For 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
A. zero
B. minus 1
C. minus 2
D. minus 3
a) Sketch a generic HR diagram, including labels for the
axes. (Take a picture or scan your work and upload it as
a separate file.)
b) Consider the following three stars, place them on your
HR diagram and determine their rough spectral type and
class of star. Also calculate their size relative to the Sun.
I) L = 0.001 Lsun T = 3000~K
II) L = 20,000 Lsun T = 4000K
III) L = 0.001 Lsun T = 15,000K
For 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. Suppose that a certain radioIsotope could emit TWO alpha particles, and its product (daughter nucleus) could then emit ONE beta-minus particle. The atomic number of the resulting element would be changed by
A. zero
B. minus 1
C. minus 2
D. minus 3

Suppose that you are observing this star in the night sky without a telescope. Ignoring any interstellar extinction or atmospheric absorption, approximately how many photons per second arrive at your retina? Show all steps in your calculation. Look up any required information about the star using Wikipedia. Use sensible approximations so your calculation is straightforward. For example you could consider only the region of the spectrum where the photon flux peaks. b) The Mid-Infrared Instrument (MIRI, camera and spectrograph) on the James Webb Space Telescope operates in the band 5 – 28 µm. For 58 Eridani, approximately how many photons per second can be used by this instrument? Assume that MIRI takes all the photons from the full JWST mirror. Show all steps in your calculation. Describe briefly two or three other factors which play a role in determining the sensitivity of an instrument such as MIRI?arrow_forward

For the CR's, claim you should answer the question of , do you get 2 real solutions, 1 real solution, or 2 complex solutions? For your reasoning you should explain how you know. Use the example attached to help you answer. hints: that plus minus sign means there are two answers. If the number under the square root is positive, you have two real solutions. If the number is negative you have two complex solutions. If the number is 0 under the square root you have 1 real number solution.arrow_forwardUsing a Hertzsprung–Russell diagram to illustrate your answer, describe in detail the followingmain stages of a solar mass star’s evolutionary track.
