PHY-102: Motion Exercises Complete the following exercises. Jane is collecting data for a ball rolling down a hill. She measures out a set of different distances and then proceeds to use a stopwatch to find the time it takes the ball to roll each distance. What is the independent variable in her experiment? The independent variable is represented by the ball. What is the dependent variable in her experiment? The Dependent variable is represented by the stopwatch. Give one control va...

PHY-102: Motion Exercises Complete the following exercises. 1. Jane is collecting data for a ball rolling down a hill. She measures out a set of different distances and then proceeds to use a stopwatch to find the time it takes the ball to roll each distance. a. What is the independent variable in her experiment? The ball would be the independent variable because it is not dependent on any other variable. b. What is the dependent variable in her experiment? The stopwatch would be t...

PHY 102 MOD 4 Exam Name Aalicia Tucker 30 Questions Submit to an Individual Forum or email () Please delete this file after receiving a grade HIGLIGHT THE SINGLE CORRECT RESPONE 1. Which of the following activities best illustrates the practices of the scientific method? a. Deciding on the materials necessary to build a terrarium. b. Following the instructions to construct an electric generator. c. Measuring the time for an object to fall from different heights. d. Designing an electr...

PHY-102: Fluid and Thermal Physics Exercises Complete the following exercises. 1. Rank the following in terms of increasing density: A. A100 g object with a volume of 25 cubic centimeters B. A 200 g object with a volume of 100 cubic centimeters C. A 100 g object with a volume of 100 cubic centimeters D. A 400 g object with a volume of 50 cubic centimeters 1.C, B, A, D 2. Rank the following in terms of increasing pressure: A. A 10 kg object distributed on a square surface with dimensio...

PHY-102: Fluid and Thermal Physics Exercises Corrections to the following: 1. CBAD; FEEDBACK: Calculate the density using Density = (mass) / (volume). 4. DBAC; FEEDBACK: The blocks with higher density will have a larger mass, and thus a larger force of gravity. For C the force of gravity is greater than the buoyant force, while for the other three it is equal to the buoyant force. Since the buoyant force is smallest for D (least volume of liquid displaced), a little greater for B and e...

PHY-102: Energy and Circular Motion Exercises Complete the following exercises. 1. A rifle with a longer barrel can fire bullets with a larger velocity than a rifle with a shorter barrel. a. Explain this using the impulse-momentum theorem. By the theory of momentum, change in momentum of an object equals the impulse applied to it meaning that the long barrel of the rifle covers a huge amount of motion of the bullet since the bullet receives more impulse from the expanding gases with...

She measures out a set of different distances and then proceeds to use a stopwatch to find the time it takes the ball to roll each distance. a. What is the independent variable in her experiment? The ball b. What is the dependent variable in her experiment? The stopwatch c. Give one control variable for her experiment. The different distances 2. Consider an experimen...

PHY-102: Electricity and Magnetism Exercises . 1. Why are good conductors of heat also good conductors of electricity? Good conductors of heat are also good conductors of electricity because electricity causes heat through electrons. Free electrons, electrons that roam freely though a substance, carry heat and electricity because of the free electron theory. 2. What is the difference between a good conductor and a good insulator? The difference between a good conductor and a good in...

Complete the following exercises. 1. Both, the thermal conductor and electric conductor relies upon the nearness of free electrons in the substance. Number of free electrons in any substance is in direct linking with the pace of warmness and electric transmission. As both thermal and electric transmission relies upon proximity of free electrons, thus, the resources, which are great conductors of warmth, are in addition the great conductions of electricity. 2. What is the difference ...

PHY-102: Energy and Circular Motion Exercises Complete the following exercises. A rifle with a longer barrel can fire bullets with a larger velocity than a rifle with a shorter barrel. a. Explain this using the impulse-momentum theorem. A rifle with longer barrel shoot shots with bigger speed when distinguished with rifle with shorter barrel, on the grounds that, as indicated by drive energy hypothesis, motivation is reliant on the connected power and time for which the power is conne...
