When a roller coaster car is at the bottom of the hill, it has 100% kinetic energy.

Label this question as Q-Wave on your paper. (8 min.) For this problem, you must show your work exactly as shown in the PPT lecture videos.  You must include the starting equations, starting variables, use correct sig figs, and circle your final answers on your paper.  You must state your final answers here on the exam with units.  Failure to follow these directions will result in significant to total point loss.  You must upload your work to the Canvas dropbox as directed in the exam directions. Consider a photon with an energy of 6.997 x 10-19 J. A)  What is the frequency of this photon in SI units? B)  What is the wavelength of this photon in nm? c = 3.00 x 108m/s; h = 6.6262 x 10-34 J s; 1 m = 1 x 109 nm State final answers here with the appropriate letter.
