No Worries, Thankyou!

For our last physics and chemistry project at Tully High, we broke the record for the Largest Nuclear Fission Model with mousetraps and ping pong balls! The record can be viewed via the following link

We have got a series of data points which form a hyperbola. Does anyone know any programs that can get the equation from our points using regression (hyperbola line of best fit). We need to find the equation for investigations with Michaelis-Menten

No, not at all. Physics is a hard subject to grasp and we are here to help. Start off with the mathematical model, and we'll see what you come up with.

At the start our project it was going to be with molasses but we changed it to HONEY after this post was made... SOme additional information we have come up with, any thoughts? Yield of ethanol is mostly about survivability of the yeast. Yeast can't survive too high concentrations of sugars...

Don't worry about the above post, we have refined it down to this explanation, not sure if it is entirely correct, Alcohol denatures proteins by disrupting the side chain intramolecular hydrogen bonding. New hydrogen bonds are formed instead between the new alcohol molecule and the protein side...

Here are some notes we gathered, does any of it make sense. Or is any of it a reasonable explanation? A 62% ethanol solution is used as a disinfectant on the skin. This concentration of alcohol is able to penetrate the bacterial cell wall and denature the proteins and enzymes inside of the...

Yield of ethanol is mostly about survivability of the yeast. We were wondering why Yeast can't survive too high concentrations of ethanol? Something to do with the denaturation of proteins? Not really sure on this, any help is appreciated Thanks

It means that 9.10938291 have all been confirmed the right values, and its a prediction that the next 2 numbers are 4 and 0 Thanks, Z.c

The speed of an electron will approach but never reach the speed of light (c). The definition of the speed of an electron in a wire, is current. So unless the current of a given device to use your example, a flashlight, is moving at a speed of 299792458m/s it is not exceeding the speed of...

Yes, Thanks, DDZ

EMF refers to voltage generated by a battery or by the magnetic force according to Faraday's Law, which states that a time varying magnetic field will induce an electric current. Electromotive "force" is not a force (measured in Newtons) but a potential, or energy per unit of charge, measured...

The scales measure the objects weight, because when you place the object on the scales it is influenced by the gravitational pull. Weight=mg therefore to get the mass, you must divide 9.81 Thanks Z.C

Here are some ideas that might get you going, -Mentos in coke, measuring the height of the eruption, working out the energy contained by the mentos, repeat with varying masses of mentos, remembering to keep variables such as the amount of coke constant and temperature. -You can also try...

I have to tell you Da Apprentice:, you have asked a very complicated, multi-part question. It will be a lot of work for us to answer all parts. And our forum rules still apply, you have to do most of the work.
