Chapter 9, Problem 13SEQ
Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk(*) designates a quantitative problem, for which you should show all your work.
Homes to Civilization? We do not yet know how many stars have Earth like planets, nor do we know the likelihood that such planets harbor advanced civilizations like our own. However, some stars can probably be ruled out as candidates for advanced civilizations. For example, given that it look a few billion years for humans to evolve on Earth, it seems unlikely that advanced life would have had time to evolve around a star that is only a few million years old. For each of the following stars, decide whether you think it is possible that it could harbor an advanced civilization. Explain your reasoning in one or two paragraphs.
a. A
b. A
C. A
d. A
e. A red supergiant

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
PROBLEM SOLVING: Express your answer to the fourth decimal places. Show complete solution.
Box your final answer.
1. A wooden object found in an Indian burial ground and subjected to radiocarbon dating.
The decay rate associated with C-14 is 10 disintegrations per minute per gram carbon.
What is the gge of the obiect?
Read each problem carefully. Solve each quadratic equation for the variable(s) specified.
Be sure to show all of your work. Explain in two to three sentences what the meaning of
the solution(s) are in relation to the problem situation. A rubric has been provided for
reference.
1. An object is propelled off of a platform that is 75 feet high at a speed of 45 feet per
second (ft./s). The height of the object off the ground is given by the formula
h(t) = - 16t+45t+75, where h(t) is the object's height at time (t) seconds after the
-16
object is propelled. The downward negative pull on the object is represented by
Solve for t.

Phenomenon: Runaway Truck Ramp A truck was driving on a highway at 30 m/s when its brakes gave out. The driver steered it onto a “runaway truck ramp”, consisting of an upward ramp (rising 12 meters vertically over 120 meters horizontally), and ending with a compressible barrier which you can model as a giant spring with spring constant “k”. The compressible barrier can be compressed by a maximum 0.5 meters before it stops working. Graphic attached Values: Mass of the truck: 20 metric tons (1 metric ton = 1000kg).
