#### Question 1 1. If an orange luminescent comet in outer space is able to move at a velocity faster than the speed of light (due to a cosmic explosion) away from an observer who is located on a nearby planet, which color would the observer most likely view emanating from the comet?

#### Question 2 2. If white light is shone normal through a single slit whose opening is 470 nanometers wide, what color of the visible light spectrum is least likely to exhibit diffraction as it passes through the slit?

#### Question 3 3. Which of the following sampling techniques would be the most efficient method to utilize to obtain data to support the hypothesis ''In the Eastern United States, trees with heights greater than 50 feet tall are normally an oak species?''

#### Question 4 4. One atom of the element Bismuth-209 (atomic mass = 208.9803987 atomic mass units) undergoes a radioactive decay reaction to form one thallium-205 atom (atomic mass = 204.9744275 atomic mass units) and one alpha particle (atomic mass of 4.001506 atomic mass units).
