Ps. Please answer on paper Thank you!
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
O A. zero
O B. minus 1
OC. minus 2
O D. minus 3
Read the following questions carefully and answer the problems using GRESA.
1. Assuming that the field of view is flat, what is the resultant vector (yellow line) of an observer pointing his telescope starting at the Andromeda galaxy, then moving 62 units 27° S of W to Jupiter, then finally moving to Saturn 17 units 72° S of W. Express your magnitude to the nearest hundredths units, and the angle to the nearest hundredths °, following the standard cartesian plane coordinate system.
