5. Determine the mass of the penny on the balance, and record the mass in the table on the bottom of the page. Removed the penny from the balance using tweezers and place it in its beaker.…
For the purposes of this experiment, the mass will be measured using a digital balance and the volume will be measured directly using a ruler and calculated using the volume formula {fig.1} for a cylinder.…
The mass of ten pennies minted before 1982 was calculated five times using the scale and then averaged. These steps were repeated with the pennies minted after 1982. 30 milliliters of water was placed into the graduated cylinder. The pennies minted before 1982 were placed in the water and the new volume was recorded and used to calculate the volume of the pennies. The five calculations were averaged. These steps were then repeated with the pennies minted after 1982. The precision of the mass and volume data was calculated. The mass calculations were divided by the volume calculations to find the densities for both sets of pennies.…
Part 2: I used a graduated cylinder on the tarred scale empty and then with both water and isopropyl alcohol to determine the mass of both and calculated their densities. Next, I measured the length, width, and height of a magnet to determine volume. I then used the water displacement method by filling a cylinder with water and then placing the magnet in and recording the difference in the water level to determine volume and density. Lastly, I used Archimedes’ method to by recording the mass of a metal bolt then placing it in water and observing the displacement. I then converted this to density of water and repeated with a magnet.…
* The calculated volume is more accurate than the Archimedes’ Principle because it may have a higher percentage of error.…
Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.…
5. The reason Ben’s boat didn’t float is because the boat sinks because its weight is greater than the displaced water’s weight. To fix it Ben would have to spread the volume of his boat out or put his boat in more dense water.…
Step 2: The materials remaining are milk jugs, aluminum soda cans, and soda bottles. The next step involves the large water tank and nets for skimming the materials out of the bottom of the tank. Next, I simply put the rest of the materials in the tank. The only material that should float should be the milk jugs because they are less dense than the water. The milk jugs are 0.9 grams per cubic centimeter, the water is 1 gram per cubic centimeter. The aluminum soda cans and soda bottles sink because they are more dense than water. The aluminum soda cans are 2.7 grams per cubic centimeter and the soda bottles are 1.4 grams per cubic centimeter. If an object is more than 1.00 grams per cubic centimeter it will sink. If an object is under 1.00 grams per cubic centimeter it will float. The workers then take out the milk jugs floating above the water with their skimmers.…

Awakening from General Zaroff’s comfortable bed, Rainsford felt he just had the most bizarre dream in his life. What happened slowly came back to his mind. He won in Zaroff’s hunt and then he fell asleep in Zaroff’s bed. Zaroff was the hunter who lived in the enormous building on Ship-Trap Island.…
One day, while Archimedes was getting into the bath tub, he noticed that the more he walked into the tub, the more water that ran out of the tub. He found out that when an object is immersed under water, there is a volume…
Results. For our experiment, we started with a piece of tin foil that measured 13.5 cm long by 11.5 cm wide. We fashioned that piece of tin foil into a flat-bottomed ship which measured 11 cm long by 8.5 cm wide by 1 cm high. We calculated the volume of our ship to be by multiplying the length by the width by the height which gave us a volume of 85 cm3 We then calculated the predicted number of pennies it would take to sink our ship by taking the volume of our ship and multiplying it by the density of water using the following formulas and then dividing that result by the weight of a penny (2.5g) which we rounded to 37 pennies. After we had our prediction of how many pennies it would take to sink our ship, we placed the ship into a container…
The objective of this experiment is to use the Archimedes principle to evaluate the specific weight of all of the separate materials. This objective of this experiment is significant in that it gives valuable information on how to determine the material composition of an object when given very vague information. From information learned in the accompanying Fluid Mechanics lecture course, basic formulas can be applied to solve for the specific weight of the object in question. The experiment performed will involve the buoyancy principle and include calculating the volume displaced of a submerged object.…
