PHYSICS 1 FAP0015 Questions & Answers to Physics I Assignments Chapter 1 11. What‚ roughly‚ is the percent uncertainty in the volume of a spherical beach ball whose radius is r = 2.86 ± 0.09 m? Answer: To find the approximate uncertainty in the volume‚ calculate the volume for the specified radius‚ the minimum radius‚ and the maximum radius. Subtract the extreme volumes. The uncertainty in the volume is then half this variation in volume. 3 Vspecified = 4 π rspecified = 4 π ( 2.86 m ) = 9

A hockey stick exerts an average force of 39N on a 0.2kg hockey puck over a displacement of 0.22m. if the hockey puck started from rest‚ what is the final velocity of the puck? Assume no friction. Your physics teacher walking with the aid of a cane approaches a skateboard of 3.5 kg lying on the side walk. Pushing with an angle of 60 degree down from the horizontal with his cane‚ he applies a force of 115N‚ which is enough to toll the skateboard out of his way. Calculate the initial acceleration

An air Compressor is one of the major energy consuming utilities in any industrial operation and are mainly classified in two types. The classification is based on their construction and operation features. The two main classification of Air Compressor are: 01) Positive Displacement Type 02) Dynamic Type. You will find details of each type from below description. 01) Positive Displacement Type Air Compressor. Positive displacement types compressor are those‚ who mechanically displace

Physics C-110 Module 1 Chapter 1 1. What is science? Science is a body of knowledge that is ever changing. It is made up of not only facts but also theories that are made up of well-tested hypotheses. 2. Distinguish among the scientific fact‚ hypothesis‚ law and theory As stated above‚ a theory is made up of well-tested hypotheses‚ which in themselves are well educated guesses yet to be proven. A fact is something that can change over time even though it was agreed upon by knowledgeable

Find the average final velocity. Start with a ramp height of two workbooks. Release the steel ball from your chosen release point. When the ball leaves the end of the meter sticks‚ start the timer. When the ball reaches the 30 centimeter mark‚ stop the timer. Repeat for 5 trials for each height. If there is an error in the trial‚ do not use that trial‚ and redo that attempt. Enter all data in data table 1‚ then calculate the average final velocities. Find the average acceleration. Start

from the results of the marble’s average speed‚ it was slower when it was at the top of the ramp rather than towards the middle or the end. This is why the marble picks up speed as journeys down the ramp. As for acceleration‚ it is the rate at which velocity changes over time. An object accelerates when there is a change in speed‚ direction‚ or both. Because the marble gains speed as it travels down the ramp‚ it has acceleration. Although the marble only has a change in speed and not direction‚ we can

be examining how the kinetic friction coefficient is altered by changing the mass‚ surface area‚ speed‚ and material contacting each other. In order to find this value‚ we will be using a pulley apparatus that will allow us to measure the average velocity and manipulate Newton’s Second Law of Motion to find the kinetic friction coefficient. Based on contacting each other. Procedures First we began by leveling the track using the bulls-eye leveler. Then we connected the pulley to the interface device
