WGU C165 Final Exam Questions With Verified Answers | Latest 2023/2024 Graded A+. It is often said that you can never prove a scientific theory right. Why? It is impossible to directly test every single instance in which it applies. A theory is just a guess. Science can never prove anything either right or wrong. A theory becomes a law once it is tested that thoroughly. Laws are statements of simply what is observed in all available experiments, while theories are explanations and typically apply to whole groups of phenomena. Laws do not become theories. Question 13 of 14 Which of these is generally regarded by scientists to be the basis for deciding issues in science? personal faith in the particular idea proposed whether the idea is the simplest one the researcher can think of the reputation of the researchers for careful work empirical evidence including experiments and observations Laws and theories are based on and supported by a wealth of evidence and facts. Question 14 of 14 Which of the following describes how scientific investigations are carried out? Scientists settle scientific issues by staging a debate to decide which side gave the best presentation. Scientists settle scientific issues by forming a consensus in the scientific community about which explanation is the most appealing. Scientists all follow the same list of four steps to make a discovery: observe something, hypothesize about it, test the hypothesis, and form a theory. Scientists use different procedures but rely on evidence and testing to confirm their ideas. Scientists follow many different procedures, depending on the nature of the research problem and their own creativity in finding ways to gather information. UNITS AND MEASUREMENTS Question 1 of 5 Why is it important to have standard measures for physical quantities? To make measurements, such as length, easier to perform. To make it more difficult for scientists to exchange and compare results of their measurements. To allow scientists from other countries to use standard measures and not make up their own units To allow for the comparison of measurements with anyone familiar with the measurement system. This is irrelevant to standard measures. Question 2 of 5 What is the official SI base unit for time? second hour meters/second kilograms Seconds measure time. Question 3 of 5 Which of these has values that are expressed in terms of a derived unit in the SI system? area mass length time Time is one specific measurement. Question 4 of 5 What device is commonly used to measure temperature? ruler thermometer clock scale Thermometers use the expansion property of a fluid with increasing temperature to measure temperature. Question 5 of 5 Which of the following pairs of variables has an inverse relationship? the speed of a hurricane's winds and the amount of damage they cause" how hard an object is pushed and how fast it moves Your driving speed and the time required to drive a certain distance the volume of a sample of liquid and the mass of the sample This is an inverse relationship because, as your speed increases, the amount of time to reach a specific point decreases. Earth science physics chemistry Chemistry deals with how atoms join to each other in different ways to form molecules of various substances. SCIENTIFIC INQUIRY Question 1 of 20 Which field of physical science deals MOST directly with which atoms join together to form molecules, such as the water molecule or the nitrogen molecule, represented below? Question 2 of 20 Which field of physical science MOST directly explains how the motion of the continents over 100 million years led to mountains and volcanoes in some places above land, and deep ocean trenches in other places beneath the ocean surface? chemistry Earth science physics Earth’s features and the processes that change them are the subject matter of Earth science. controlled experiment field study laboratory study The researchers would have to travel to actual rivers to gather their data. Question 3 of 20 Satellites orbiting Earth scan the light reflected from below, and the data can then be analyzed to get information about the objects that reflected the light. This technology is called “remote sensing.” For example, they can even distinguish between astroturf in a football field and real grass on the ground below, even though these look the same to the human eye. Which field of science would MOST directly devise ways to detect and analyze reflected light obtained by remote sensing? life science chemistry physics Earth science Detecting and analyzing reflected light is dealt with by physics. Question 4 of 20 Which type of scientific study is BEST suited for collecting data that will be used to analyze statistical information about the kinds of meanders, or turns, in the path of rivers such as the one shown in the photograph below?
