5. Compute a linear least-squares-fit of the calibration data and plot the resulting line on the same graph as the calibration data. Comment on the linearity of the pressure transducer and scannivalve. Part 3: Calibration of the Tunnel 1. Connect the micromanometer (calibrated in Part 2) across the wind-tunnel contraction in order to measure the static pressure drop.
Take that difference and divide by the actual value (given in this problem) of tin’s atomic radius. Take your answer and multiply by 100 to make it a percentage, and that is your percent error. Percent error is a common calculation in science. Your grade will not be determined by the amount of error, but just that you used the calculation correctly. (140-145)/ 140 x = 3.5 6.
Then Kaku states that force fields can do more than deflecting laser beams because it can levitate objects by the use of magnetic force fields. To support that, he explains that when we place two magnets opposite to each other, the two magnets will repel each other. However he wrote that making force fields and to levitate heavy objects is nearly impossible since we lack advanced technology. For my response, Kaku doesn’t completely explain everything. Suppose that you have a structure on a planet or a spaceship in the middle of nowhere, and suppose you don't want the force field on all the time either because there are times when protection isn't needed.
AQA GCSE Physics New Unit 2 Summary Notes Physics Unit 2 Revision (Higher tier) Forces Forced act in pairs. When 2 forces interact they are equal and opposite in direction e.g. a person exerts a force on the chair but the chair applies an equal force upwards on the person, a reaction force. Weight is also a force measured in newtons. Don’t confuse mass and weight as mass is actually the amount of ‘stuff’ that makes up an object measured in kilograms.
Homework Unit 57 Section 7 1. What friction rate should be used to size a duct for a static pressure drop of 0.1 in wc if the duct has a total equivalent length of 150 ft? (57.10) 2. What size metal duct should be used to deliver 170 CFM with a pressure drop of 0.15 in wc if the total equivalent length of 130 ft? (57.10) 7 in.
Module 3: Natural Forces Affecting the Driver Vocabulary: Please define six (6) of the following terms in your own words. Please do not just copy and paste the definition. 1. Gravity - The force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
iVelocity and Acceleration Calculation Worksheet DIRECTIONS: Solve the following situation problems using equations for velocity and acceleration. 1 What is the speed of a rocket that travels 9000 meters in 12.12 seconds? 2 What is the speed of a jet plane that travels 528 meters in 4 seconds? 3 After an impact involving a non-functioning satellite, a paint chip leaves the surface of the satellite at a speed of 96 m/s. After 17 seconds, how far has the chip landed?
In this experiment, frictional forces heat an aluminum calorimeter. The work of friction should be equal to the heat energy gained by the calorimeter. The heat energy gain can be easily found by measuring the change in temperature (ΔT) and by knowing the mass of the aluminum calorimeter (Mc). The heat energy gain Q is given by Equation (2). Q = Mc Cc ΔT (2) Where Cc = 0.215 cal/(g °C) A nylon cord is wound five times around the aluminum calorimeter.
Also this lab teaches about measurement uncertainty can be calculated using the percent error equation. These are the purposes of the lab. My hypothesis of this experiment is that the velocity of an object, the ball rolling down a ramp or falling down, changes at a constant rate, thus uniform acceleration occurs. Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity over time. An object accelerates if its velocity is constantly changing, also known as speeding up or slowing down.
Procedure 3: The Compound Pendulum The aim of this experiment is to determine the value of the acceleration due to gravity by measuring the period of oscillation of the pendulum when suspended from different distances from its centre of mass. A pendulum consisting of any swinging rigid body which is free to rotate about a fixed horizontal axis is called a compound pendulum. This experiment had to be carried out at Glasgow University as the required equipment was not available at school. Procedure 1) The pendulum was balanced on a large brass knife edge to determine the position of the centre of mass of the pendulum. 2) The larger moveable knife edge was then clamped to the pendulum, at a small distance (1cm) above the centre of mass.
