At what velocity does a proton have a 6.0-fm wavelength (about the size of a nucleus)? Give your answer in units of c.
In extreme-temperature environments, such as those existing in a solar corona, atoms may be ionized by undergoing collisions with other atoms. One example of such ionization in the solar corona is the presence of C5+ ions, detected in the Fraunhofer spectrum. (a) By what factor do the energies of the C5+ ion scale compare to the energy spectrum of a hydrogen atom? (b) What is the wavelength of the first line in the Paschen series of C5+ ? (c) In what part of the spectrum are these lines located?
Assuming that the radius of the circular path of the electron is 4.9cm when voltage is 100v and coil current is 1A and The Helmholtz coils have 130 turns and a radius of 15 cm. With N=130 and R=0.15 What is the velocity of the electrons at 100 V, assuming the known charge and mass of the electron from the accepted universal constants that are the basis of SI units? Hints: Do a classical calculation of the kinetic of the electon assuming you know its mass (in kg) and its charge (in coulomb). That will be 1/2 mv2. Equate that to the energy of the electron gained by accelerating in the electric field, that is, eV where "e" is the charge and "V" is the difference potential in volts. Solve for "v", the velocity. Enter your answer in km/s, 103 m/s, without units. It is best to enter only a number, without an "e". For example, if you found 2000 m/s you would enter "2" for the velocity in km/s. Electrons have low mass and achieve high velocity in modest fields.

Suppose that you have 1 mol of hydrogen atoms in the ground state. If the atoms are irradiated with light, what is the minimum number of photons required to excite all of them?

You are studying a very distant quasar and are trying to determine how far away it is. The quasar is a very bright point-like light source, and there is only one relevant distance measuring technique applicable to objects at such a great distance. From a spectra of the quasar, you observe that it's Lyman alpha emission line (which would be at 121.6 nm in a laboratory sample of Hydrogen) is at 130 nm. What is the distance to this quasar in units of Mpc. [Hint: Think about what distance measuring technique we use for the very farthest objects in the universe. You will need to look up a special constant (who's value is uncertain) to complete this problem. The answer accounts for the possible range of uncertainty in the quantity you need to look up.]
