    Famous astronaut: - Aliens are visiting us?

    I don't think it's really possible for aliens to do as we think... come to earth, leave come to Earth leave, for that to be possible they would have to be relatively close :/ and from probes space shuttles lander's we haven't seen any of this sure there was and is water on Mars (frozen) but...

    Solving a Frictionless Bug Problem in a Bowl

    Homework Statement A bug slides back and forth in a bowl 11cm deep, the bowl is frictionless except a 1.5cm patch at the *flat* bottom coefficient of friction = .61 Homework Equations W = f*d r= 11cm \mu=.61 stickypatch=1.5cm The Attempt at a Solution i can get the first part (its...

    Calculating Total Kinetic Energy After Explosion

    Homework Statement Find the total kinetic energy in the system. a explosion fires two pieces both 7.3m high and 11.2m horizontally total kinetic energy done by the explosion the first piece is 15kg, the second 26kg? Homework Equations kinematics Ke=1/2(mv2) The Attempt at a...

    Multiple Integrals: What They Do & How to Understand Them

    I'm just curious of what exactly multiple integrals are for example if you have \int^{3}_{1}xdx you get 3-1[i think - it's been a while] but what does the second integral or 3rd and so on do to the function, I've looked ahead in my solutions manual and i think i understand part of it :D but...

    How Much Kinetic Energy Does a Ball Gain When Air Resistance Is Considered?

    i agree that it should be C because the air resistance would restrict it from gaining the full kinetic energy from it's potential energy.

    Centrepetal Force & Inclined Plane

    Homework Statement I Have two questions one of them i just can't start it, I don't understand what it is I'm supposed to set up or how. A Block is shoved up a 22 degree slope with an initial velocity of 1.4 m/s the coefficient of friction is .70 how far up the slope will the block make it...

    THE QUESTION: WHO OWNS THE FISH?

    Yes, but its obvious your assuming the missing pet is a fish ^.^ I will attempt to solve it in chemistry :) I think that some information may be irrelevant in how it is given. i have however come up with this

    Implicit Differentiation Check

    Homework Statement just a check, in Implicit Differentiation if you have let's say (x2+y2)2 would you get 2(x2+y2)(2x+2y(dy/dx)) or would it go out of the whole function in the chain rule and be 2(x2+y2)(2x+2y)(dy/dx) much appreciated.

    Calculators How do the mrc m- and m+ buttons work on a very basic calculator?

    Me either, probably because i don't even know what they are exactly for :/ and on a basic calculator? must have some use to normal math i suppose.

    Could a Supermassive Black Hole Destroy Our Galaxy?

    Thanks :) I'll check it out. Edit: :) Thank you again, that answered pretty much everything. Edit2: Could that be why our galaxy is a spiral galaxy? our galaxy is moving right --?

    December 21st: Is the Mayan Calendar Really Right?

    What do you think is REALLY going to happen? are the mayans right about the end of the calander? or is this just a far fetched theory. Personally, I think the worst thing that could ever happen is the reversal of Earth's North and South poles knowing that this is well over due. The end of the...

    Physics riddle (relocate if necessary)

    Question, i understand why thing's can't travel at the speed of light, It's clearly obvious but the "Nothing with mass can" why doesn't light have a mass, i mean it does succumb to extremely high gravitational energy like a black hole right or is this caused from something else?

    The Big Bang: Where Did it Come From & Does Time Exist?

    Time clearly existed before us we didn't "invent" it. but, time can't just have been the creation of the universe that doesn't make sense for that to be true time just would have begun at one random point in... what? I mean time had to exist before the universe began for this to be true, but how...

    Could a Supermassive Black Hole Destroy Our Galaxy?

    That is what i meant ^.^ makes sense i guess. i understand that there can be black hole sattelites, is there any reason that there are black holes at the center of the galaxy's? or is it just simply because of the power galaxy's have as they are beginning to form. Because from how i...

    Giant list of science fair project ideas

    for my grade-8 science fair i did "The Brain & Optical Illusion Effects" i got 100% :D wasn't to hard to get the info for it, talk a little about the brain and why our eyes can be deceived then write down a giant binder with 50+ Optical illusions and how they are caused ^.^
