WGU C165 Integrated Physical Sciences Test Prep Questions and Answers (Verified Answers)
INTRODUCTION TO PHYSICAL SCIENCE
Question 1 of 14 Auroras are bursts of light that happen when charged particles from the sun interact with Earth's magnetic field and atoms and molecules in our atmosphere.Which physical science is BEST SUITED explain the interactions of the charged particles with Earth's magnetic field?life science physics chemistry Physics can explain the interactions of charged particles with the Earth’s magnetic field because magnetic fields are forces.Question 2 of 14 The physical science that is BEST for finding the best locations to drill for the petroleum used to make the candles is Earth Science.Earth science is best suited to study Earth’s structure, including the mechanisms and likely locations for petroleum reservoirs to collect.Question 3 of 14 The science BEST for studying how hydrogen sulfide and carbon dioxide react is Chemistry.Chemistry focuses on the study of atoms and molecules, their structures, and their interactions to form various substances. 1 / 4
Question 4 of 14 The science BEST for studying photosynthetic bacteria is Life science.Life science focuses on environments, biological entities, and many other related fields. 2 / 4
Question 5 of 14 Which of the following terms best describes a research project that involves sending a space probe to a distant asteroid to land on it and collect data?a controlled experiment a field study a laboratory experiment Even though the scientists are not on the asteroid, they are conducting data collection in the field.Question 6 of 14 A main reason to do a field study rather than a laboratory experiment is if Question 7 of 14 Which of these fields depends the MOST on observational studies? physics Earth science chemistry While scientists today have many techniques and procedures to replicate unique experiments that answer can answer questions about the Earth, most of the data collected is still observed.Question 8 of 14 The kinetic theory of gases is based on the assumption that the molecules that form the gas are in random motion and bounce off the walls of their container and off each other as if they were billiard balls. The forces between real molecules are more complicated.This is an example of An observational study focuses on collecting data and observing phenomena in the field or laboratory. 3 / 4
Question 9 of 14 Why can’t astronomers carry out a scientific research study to determine which visible star, other than our sun, is the nicest?The Hubble telescope has better uses.Existing telescopes aren’t powerful enough.There is no way to prove any answer wrong.A project of that sort cannot get funding.“Nicest” is subjective. Consider the people who like summer versus winter, or vice versa.Question 10 of 14 Galileo found that when air resistance can be ignored, heavier and lighter objects fall in the same way. He tested this rule and confirmed it was consistent with all available data.The rule Galileo found can BEST be described as a The rule Galileo found was a tested conclusion describing something very specific that happens, and was supported by all available data.Question 11 of 14 Which of these describes a statement that has usually NOT yet been tested? a hypothesis a model a theory a law A hypothesis is a testable statement about how something in nature works. It is typically the best tentative assumption that researchers can make based on the evidence they already have at that point.
