Is the soeed of an electron relativistic?

AI Thread Summary
The discussion focuses on determining whether the speed of an electron in a hydrogen atom is relativistic, given its circular orbit around a proton at a radius of 0.5 x 10^-10 m. The participant expresses uncertainty about the relevant equations and how to approach the problem, particularly regarding centripetal acceleration and velocity. They eventually indicate that they have solved the problem. The key takeaway is that an electron's speed in this context needs to be compared to the speed of light to assess its relativistic nature. The conclusion emphasizes the importance of understanding both classical and relativistic physics in such calculations.

Homework Statement


Determine the speed of an electron in a hydrogen atom (radius .5 * 10^-10 m) and state if it is relativistic. (Treat the electron as through it were in a circular orbit around the proton.) (Given that .1c and greater is relativistic)

Homework Equations


not sure...
L=L0 (1-v^2/c^2)^1/2
a=v^2/r
?

The Attempt at a Solution


I don't really know where to start. I assume the fact that the electron has a centripetal acceleration and velocity comes into play somehow.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
