WGU C165 Integrated Physical Sciences Questions and Answers-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 An environmental scientist monitors pollutants in a lake. Which two disciplines of physical science does this scientist use? Choose 2 answers - 1. Chemistry 2. Earth science Which study involves both Earth science and physics? - Calculating how much energy is associated with a hurricane Which question could be answered with a controlled experiment? - Does ice melt faster in an empty glass or in a glass full of water? Which topic would be appropriate for a controlled experiment? - Determining how fast different chemical pollutants dissolve in water Which question requires a controlled experiment to answer? - Which elements are found in Earth's atmosphere? 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 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 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 Why was the shrinking Earth idea replaced by the theory of plate tectonics? - Plate tectonics explained observ
