Volume Three

g 6 2.48 g 7 2.50 g Chart 1: Analysis: The mass of 1 drop of water is 0.4g. By taking the total mass and dividing it by the number of drops we can figure out the average mass of a drop of water. However the number of drops should be more than three as we have to take into consideration that the mass of the boat is combined with the mass of the drops. However, we are measuring the combined weight of both and therefore there is no need to measure the mass of the boat by itself. The major…

these values we were to find the area, volume, and density of the block of wood. We also calculated the maximum area, volume, and density using the uncertainty values that we were…

clips are difficult to hide. 2. Strand-by-Strand Method The stylist attaches small hair extensions one at a time to your natural hair. How many extensions the stylist installs depends on the desired results. A technique such as this requires two to three hours to apply all the extensions. 3. Tape-In Method Tape-in hair extensions come with adhesive tape on one side of them. The stylist simple applies these extensions to one layer of natural hair. Multiple applications will increase the…

out to 55.854g, then after subtracting the mass of the graduated cylinder the total mass of the sand came out to, 15.529g. The volume of the water came out to 6mL after adding 10mL of water and assessing the water displacement. Then using the density formula, (d=m/v, d=15.529/6), the density came out to 2.588g/mL.…

For our first model we choose to make four rectangular prisms, and one cube to make a pair of glasses for the two Ping-Pong ball model. We choose these shapes because, we both knew how to find the surface area and volume of them to the point where it wasn’t easy, but it was not super difficult. We felt safe using these shapes. When put together they also can be taped together perfectly to resemble a pair of glasses. We thought that this would be a great model to make…

of the cubes. In order to do so, the mass of each of the two cubes, and the slab were taken, and the dimensions of each were accurately measured. The dimensions were multiplied to find the volume, and the volume and mass were then used to find a comparable value, the density of each object. The mass and volume of an irregularly shaped stone were then found, and from this, the density of the stone was calculated. The density of the dot cube and slab were within the same margin, and therefore are…

we are measuring the ranges R of the ball as the function of the heights, H, that the ball is dropped from. I will use these data to determined the relationship between the height and the range. Procedure We divided this experiment into three parts. In the part one, the object was to observe the scatter in data. To do this, we set up the equipment: the bounce plate is 20 cm above the table ,the drop plate 20 cm above the bounce plate, a piece of carbon paper over a large piece of…

the experiment included water-displacement, measuring copper’s dimensions, and using volumetric pipettes to measure out specific soda volumes. Beginning Question(s): How does the use of two experimental methods, improve the chances of calculating the density of copper? How does the density of non-diet soda compare to that of diet soda measured at different volumes? Safety Statement: In both labs, students need to handle the volumetric pipettes, balance scales, and glass equipment carefully. Any…

survey. Due to the poor quality of some images, percentage cover estimates from two transects within Rec3 were generated using only two images, and were not calculated for two transects within M7 which were excluded from the statistical analysis. Three transects (all within site M4) contained 100% macroalgae cover; therefore sediment type classification was based on the dominant sediment found at the entire site. Model selection…

The average for the normal amount of flour cookies were 1.0 cms. For the least amount of flour batch was 2.67 cm. For the most amount of flour the average was 1.5. The first three cookies had 160 grams of flour in it. The heights of those three cookies stayed the same at 1.0 centimeters tall. The second batch of cookies had 96 grams of flour in it. Two of the cookies stayed the same at 2.0. The third one bumped down to 1.5. The final batch had 224 grams…
