Turn in PHYSICS your completed worksheet to your teacher. ' PROBLEMS Short Response 1) What is a scientific discovery (whether discussed in this course or not) that would not have been possible without one of the important scientific discoveries discussed in this course? 2) What is one way that the study of physics can help explain phenomena in a seemingly unrelated field, like biology? 2 3) Aside from becoming a physicist, what is one career path that could be helped by a strong understanding of physics? 3 4) What is an example of a scientific topic that requires knowledge of at least two different branches of physics? 5) How has an advancement in physics impacted your day-to-day life?Dashboard | Colorado x Algebra 2 A (FA22) 2 x *Search Results | Cour x Physics A (FA22) 1 - / X Microsoft Word - Phy: x Error and Significant F X Principles of Business X + C A s3.amazonaws.com/content.accelerate-ed.com/Secondary/docs/PhysicsA/PhysicsA_Mod1_Homework_CP.pdf * IM Microsoft Word - PhysicsA_Mod1_Homework_CP 2 /4 100% + HO 6) How would you differentiate between a theory and a hypothesis, when reading a scientific text? 7) When you are reading the results of scientific experiments, what are some features that you would expect to see in the design of a high-quality experiment? 8) What is one way that complete and accurate laboratory reports help prevent bias and fraud from influencing scientific findings? 2 9) How does improving measurement accuracy help provide more valid scientific results? How does improving measurement precision help provide more valid scientific results? 3 10) Gerard is measuring the speed of a remote-controlled airplane. He measures that the airplane travels 110 m in 5.4 seconds, giving a speed of 20 m/s. What will Gerard need to change, if he wants to get a more precise value for speed?Dashboard | Colorado x Algebra 2 A (FA22) 2 x * Search Results | Cour x Physics A (FA22) 1 - / x Microsoft Word - Phy: x * Error and Significant F X Principles of Business x + C A s3.amazonaws.com/content.accelerate-ed.com/Secondary/docs/PhysicsA/PhysicsA_Mod1_Homework_CP.pdf * IM Microsoft Word - PhysicsA_Mod1_Homework_CP 3 / 4 100% + 11) Which of the following values has the greatest number of significant figures? Justify your answer? 0.0004200 grams 714 meters 3.1*10^8 seconds 0.0994 volts 12) Consider the following data set. What would this data set look like if the measurements were more precise?

If the actual value is 2.04 volts, what is Gina's percent error? 3 14) A team of engineers is measuring the strength of a new material. They have measured the strength to be 112,000 Pa. If the engineers expect a measurement error of 2.5%, what is the range of likely values for the actual strength of the material?Dashboard | Colorado x Algebra 2 A (FA22) 2 x *Search Results | Cour x Physics A (FA22) 1 - / X Microsoft Word - Phy: x Error and Significant F X Principles of Business X + C A s3.amazonaws.com/content.accelerate-ed.com/Secondary/docs/PhysicsA/PhysicsA_Mod1_Homework_CP.pdf * IM Microsoft Word - PhysicsA_Mod1_Homework_CP 4/ 4 100% + 15) Find the area enclosed by a rectangle that is 1300 m wide and 1630 m long.
