Homework Answers
An electron in the atom keeps on revolving around the nucleus along fixed parths known as orbits.
This circular motion of electron around the nucleus is due to the centripetal force balancing the the electrostatic attractive force between electron and nucleus. This centripetal force actually produces an acceleration known as centripetal acceleration. the centripetal force is actually very necessary for the atom to be stable and electron to be keep on moving in fixed orbits around the nucleus because if the centripetal force wouldn't have been there then the electron would have simply collapse into the nucleus due to its attractive electrostatic force.

Also in the hydrogen atom, what is the force exerted by the electron on the proton?...
Also in the hydrogen atom, what is the force exerted by the electron on the proton? If you get the same magnitude for the force as in question 1, could you then conclude (by Newton’s Second Law) that the proton and electron experience the same (centripetal) acceleration magnitude? Why or why not

Part a. An electron is moving in an atom at a velocity of 2 x 10 m/s. Suppose we measure the electrols position as being 5.00 x 10-10 m from the nucleus with an uncertainty of 1% (a) Calculate the uncertainty in the velocity of the electron? (b) Calculate the percentage ratio of the uncertainty in velocity relative to he velocity of the electron: (uncertainty in velocity)/(velocity) x 100%.

A UFO going 1 m/s east suddenly experienced a constant acceleration during which it's displacement was 8,363.5 m east and was going 388 m/s east at the end of said acceleration. Determine the magnitude of the UFO's acceleration & how long the UFO was accelerating.

A hydrogen atom that has an electron in the n=1state absorbs a photon. What wavelength must the photon possess to send the electron to the n=4 state? wavelength: nm What possible wavelengths would be detected in the spectral lines that result from the deexcitation of the atom as it returns from n=4\ to the ground state? Classify each wavelength as either possible or not possible. Answer Bank: 821nm 656nm 1460nm 103nm 365nm 122nm 486nm 1880nm 91.2nm 97.3nm Possible: Not possible:

When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced, the electron slows down in the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy E_r of a photon of radiated light. E = K - K', where K and K' are the kinetic energies of the electron before and...

The quantum mechanics states that there is not any interaction between an accelerating electron and atoms in a perfect crystal. So all of the free electrons should accelerate as long as the electric field is applied, which would cause an electric current that is continuously increasing with time. But as you know, a current reaches a constant value. Explain why.
