    The current standard for the kilogram is the International Prototype Kilogram. The International Prototype Kilogram, also known as Le Grand K, is a platinum-iridium bar made in the 1880’s. This official Kilogram is kept in a vault in Paris under two glass domes. The reason it is under 2 glass domes it to prevent dust from obstructing from the weight of the Kilogram. However according to Sandia National Laboratories, a government organization under the Department of Energy, “Of the seven units of measurement in the International System, or SI, the kilogram is the only base still defined by a physical object. In addition, copies of the kilogram have changed over time by either gaining or losing weight as compared to the standard kilogram.”(DOE/Sandia…

    This experiment was implemented to find out if water will pass through the membrane to a solution of a advanced concentration. The procedure of osmosis is vital for all living entities. So, to understand Osmosis is to understand all living things. When a solution that has the same osmotic weight as another substance, mostly one in a cell is said to be Isotonic because the solutes inside and outside of the cell or the same (Microscopy and Microscopes Magazine 2013). They balance each other out.…

    Objective: The purpose of this lab was to examine Newton 's second law by observing the relationship between force and acceleration in a friction-free environment and to illustrate the concept of mass. The experiment was conducted in such a way to reduce friction. In order to simulate this environment an air-cushioned track was set-up for the glider to ride on a pocket of air without being in contact with the metal track. In addition, this glider will have masses attached to it as well as a…

    stances are called the ‘feet-apart’ pose and the ‘feet- together’ pose as shown in Figure 1-1. An angled-body posture, by displacing the center of mass both forward and downward, can help reduce the amount of torque that the pushing ankle needs to counteract. The statically displaced center…

    angle we used the formula α+β, and for the F_2 angle, we used 180-(β+γ). For the second part, in order to find the sum of the x and y components separately we use ∑▒fx= F_1x+F_2x+F_3x and ∑▒fy= F_1y+F_2y+F_3y, respectively. After finding the sum of the x and y components, we find the resultant by plugging the values into R= √((∑▒〖fx)〗^2+(∑▒fy^2)). Then to find the angle of the resultant we use tan⁡θ=(∑▒fy)/(∑▒fx)→θ=〖tan^(-1) (〗⁡〖(∑▒fy)/(∑▒〖fx)〗)).〗 Lastly, in order to know the…

The other tool in the office is the vacuum that makes the most annoying “shvooooo” noise when someone sucks up a sample of weight. “Think you are ready to do it on your own?” Bryan asks cautiously. “Yes, I am ready to do this. Thank you for showing me; I will not let you down” I said. “Do not worry about messing up. We have all…
