The theory of personal space proposes that you and I feel uncomfortable when others get too close in certain situations. This discomfort can‚ says the theory‚ be measured by increased heart rate‚ blood pressure or skin perspiration. The research problem is that to measure these things we have to hook a subject up to some device‚ and they thus know they are being studied. Their behavior might not be natural. To test the theory and solve this problem‚ the following was done: A study by Middlemist

The local media‚ especially the local dailies‚ have been replete with reports of snatch thefts. The barrage of media reports has caused more than a sense of anxiety‚ it has caused fear and panic among residents. Recently‚ there has been a spate of snatch thefts in our area. Snatch thefts tend to escalate during festive seasons and holidays. Hotspots of snatch thefts are quiet and deserted areas such as residential areas‚ by the roadside‚ in lifts and around the bank. Snatch thieves choose their

salt. Post Lab Questions and Answers: 1. In parts A and B in‚ the calorimeter‚ although a good insulator‚ absorbs some heat when the system is above room temperature. Is the reported value for the specific heat of the metal too high or too low? Explain. Is the reported DeltaHn value for the acid- base reaction too high or too low? Explain. The DeltaHn value reported in Part B will be lower than the true value because the true Delta T will never be reached. Since the calorimeter absorbs some

Evaluate and Solve Common Security-Related Problems Introduction Guidelines: It’s always best to introduce a paper to the reader. It sets the tone and provides an overview of what will be covered and what the goals are. • What is the intent of the lab? What issues are addressed? Why is it important? What are the goals? Specific questions from iLab Guidelines: Minimum one paragraph; best practice is two or more paragraphs. Always use complete college-level sentences. Scenario 1 1. Discuss how

Hess’s Law. Pre-lab Questions: 1. Define Heat of Reaction. The enthalpy change associated with the completion of a chemical reaction. 2. Define Specific Heat. The energy it takes to raise the temperature of 1 gram of a substance by one degree Celsius. 3. Calculate the heat of reaction assuming no heat is lost to the calorimeter. Use correct significant figures. Q = c x m x t q = (4.18)(1.02 g/ml x 50ml )(3.9 oC) = -831 J 4. In problem 3 above‚ the calorimeter has a heat capacity

A new drug has been formulated to reduce hyperactivity for children ages 5-17. To test this I will be using 100 children that are randomly selected clinically labeled hyperactive child. 50 Children will be randomly assigned to the experimental group and the others will be placed in the control group. Both groups however will be told that they are being given the new drug (a single – blind study). The experimental group will be given the drug and will be asked to meet every day for two hours‚

Lesson 1.06 1) Explain the relationship between continental drift and the formation of the Earth’s Oceans? -The relationship between continental drift and the formation of the Earth’s Oceans stems from plate movement that occurred on Earth. There is a theory that all the continents were once all one big piece of land named Pangaea‚ and over millions and millions of years the land of Pangaea started to split apart into many different continents. It divided Panthalassa‚ the large global ocean that
