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.
Looking for Evidence. In this first chapter, we have discussed the scientific story of the universe but have not yet discussed most of the evidence that backs it up. Choose one idea from this chapter—such as the idea that are billions of galaxies, that the universe was born in the Big Bang, or that we are “star stuff” — and briefly discuss the type of evidence you would like to see before accepting the idea. (Hint: It’s okay to look ahead in the book to see the evidence presented in later chapters.)

- 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_forwardUse a sketch, an equation in addition to your precise and concise description. Please give a very detailed answer. 1) Discuss the process of spontaneous parametric down-conversion.arrow_forwardPlease anwer the quesiton correctly and take your time Convert light-minutes to km by following the steps described below.1. A) What is the speed of light (300,000,000 m/s) in km/s? Note that 1 km = 1000 m.1. B)Use your answer to the previous question to find the distance traveled by light in one minute. Give your answer in millions of km. (Note that 1 million = 106).arrow_forward
- 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_forwardPlease include a complete answer. Do not skip any steps. Please double check your work and include notes where appropriate.arrow_forwardInstructions: Your task is to create a model in response to the prompts in the question below. Be sure to apply a model from this class and include the relevant diagram(s) for that model. And don’t forget to use the Claim, Evidence, Reasoning framework to present your solution. 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). Mass of the driver: Choose a reasonable value. Truck Ramp Dimensions: 12 meters vertical, 120 meters horizontal Spring constant k= 6.0 x 107 J/m2. Part 1: Big…arrow_forward

- Solve the following problem and show your complete solutions. Explain your work for better understanding. And illustrate the FBDarrow_forwarduse guess method if you cant use guess method like the example below dont do the question at all please and thank u please do it in guss method no other way Solving problems in Physics, we must always use GUESS method.Guess stands for: Guess: G Here you write down what is given in the questionUnknown: U Here you list what you have to calculate, to solve for.Equations: E here you list all the formulas you need to use to solve the problemSubstitution: S This first letter S in the word, you will just substitute what is given in theformula. You do not calculate anything. The calculations will occur at the second S: Solve. Whatis very important here is to carry with you the units of measure in the formula. Not only thenumbers. This is very important, once again.Solve: S The last step, second S, you will solve what you plugged in the first S for Substitution.Very important here is to manipulate the units of measure such that the final units of measureto be proved by your work. This part…arrow_forwardPlz show full explanation and working with steps. Clear writing also to help with revision. This is 1 question I should add just with related parts. Thanksarrow_forward
