8/11/14 The purpose of this lab is to calculate the density of aluminum with different masses and volumes of aluminum bits and water. Aluminum Bits balance graduated cylinder water cupcake liners paper towels 1. First‚ get materials ready for the experiment by cleaning and/or drying materials 2. Mass the cupcake liner 3. Add water to the graduated cylinder and record the volume of water added. 4. Place some aluminum pebbles into the cupcake liner and place it on the balance. Record

propagation laws. Find the electric field strength at the mobile location. Also find the power flux density Φ in w/m2 for users along the horizon. b. Repeat for the two-ray model‚ assuming a tower height of 40 meters‚ a mobile height of 2 meters‚ and a plane earth approximation. Assume the transmitted signal is verticallypolarized‚ and that the earth reflection coefficient magnitude is 1. c. Plot both power flux densities versus d on log-log scales‚ over a range from 100 meters to 10 kilometers. You should see

In this lab‚ there was a comparison between accuracy and precision of densities measured by volume. Mass measurements are often used units in the metric system. Volume can be examined a borrowed unit. The volume measurements were made in mL. Every measurement had a level of hesitancy affiliated with it. The experiment could feel uncertain from the object used for measurement and from the accuracy of the person doing the measuring of the volume. Because of this uncertainty‚ the experiment must be

There were several drops of the water cling to the beaker. This may increase the actual mass of water in each trial. In the density part‚ the mass and density of zinc electrode was measured and calculated to determine the accuracy of the measurement. The result shows that the densities of zinc electrode in two trials are 6.2±1.6 g/cm3 and 9.4±3.8 g/cm3 (The average density is 7.8±3.8 g/cm3)‚ which is not quite accurate‚ compared to the standard of solid zinc density1 (7.14 g/cm3)1.

calculating the mass and dividing it by the volume to get the density‚ then compare densities. 44. A student has several different-size samples of substances I and II. She measures the masses and volumes of these samples and plots the graphs shown in Figure D page 67. Which substance has greater density? How do you know? 2 2 more dense because it doesn’t rise as fast as number one. 45. How can you determine the density of ice? Can you determine the volume of the ice by melting it

The data 5 able to get knowledge of density by using digital scale and common products salt and isopropyl alcohol; we gain from this experiment‚ that more saturated solution the higher it mass. After we used irregular objects metal bolt and magnet to find a density and used displacement method‚ it recorded under data 6; by using the formula density equal to the mass of its volume. The 7th data using Archimedes’ Method‚ noted that using irregular

Archimedes’ & Pascal’s Principle Purpose In this lab‚ we will prove Archimedes’ Principle by finding the density of a Metal Cylinder‚ a cork‚ and an unknown fluid by using Archimedes’ Principle. We will also use the PASCO Pascal’s Principle Lab Setup to investigate the use of fluid pressure as a hydraulic system to do work and we will find its mechanical advantage. Procedure For the first part of the lab we will be verifying case 3 as explained by professor. We
