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

ROA‚ ANNA MARIA D. BA PSYCHOLOGY 1 Physics and Psychology—Relationship Status: It’s Complicated but Related One way or another‚ all things in life are related to one another. The same goes with Physics and Psychology. These two Sciences are different in a lot of ways but are also similar in certain aspects. Physics is the branch of Science concerned with the nature and properties of matter and energy. Psychology‚ on the other hand‚ is the scientific study of the mind and its functions

Over the past few years‚ environmental issues have become increasingly more important‚ not only as an ecological concern lead by activists but as an economic matter lead by business savvy individuals. For many corporations the green movement can translate directly into increased efficiency and therefore increased profits. Flextronics for example has found a way to refurbish their own products‚ Motorolla cell phones‚ to optimize resource use and profits. This comes after the realization that their

I excelled and that I can be proud of and yet‚ hidden deep in the files of my educational life‚ I can see moments where I messed up. Only later on did I recognize that I could have done better. One such moment occurred recently‚ in junior year‚ when I almost failed Pre-Calculus. Academically‚ I have always been strong. Teacher assigns an essay on the symbolic values of the color green? No problem. Physics lab report due the next day? I’ll get it done. Using scalar multiplication to do something

Introduction of Physics: Physics ("knowledge of nature") is the science concerned with the discovery and understanding of the most basic fundamental laws of the universe that control the way everything in the world around us behaves. Discoveries in basic physics have important ramifications for all of science. Physics attempts to describe the natural world by the application of logic scientific methods‚ including modeling by theoreticians. As a core scientific discipline‚ physics is concerned with

Calculus: Calculus (Latin‚ calculus‚ a small stone used for counting) is a branch of mathematics focused on limits‚ functions‚ derivatives‚ integrals‚ and infinite series. This subject constitutes a major part of modern mathematics education. It has two major branches‚ Differential Calculus and Integral Calculus‚ which are related by the fundamental theorem of calculus. Calculus is the study of change‚ in the same way that geometry is the study of shape and algebra is the study of operations
