close. At about 90 degrees after TDC the exhaust port opens ending the power stroke. A pressure wave of hot expanding gasses flows down the exhaust pipe. The blow-down phase has started and will end when the transfer ports open. The pressure in the cylinder must blow-down to below the pressure in the crankcase in order for the unburned mixture gasses to flow out the transfer ports during the scavenging phase. 2) Now the transfer ports are uncovered at about 120 degrees after TDC. The scavenging phase

The accounts of the defeat of Babylon from Herodotus and the Cyrus Cylinder are polar opposite, one defeat is through attack while the other is a peaceful take over. Herodotus’ version indicates that Cyrus was led by a need for power, Herodotus writes that after “having subdued the rest of the continent, [Cyrus] turned his attention to Assyria” (78). In Herodotus’ account, after Cyrus spent an entire summer “punishing” a river, he was met with Babylonians awaiting his arrival, and they “attacked

“How To Determine The Life Expectancy Of A Car Battery” Car battery is the prime part of an automobile. It is an essential part that starts the engine of a car. Moreover, it plays a big role in stabilizing, filtering, giving power for ignition, electrical lighting, and other car accessories. The life expectancy of a car battery is usually around four to six years. And sometimes, car battery does not last longer than your expectation. Anyhow, there are still ways that can help in increasing the life

INTRODUCTION A V-twin engine, also called a V2 engine, is a two-cylinder internal combustion engine where the cylinders are arranged in a V configuration.Gottlieb Daimler built a V-twin engine in 1889. It was used as a stationary power plant and to power boats. It was also used in Daimler's second automobile. In November 1902, a V-twin engine motorcycle, and in 1903 V-Twins were produced by other companies. Also, in 1903, Glenn Curtiss in the United States, and NSU in Germany began building V-twin

shown an interest lately in our coloured wooden shapes and also in our cylinders. They have been observed looking into the cylinders like binoculars as well as looking through the coloured area of the shapes like they are glasses. Therefore our activity today was a combination of both of these observations. Our nursery educator Kat taped coloured cellophane (primary colours – blue, red, and yellow) to one end of the cylinders to allow the children to continue their exploration. This is an opportunity

who have owned a John Deere two-cylinder tractor have most likely wondered why it makes a “putt putt” noise when it is running. The engines in the two-cylinder tractors were very similar in shape, but not in size. The biggest tractor, the model D, had a 501 cubic inch engine (TractorData). The smallest tractor, the model L, had a 66.4 cubic inch engine (TractorData). The tractors that were smaller and were meant for lighter duties have a vertical inline two-cylinder engine. This means that the pistons

on what they are. II Equipment The late nite lab was used to conduct this experiment. The product used were a balance, a graduated cylinder, water, Ethanol, and unknown liquid, Iron and an unknown metal. III Procedure There were four different small experiments to look at density. In experiment 1 a balance was taken and put to zero. Then a 50 mL graduated cylinder was put on the balance. The mass was

Qualitative Data: It was evident that after the potato cylinders were taken out from the sodium chloride solution after an hour, the ones that gained mass had increased in rigidity, becoming more turgid as well as appearing bigger than before. Their color also changed from distinct yellow to a lighter shade of yellow. On the other hand, potato cylinders that were put in a high concentration solution shrunk in size and they became shorter in length since they lost water. They felt softer, more flexible

Next, is the verification and determination of pure liquids. A clean and dry a 25mL graduated cylinder must be gathered from the lab cart, weigh the dry cylinder to the nearest mg and record the data. Add distilled water to the cylinder making sure the water level is at above the 20mL mark but below the 25mL mark. Determine and record the temperature of the water in the cylinder. Then, reweigh the cylinder to the nearest milligram. Calculate the density of the water then compare the measured density

sucrose on the rate of osmosis in cylinders of potatoes. This would happen by using similar sizes and lengths potato cylinders and applying them to different concentrations of sucrose(0%, 10%, 20%, 40%) in small beakers then measuring the change in mass of the potato cylinders afterwards. Maintaining all variables unchanged such as pH, same size, and a constant temperature. time taken for all potato cylinders will be 30 minutes. Hypothesis If the potato cylinders were put in sucrose concentration

to determine patterns between the masses. We came up with 30 different pennies and split them into trials. We ]hypothesized that the more pennies that were added will create a greater volume. Material and Methods Lay out supplies Fill graduated cylinders to 20 mL each Weigh penny trials on weigh boats and balance First trial put 5 pennies in the

gained as well as how to utilize the error equations to account for margins of error in each experiment. For Investigation 1, the mass, length and diameter of four separate cylinders was measured and utilized to calculate the volume and density of the cylinders. After recording these results in the table, the data of the cylinders was graphed. Then, in Investigation 2, a Geiger counter was utilized to measure background radiation in the lab at intervals of one minute for sixty minutes. The time period

of a fluid can impact an object that you drop into it, because there’s a resistance of some sort impacting the rate of which they fall. For example, when both spheres were dropped at the same time into a graduated cylinder of water, the steel sphere hit the bottom of the graduated cylinder before the glass sphere, because the viscosity of water is low. The viscosity of water is very dynamic based on the temperature, but both of the spheres were denser

balance to find each coin’s mass and a graduated cylinder to find their volumes. With all this information, I can now form a hypothesis. My first hypothesis is if I put a quarter in a graduated cylinder and get the volume and weigh it, then it will have the greatest density. If I put a dime in a graduated cylinder and get the volume and weigh it, then it’s density will be between the quarter and the penny. And finally, if I put a penny in a graduated cylinder and get the volume and weigh it, then it will

OBJECTIVE The purpose of this experiment was to measure the density of an unknown metal object and use the measured density to insinuate a probable identity for the metal. PROCEDURE In part one of this experiment, an unknown metal object, a graduated cylinder, water, and a mass balance was first collected. The object was dried with a paper towel to avoid any water droplets and the mass balance was checked to read 0.0 g when nothing was on it. The first measurement that was retrieved as the mass of the

different properties of the tap water and oil. Density was measured using the mass of a liquid in a known volume, the specific gravity was determined by using a hydrometer, and viscosity was measured by using the weight of a falling mass to spin a cylinder completely submerged in the test fluid. The values determined from these tests could then be compared to known values to viscosity and density. Theory A fluid is defined as “a substance that deforms continuously under the action of an applied

and then record in a table. Then fill the graduated cylinder halfway with water and record the volume of the water precisely. Tip the cylinder gradually being cations as not to spill and slide the aluminum block into the graduated cylinder. Put the cylinder straight up and confirm the block is absolutely submerged. Afterwards record the volume. Extract the aluminum block from the cylinder and dispose of the remaining water and clean the cylinder before storing it away. For the second half of the

represented by the Cyrus Cylinder Inscription. The Cyrus Cylinder Inscription is a small clay cylinder made during the reign of Cyrus in the 6th century BCE. It contains a cuneiform inscription describing Cyrus' policies and beliefs, including his treatment of conquered peoples and his commitment to religious freedom. The cylinder is widely considered to be one of the earliest human rights documents in history. A key message of the Cyrus Cylinder inscription

The experimental hypothesis for this experiment was prove as the results from the experiment provide evidence to suggest so. The osmosis process was shown when the potato cylinders were submerged in the salt solution and over time this only became more prominent. Looking at graph A, the potato cylinders submerged in the water solution gained mass and became harder when pressure was applied. This meaning no osmosis happened as expect as the mass gain implies there was just passive transport. The
