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.
17.”Observing” the early Universe. The only way we have of studying the era of nucleosynthesis is through the abundances of the nuclei that is you left behind. Explain why we will never be able to observe of that era through direct detection of photons emitted at that time.

- 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.arrow_forwardSolve the following problem and show your complete solutions. Explain your work for better understanding.
