Concept explainers
Explain all answers clearly, using complete sentence and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Alien Technology. Some people believe that Earth is regularly visited by aliens who travel here from other star systems. For this to be true, how much more advanced than our own technology would the alien space travel technology have to be? Write one to two paragraphs to give a sense of the technological difference. (Hint: The ideas of scale in this chapter can help you contrast the distance the aliens would have to travel with the distances we currently are capable of travelling.)

- 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?arrow_forwardRead 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.arrow_forwardFor the following questions, THERE IS NO NEED FOR EXPLANATION. PLEASE PROVIDE JUST THE ANSWER THANK YOU.
