U-235 undergoes fission with slow neutrons,these join the nucleus of U-238 to form neptunium,which in turn decays by beta emission to form uranium.But I want to know if neptunium is found as a stand alone element in nature.

Could I still be a good, well-respected surgeon, even if I'm from Indiana? Because supposedly, people from Indiana are "dumb"... v.v Like, are there any famous or well-known, good surgeons from Indiana that I could see as a role-model? And does Indiana have alot of surgeons? Or is it like the least likely place to produce surgeons. I mean, like, are the LEAST amount of surgeons from Indiana? Or are there alot of surgeone in Indiana? I'm really paranoid that because I'm from Indiana, I won't make a good surgeon...

atoms have electrons(negative) and protons(positive)...and they said that opposite attracts each other. The nucleus of an atom contains protons. The electrons now orbit around the nucleus? why is it like that? why isn't the electron attracted by the nucleus eh it contains the protons?

example 1 : If someone is on a school bus travelling at 60 MPH, and then she gets up and walks forward, her speed is 1 MPH, how do you record the speed of the person?

Is her speed 60 mph, 61 mph or should you list it at both velocities : 60 mph + 1 mph.

My thought on this is that speed is relative. Someone on the bus observes her travelling at 1 mph, but someone off the bus observes her at 61 mph (I'm assuming). To account for this you record the speed at 60 +1 mph so that someone looking at the record sees there are two different velocities.

Second example: Someone is travelling in a car and fires a gun that is perfectly perpendicular to their forward direction.

Not accounting for any wind resistance, will the bullet continue to move in the direction of the car?

My guess is that bullets leaving this moving object would form a diagonal (triangle with direction of car, intended direction of bullet and actual direction of bullet. Thoughts from physics students?
