Multiple-choice questions may continue on the next column or page – find all choices before answering. 001(part1of3)10.0points The following questions refer to the hydrogen atom. What is the minimum kinetic energy in electron volts that an electron must have to be able to ionize a hydrogen atom that is in its ground state (that is, remove the electron from being bound to the proton)? The picture below shows the spectrum gath- ered when light is passed through a gas of a certain element. Explanation: There will be three absorbed photons with energies 10.2 eV, 12.09 eV, and 12.75 eV. 004 10.0points What do the dark vertical bands indicate?
002(part2of3)10.0points If electrons of energy 12 . 8 eV are incident on a gas of hydrogen atoms in their ground state, photons can be emitted by the excited gas. How many different photon energies could you possibly observe? Wavelengths of light that got scattered away at some angle 003(part3of3)10.0points 1. Wavelengths of light that got scattered away at some angle
If instead of electrons, photons of all energies between zero and 12 . 8 eV are incident on a gas of hydrogen atoms in the ground state, how many different photon energies are there at which the photons can be absorbed? Assume single absorption. 005 10.0points A bicycle wheel has a diameter of 81 . 7 cm and a mass of 0 . 906 kg. The bicycle is placed on a stationary stand on rollers and a resistive force of 67 N is applied to the rim of the tire. Assume all the mass of the wheel is concentrated on the outside radius.
