TUBERCULOSIS Tuberculosis‚ commonly known as TB‚ is a contagious and an often severe airborne disease caused by a bacterial infection. TB typically affects the lungs‚ but it also may affect any other organ of the body. It is usually treated with a regimen of drugs taken for 6 months to 2 years‚ depending on the type of infection Tuberculosis was popularly known as consumption for a long time. Scientists know it as an infection caused by M. tuberculosis. In 1882‚ the microbiologist Robert Koch discovered

Week #7 Chapter 10 Static and Current Electricity Exercises (p.221) 6. Strictly speaking‚ will a penny be slightly more massive if it has a negative charge or a positive charge? Explain. A negative charge because when it is negatively charged electrons are added to the penny. 17. What is the voltage at the location of a 0.0001 C charge that has an electric potential energy of 0.5 J (both voltage and potential relative to the same reference point)? Potential = energy Charge = 0.5 J / 0.0001

HG-1 THE HEAT OF FUSION OF ICE Introduction When heat flows into a system there are a number of things that can happen. One result could be a temperature rise. Or‚ the system might even catch fire. A third possibility is a change of state. As you know‚ matter exists in three states (or maybe four‚ the fourth being a plasma)‚ solid‚ liquid and gaseous. At different temperatures‚ the same substance may be in different states. Each state is characterized by the way the interatomic forces act. In solids

1. Properties of light Reflection The speed of light is measured through the equation: v = λ f. However‚ it turns out that when light is reflected off a surface its speed stays the same. This was first proven by Sir Isaac Newton. Under the assumption of perfectly elastic collision‚ the laws of reflection follow from the laws of motion. To demonstrate‚ consider a particle traveling towards a flat frictionless surface whose horizontal and vertical velocity components are: VX and VY. When the particle

Murphy Grand Canyon University: Physics 1 Lab September 5‚ 2013 Testable Question: Circular objects; what happens to the circumference as the diameter changes? Hypothesis: As the diameter increases‚ the circumference will increase in a proportional linear way. This is because as the diameter increase‚ the object will as well. Variables: Independent- The diameter of the circular objects. Dependent- The circumference of the
