7. One way to analyze E MR is to pass the radiation through a prism or a diffraction grating. This causes the radiation to separate into its component wavelengths, producing a spectrum. Depending upon the
source, three types of spectra can be observed. For each of the following types of spectra, describe a possible source and indicate how this information could be used by astronomers.
a. continuous spectrum
b. absorption spectrum (dark-line spectrum)
6c) emission spectrum(bright-line spectrum)
8. Sketch a series of diagrams to show the main steps in the evolution of stars like the Sun.

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34Ã10â27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 Ξa how many deuterons strike the target each second?
