Phy-102 Energy and Circular Exercises Question 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. b. Explain this using the work-energy theorem A. According to the impulse momentum the impulse must be dependent on the applied force. This is Impulse=applied force*time). The longer barrel allows the gases to expand more, which will push the bullet for longer. Which will have increa...

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...

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: 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...

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...
