, outlining variations in their respective geological histories. In general, both the moon and Mercury show great similarity in size and from their substantial amount of craters which can be attributed to their lack of a prominent atmosphere that would burn up any primordial impacts. However, a closer look shows many differences. For example, the moon has 14 maria (lava flow regions), a relatively large number when compared with Mercury as it has few maria. This gives us a hint as to how fast Mercury and the moon cooled in relation to each other, as the cooler planet would
The basic force of the universe The force of attraction between all objects in the universe A force we experience all the time All of the above | | 2. | An object's weight: Depends on the strength of the force of gravity Would be the same everywhere in the universe Has nothing to do with gravity | | 3. | The amount of gravity between two objects depends on: The distance of each object from each
What happens to the waste? For example, nuclear energy does not produce smoke or carbon dioxide so it does not contribute to air pollution. (Technology Student ,2009) Nuclear power is characterized by the very large amount of energy available from a very small amount of fuel. The amount of waste is also relatively small. However, much of the waste is radioactive and therefore must be carefully managed as hazardous waste.
