7.
The second brightest star in the sky (after Sirius) is Canopus. This yellow-white supergiant is about
1.13616 x 1016 kilometers away. How far away is it in light years?
28.1
8* Regulus (one of the stars in the constellation Leo the Lion) is about 350 times brighter than the sun. It is 85
light years away from the earth. How far is this in kilometers?
9. The distance from earth to Pluto is about 28.61 AU from the earth. Remember that an AU = 1.496 x 108 km.
How many kilometers is it from Pluto to the earth?
10. If you were to travel in a straight line from Los Angeles to New York City, you would travel 3,940
kilometers. How far is this in AU's?
11. Challenge: How many AU's are equivalent to one light year?
Please answer each and every question. Please double check your work and DO NOT SKIP ANY STEPS! Include appropriate notes next to each formula and make sure to include allllll work. Thank you!

- ONLY ANSWER 3 AND USE OTHER QUESTIONS FOR CONTEXT Suppose we have two sources of light, a deep red one with wavelength 700 nm, and a violet one with wavelength 400 nm. Both produce the same optical power, delivering 1 milliwatt (10−310−3 watts) of energy per second per square centimeter to a metal target with an area of 1cm2 located 1 meter from the sources. 1. Which color would deliver more photons each second? All the photoelectrons that are produced from the light are presumed to be collected by another electrode and we determine the current in amperes using a circuit and an "ammeter", that is, some device that can give a precise quantitative measure of the current. Such a device might use the magnetic field generated by the current, or the voltage produced when the current flows across a resistance. 2. If the work function of the surface is 2 eV, will we see a current with both colors, one color, or neither one? If so, how much (in amperes), or if not, explain. 3.

- Show your work is what's required.arrow_forwardFor this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha, Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. A certain radio-isotope emits ONE alpha particle, and its products then emit TWO beta-minus particles in succession. The atomic number of the final resulting nucleus will now change (as compared to your starting nucleus) by O A. zero O B. minus 1 OC. minus 2 O D. minus 3arrow_forwardONLY NEED ANSWERS TO D&E!!!
