take a cunductive wire. coil it (for conventional space) then run electrons through it with 8.98755179 × 10^16 J (the same number for the speed of light squared) of energy. ( i realize that doing that is nearly or completely impossible). using the equation m=e/c^2 e and c^2 are the same...
so follow me on this one. motion has energy ... energy is in the form of waves ... correct? there are such things as destructive waves. so what if you found the exact wave of a moving object and sent destructive waves at it. could you at least slow it down? perhaps by using the air around...
i've got thoughts about a series of chemical reactions that would simply keep on repeating. perhaps by time release. the thought is to use this perpetual chemical reaction to create a battery that releases the electrons then has a series of chemical reactions eventually resulting in the two...
I studied calorimetery in physics, but reflecting upon old equations i can't seem to find one that will tell me how long it takes to change the temerature of the substance. I'm mainly looking for how fast water will change temperature. I'm guessing that the rate in which it changes depends on...
Homework Statement
the problem has height in cm, and density in g/cm^3. do i have to convert the gravity into cm/sec^2?
see below:
Homework Equations
pressure=(height in cm)(density in g/cm^3)(gravity in m or in cm?)
The Attempt at a Solution
if you mixed water with a feromagnetic metal and then ran it through permanent magnets (giving it a charge or allign it correctly) , then heated it up into stem and ran it through a coil of copper wire (in some way as to cause electrons to flow). waited for it to condensate (perhaps using the...
yes but when the water flashes into stem all it is doing is pushing on the tin. as a result the tin pops out. when it pops out it loses force to the water being expelled. right?
say you have a force generating object such as a rocket. this force generating object suddenly gains mass (avoiding the inelastic collision part). the rocket itself is creating a constant force. but now its got this mass. what is the new force of the entire thing?declining frictional loss...
the pivot point does have a mass. k^2 you sound spot on. yet i fail to fully understand what you are saying clearly. would you please mind explianing it more?
as you all know the equation for centripetal force is (m((2 pie r)/t)^2)/r). ok so imagine this. a weight attached to a string attached to a pivot point. the weight is rotating around the pivot point. the pivot point can move back and forth along the x axis. if looking at a x, y graph. the pivot...
