Ok this is a little awkward, but how do you explain chemically the action of cutting, why does it matter if something is sharp? How do elements interact chemically that make things cut or not, cuttable. Why are diamonds the best for cutting? Is cutting the result of a chemical reaction or does it cause a chemical reaction?

I have a need for a mechanically powered DC generator. When looking for vendors online most(or all) products are coupled with a motor. Since I'm looking to convert already existing rotational energy into electrical energy, I do not need the motor.

To anyone that has attended Pharmacy School, how hard is it compared to Pre-Pham classes, this probably various from school to school and which professors you have, but just in general. Are the classes about the same? Since most sciences build off of each other, Im thinking they might be about the same. What type of classes did you have to take? I know a lot of science stuff but specifically which type of chemistry and bio exc.

Im also curious as to what gpa you had when you got accepted into Pharmacy school, thanks

I use 4 mortar like cannons to propel a projectile. Attached to the projectile is a net. The net is shot over birds to trap and relocate them. The motive force for the projectiles is compressed air at 120psi. The air is discharged into the mortar barrels simultaneously. I've been told that if I lengthen the barrel, I will be able to obtain greater projectile velocity. What are the parameters that would control the velocity? How can I calculate the optimal barrel length? I'm thinking with a short barrel, a lot of the compressed air escapes from the end of the barrel as the projectile leaves. Thus energy wasted. It seems like the optimal barrel length would be when the compressed air pressure has dropped to atmospheric pressure at the point at which the projectile exits the barrel. Assume a large tank feeds each mortar barrel and there is a negligible drop in pressure during the discharge. An electronically controlled orifice of diameter D opens for duration T.
