WGU C165 INTEGRATED PHYSICAL SCIENCES EXAM QUESTIONS AND ANSWERS 2023/2024

WGU C165 INTEGRATED PHYSICAL SCIENCES EXAM QUESTIONS AND ANSWERS 2023/2024. WGU C165 Integrated Physical Sciences 2023 1. A mathematical model is used to predict the trajectory of a bullet fired from a gun. Which discipline of physical science is used to develop this model?: Physics 2. An environmental scientist monitors pollutants in a lake. Which two disciplines of physical science does this scientist use? Choose 2 answers: Chemistry Earth Science 3. Which study involves both Earth science and physics?: Calculating how much energy is associated with a hurricane 4. Which question could be answered with a controlled experiment?: Does ice melt faster in an empty glass or in a glass full of water? 5. Which topic would be appropriate for a controlled experiment?: Determining how fast different chemical pollutants dissolve in water 6. Sir Isaac Newton discovered that the force of gravity between two masses increases if the masses increase, and decreases if the distance between the masses increases. No experiments have ever contradicted this relationship. Which type of scientific statement is this?: Law 7. The well-accepted scientific explanation for many characteristics of Earth's crust states that the crust is broken into several large plates. These plates move slowly over the mantle below because of convection and other processes. Earthquakes and volcanoes are most common at places where the plates interact. Evidence from physics, chemistry, and geology supports this explanation. Which type of scientific idea is this explanation an example of?: Theory 8. Which question requires a controlled experiment to answer?: Which type of rock contains the most calcium? 9. A student proposes that sugar will dissolve faster in rubbing alcohol than in water. The student reasons that sugar and rubbing alcohol both contain carbon so they will mix more easily. Which type of scientific idea is the student's proposal an example of?: Hypothesis 10. Why was the shrinking Earth idea replaced by the theory of plate tectonics?: Plate tectonics explained observations about Earth that the shrinking Earth idea could not explain. 11. Astronomers have long accepted that plate tectonics exists nowhere in our solar system except on Earth. In 2011, a scientist analyzed 100 NASA-space-mission photographs of Valles Marineris on Mars, the longest known series of canyons in the solar system. The scientist found that Valles Marineris showed features found only in locations on Earth where major tectonic plates divide. What would be the appropriate response of scientist
