Jennifer Nelson Unit 3 Assignment 1 Date due: July 12 Date submitted: July 12 Define Key Terms Electrical circuit: A complete loop of material that conducts electricity. Frequency: When describing energy that acts like waves‚ the number of times that the entire waveform repeats per second. Amplitude: When describing energy that acts like waves‚ when graphing the waveform centered on the X axis‚ and graphing some kind of power (for example‚ voltage) on the Y axis‚ the amplitude is the maximum

Assignment Week 4 Chapter 11 20. A parallel RL circuit has values of IL = 240 mA and IR = 180 mA. Calculate the magnitude and phase angle of the circuit current. It=√ IL^2 + IR^2= √ 240mA^2 + 180mA^2= 0.3 x 10^-3= 300mA θ= tan^-1(-IL/IR)= (-240mA/180mA)= -53° 300mA∟-53° 22. Calculate the total impedance for the circuit shown in Figure 11.38b. It= √IL^2 + IR^2= √800mA^2 + 120mA^2= 0.808949 x 10^-3= 808.95mA Zt= Vs/It= 120V/808.95mA = 148Ω θ= tan^-1(-IL/IR)= (-800mA/120mA)= -81.5= 82° 148∟82° 24

I’m hoping to investigate how magnetism works through different types of substances. I chose two unique substances to test magnetism through: slime and wood. I hypothesize that magnets can still work through slime and that they can work through wood‚ but I hypothesize that they can’t work through both‚ because the magnetic field will be blocked too much. I designed five different set-ups to test how the magnets react in different ways using these materials. The results of the experiment proved four

In this lab‚ we are measuring the EMG amp (mV)‚ or electrical activity‚ from action potentials produced from muscle contractions in order to gain an indication of the number of active motor units used in the contraction. This is done by adding more load to the muscle or force. There is examining of the EMG amp produced from a twitch at varying levels of muscle force and EMG amp from muscles when more load is placed on them. During the experiment‚ we set up the equipment‚ electrodes and software

Why Should One Be Electrically Trained? This is a very obvious question in many people mind that why one needs to be electrically trained. We thought if we find any sort of electrical problem we simply call some commercial electrician in Sydney or electrician in Castlehill. Although this is the best thing one should but still electrically trained person can not only protect himself from getting harmed by some electrical equipment also able to manage the situation in case of some electrical hazard

String theory is defined by Merriam-Webster as‚ "A physical theory in which one-dimensional loops travel through space and also merge and lyse as time elapses. This is in contrast to ordinary quantum field theory‚ which predicts point particles that emit and absorb each other. String theory is a candidate for a Theory of Everything." String theory would solve the long fight between Einstein’s theory of relativity and Quantum Physics. String theory proclaims that everything in our universe‚ from

A variety of representations were used to represent subject matter. Words such as “words”‚ “pictures” and “artefacts” within the concept map suggests that both textual and visual representations would be used during instruction to promote conceptual understanding of the topic. The inclusion of apparatus such as magnets‚ coils and galvanometers in the concept maps suggests that scientific tools would be used as forms of representations to transform subject matter knowledge into knowledge suitable

André-Marie Ampère‚ a French physicist and mathematician‚ founded electromagnetism‚ which he called electrodynamics. He was born in Lyon‚ France during the French Enlightenment‚ on January 20‚ 1775. His father‚ Jean-Jacques Ampère‚ and mother‚ Jeanne Antoinette Desutières-Sarcey Ampère‚ believed André’s education should be without formal schooling‚ and allowed him to teach himself with their library. When he was twelve‚ he was able to teach himself advanced mathematics because of his access to books

opening new avenues of research in areas such as mathematics and philosophy. Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. For example‚ advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products which have dramatically transformed modern-day society‚ such as television‚ computers‚ domestic appliances‚ and nuclear weapons; advances in thermodynamics led to the development
