    What are the disadvantages of traveling into the future?

    In any persuasive essay, its important to bring up the opposing viewpoint. Talk about something good, like curing yourself with a future medicine, or enjoying the advanced technology of the future. Then say why its wrong. By doing this, you show your audience that you know what you're talking...

    What are the disadvantages of traveling into the future?

    A problem would be coming back and expecting things to happen the way you saw them in the future.the problem is you're asking for a scientific answer to a very unscientific question. You might want to check out the new book "The Physics of the Impossible" by Michio Kaku, where he talks about the...

    Testing Deciding Between the ACT and SAT: What's the Difference?

    I'm not sure what you mean. Dyslexia is a handicap, and there are modifications made to the test environment to make is more fair. I'm not too sure about this process. With the IQ of 150, you might have an advantage. Although my friends in prestigious colleges (Berkeley, for example) did worse...

    Testing Deciding Between the ACT and SAT: What's the Difference?

    Firstly, a genius with a 150 IQ who does not study will not do well on the test. Intelligence is also a measure of how well one applies oneself. Secondly, while the other parts of the test might not be as important as your major subjects (say math and physics) they are still necessary. You'll...

    Linear Velocity and Acceleration

    This wikimedia photo might help conceptually This is if there is no angular acceleration. That is, tangential velocity is constant and nonzero.

    Linear Velocity and Acceleration

    There is only tangential acceleration if the rotation is speeding up (if there is radial acceleration). However there is always centripetal acceleration if an object is rotating. You can imagine that as a string holding a ball being swung around. The centripetal acceleration is keeping the ball...

    Testing Deciding Between the ACT and SAT: What's the Difference?

    The SAT and ACT cover a huge amount of criteria, I agree. But if you suck at math, and you're applying to an art school, or music, then you're fine! Maybe the cream of the crop of schools (ivy league, etc) might reject you because you do badly on that part of the test, but generally schools...

    Testing Deciding Between the ACT and SAT: What's the Difference?

    There's a lot of art in Physics. In fact, it was Feynman that said that an artist claims he can see beauty in a rose that a scientist cannot, but a scientist can understand the amazing patterns and complexity of processes required for there to be a rose, and therefor has a better understanding...

    Position as a function of time

    A couple of questions: what do you mean by "Time is increasing from 0.0 to 2.0 by .1" Do you need the equation for after the force is applied, or just while the force is applied? Also, what have you tried doing so far? We can only help you if you show a sincere effort in solving the...

    Amazing Physics Demonstration - Unravelling the Mystery

    Superconductivity just means "zero resistance" and no interior magnetic field. Only certain materials can do this, and only at very very low temperatures, close to absolute zero. The reason the magnet levitates is as Snazzy said. Basically, in order to keep the properties of a superconductor...

    Why Don't We Feel Earth's Movement and How Do Tides Affect Well Water Levels?

    Actually, I think this is not a true statement. The force of gravity from the moon felt by the center of mass of the cup, with the average force felt by every molecule in the cup, would negate each other. You could argue that water tension could allow for water to be closer to the moon, but...

    Rockets in Space: Need for Engines to Change Direction

    The quick answer: It is not pushing against the air. It is pushing against its own fuel! This is due to the conservation of momentum. Imagine you are on a frictionless ice rink with a big rock. (this is space... no air resistance = frictionless) Now, if you throw the rock to the west, you will...

    What Energy or Frequency Affects Electronic Appliances?

    Federal Communications Commission You'll often see on any digital apparatus a quote from Part 15 of the FCC rules: "(1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation." I think...

    Why Don't We Feel Earth's Movement and How Do Tides Affect Well Water Levels?

    The Earth travels 2.5 millions kilometers every day. Thats more than a hundred thousand km/hr. Now, if you were on the equator, your speed, relative to the center of the Earth (not counting the hundred thousand miles we're already going at) is 1670km/hr. You can imagine, then, that, disregarding...
