The issues with violations of the privacy In the essay “Privacy Under Attack”‚ the authors explains that people in today’s society are experiencing violation of their privacy by the government‚ the companies‚ and the criminals.The authors explains that criminals are not only people who would violate our privacy. They explained that the government would violate the citizens privacy for citizens’ safety by usage of surveillance cameras all over the place. The government is using these to find out about

Earth’s Energy Budget Introduction: This Albedo lab was created to help explain the process in which the Earth reflects solar energy back to space. The fraction of radiation reflected by an object is known as an albedo. In relation to the atmosphere‚ as solar radiation reaches certain colors on the surface of Earth‚ more radiation is absorbed by darker colors‚ which in turn decreases the solar radiation that reflects back to the atmosphere. If a person was interested in learning more

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

the Plasma Membrane i. We mixed 5 ml of water and cooking oil into a test tube by shaking it. Then we observed the mixture as it settles for five minutes. We shook the test tube again and took a sample into a slide before it settled. We observed it under the LPO of the compound microscope. ii. We placed cooking oil into a Petri dish‚ and dropped an egg solution into it. We observed it for a formation of a membrane‚ then puncturing it. iii. We placed the evaporated milk in a beaker until it is ¾ full

Period 12 Chemical Aspects of Life & Spit Lab ABSTRACT: The objective for the Spit lab was to test two different types of crackers for the presence or absence of starch and of reducing sugars. Also‚ to test the chewed cracker‚ the one that didn’t have a reducing sugar‚ for the presence or absence of a reducing sugar with the saliva in it. Adding on‚ another part of the objective is to determine the effect of amylase on starch. For the Chemical Aspects lab‚ the objectives were to test for the presence
