...isopropyl alcohol, coconut oil and an unknown liquid. In order to determine the mass, volume and density the group measured the different samples as accurate as possible. The experimental density values were measured at 1.01 g/ml, 0.800 g/ml, 0.940 g/ml, and 0.800 g/ml respectively at room temperature. As the group calculated for the percent error, using the given formula, the result was below 3.00% for all the samples. The unknown liquid, kerosene, was identified by comparing the measured density with its theoretical value. As for the solid samples a wooden cube, rectangular plywood, a marble, and a pebble was used in the said activity. The experimental density values of the solid samples were measured at 0.500 g/cm3, 1.99 g/cm3, and 2.61 g/cm3 respectively. Finally, after accomplishing the study, the accuracy of measuring, the needed quantities and the mentioned results proved that such a great success was achieved. INTRODUCTION Density is the measurement of compactness of a substance which is mathematically expressed as the ratio of mass and volume. Density is an intensive property of a pure substance which means that...

...able to identify the unknown liquid sample to be kerosene as we compared it with its actual density value. For solid samples, a wood block, pebbles and a marble was examined. The density results were found to be 0.69 g/cm3, 0.53 g/cm3, and 14.21 g/cm3 respectively. Everything that let the overall results to be accurate and precision were the accuracy of the measurements of the samples. INTRODUCTION Density is an intrinsic property which means it doesn’t depends on the amount of a substance. It is defined as the amount of matter (usually as mass) occupying a unit volume. Density is commonly expressed in g/ml for liquids, g/cm3 for solids, and g/L for gases. It can describe the characteristic property of a certain substance. The formula for density is defined as D = M/V wherein M is mass of the material and V is the volume the material occupies. The mass of a liquid or a solid may be taken directly from a balance. Likely the same, the volume of a liquid sample may be read from a graduated cylinder. Certain formulas can be used to calculate the volume of regular solids such as cube, rectangle and sphere. Using these two key measurements, we could calculate the density of a certain material. MATERIALS AND METHODS The density of water, isopropyl alcohol, coconut oil and an unknown liquid were...

...Introduction Have you ever heard of mind games before? We are not talking about brain teasers or the John Lennon song, we’re talking about psychological games that almost everyone plays among each other all the time. You may ask your self, why do we play games? We humans are curios about surrounding and environment, playing games that engage and challenge our curiosity makes us feel more aware brain power, and that in itself gives us a sensation unmatched and our activities. Games usually seek out stimuli just slightly more complex than their preferred level of stimulation and eventually games provide that sort of stimulation. They also help the mind develop by teaching cooperation and competition, exploration, and invention. Mind Games: Definition Mind games or brain games are activities that are fun but challenge your brain. Games that make you think, strategize, and remember information, are all games that will help train your mind. In fact, many of these basic characteristics are what you find in many of the games you already play. Moreover, mind games are psychologically manipulative and deceptive practice intended to deceive or confused somebody. The purpose of these games is to improve your memory, thinking, reaction time, and cognitive ability. These games are especially...

...stays in solution and you don’t really notice it, but the carbon dioxide bubbles out as a gas that helps the bath bomb break up. How it works it’s When a bath bomb comes in contact with water, the baking soda and citric acid react to make carbon dioxide bubbles. This is an acid–base reaction, where baking soda is a weak base and citric acid is a weak acid i think by adding more citric acid and baking soda that it will fizz more than normal because it will have a bigger chemical reaction Hypothesis i think by adding more citric acid and baking soda that it will fizz more than normal because it will have a bigger chemical reaction. The more citric acid there will be the bigger reaction it will have when it is put in the water. Introduction Have you ever had a refreshing bath with bubbles or bath salts? What if you could use chemistry to create a bath-time treat that incorporated both fizzing bubbles and soothing salts? Such a combination does exist, and it's called a bath bomb. If you have never experienced one, these "bombs" become fizzy when they touch the water. Why? It is due to a chemical reaction taking place between different ingredients within the bath bomb. In this activity you'll get to make your own homemade bath bombs and explore how changing the ratio of the ingredients affects how much the bath bomb fizzes when it comes into contact with water. Then you can use your perfected method to make some bath bombs as a gift for Mother's Day! Background Bath bombs...

...Particles from the Universe 2.1 A Brief Introduction of Cosmic Ray The name of the cosmic ray came from the period when it was assumed as the electromagnetic radiation. Its components are mostly stable particles like protons, atomic nuclear or electrons. A fairly small proportion is stable antimatter. The diversity of the cosmic ray means the wide source of the cosmic ray. The source mat be the Sun or the distant universe through certain unknown mechanics. The cosmic ray can be divided into two types, the primary cosmic ray and the secondary ray. The primary cosmic ray is referred to as the cosmic ray generated from out of the solar system. These ray interact with the inter-planet matter and generate the secondary cosmic ray. Usually, among the cosmic rays that come into the atmosphere...

INTRODUCTION “Colombian consumers have become much more aware of the benefits of healthy eating habits. However, the extent to which they can act on that growing awareness is based, in large part, on income levels. Healthy options are simply more expensive than many less healthy options. In fact, demand for organic food is low among consumers in all income segments and it is not common to see organic products or healthy options on the shelves of most supermarkets and grocery stores. On the other hand, there has been increased demand among Colombian consumers for so called ethical...

...company. This report is based on a one of the world’s leading Information and Communication technologies company-Fujitsu LTD. The report includes a brief introduction of Fujitsu, to get more familiar with the company, its approach and activities. The report also includes an environmental analysis (SWOT), to see what are the strengths and weaknesses of Fujitsu LTD., and what opportunities and threats is the company facing. The research investigates 3 organisational goals that are planned to be reached in future and cascades the through the various business departments and levels-finance, marketing, human resources and operations. In this report we examine three different plans that Fujitsu has implemented over the past five years. From the research we observed that Fujitsu uses its own management philosophy, called Fujitsu way and we examined this approach through various points. In the report we reviewed how conceptual, human and technical skills are used in Fujitsu. We also considered how staff should be motivated in Fujitsu in order to reach the overall organizational goals. We conducted our research using various resources, such as ITB Library, Business Sources Premium and Emerald databases, Company’s website and Internet.

Answer the following 4 questions. What is the smallest probability the intersection of A and B can have? What is the largest probability the intersection of A and B can have? What is the smallest probability the union of A and B can have? What is the largest probability the union of A and B can have? .15, .4, .75, and 1 respectively. Extra 1.2 Suppose we are rolling 2 independent, fair 10-sided die. Let A be the event that the sum of the rolls is a prime number. Let B be the event that the sum of the rolls is odd. Let C be the event that the sum of the rolls is even. Find the following sets: BC , A ∩ B, A ∪ C, A ∩ C, (A ∩ C)C , A ∩ (B ∩ C)C , (A ∩ (B ∩ C))C ? BC = C, A ∩ B = A \ {2}, A ∪ C = Ω \ {9, 15}, A ∩ C = {2}, (A ∩ C)C =Ω \ {2}, A ∩ (B ∩ C)C = A, and (A ∩ (B ∩ C))C = Ω.
