In order for this equipment to assist one in measuring the speed of sound, the speaker and microphone are positioned inside the hollow tube with the speaker stationary at one end. The microphone is able to be moved and set a chosen distance from the speaker, from almost touching to 1 meter. The signal generator is connected to the speaker by a pair of wires. From this pair of wires, another pair of wires connects the signal generator to the frequency meter. A set of wires also run from the signal generator to the oscilloscope. A separate set of wires is connected from the oscilloscope to the microphone inside the tube. The set up of the equipment allows for the output of the signal meter to be read and measured by the frequency meter while being led to the speaker. This input causes the speaker to vibrate, which produces sound waves inside the tube. These sound waves, picked up by the microphone, are then sent to the oscilloscope as a signal. A pattern is displayed on the screen of the oscilloscope. With the signals in phase, the patterned displayed is a straight diagonal line. With…
2. If you double the current through an inductor, the energy stored in the associated magnetic field increases by a factor of _____.…

The main focused purpose of this organization structure paper is to select two organizations such as Facebook and MySpace. I will compare and contrast the differences of their organizational structures. I will also address and evaluate their organizational functions that made and determined their organizational structures. I will elaborate and explain their organizational design and how these organizations have influenced society especially in the social media world. As we all know today modern world, every single person has either a Facebook or MySpace account and spend numerous hours online talking, chatting, socializing, staying connected to friends and families, and networking with other work related colleagues or school projects. This has tremendously enhanced communication effectiveness and time limitation.…
Some important past research conducted by other people includes the creator of the project, Annie Lefley. Annie created this project to see how much tension is put on the patellar tendon when grande pile or a demi pile, two moves in ballet. She used the mechanical model, which resembled a knee, featuring the hip, the patella, the femur, and the tibia/fibula. Also included in the model, is a guitar string and a guitar tuning mechanism. These resemble the ligaments in the knee. Whenever you turn the tuning mechanism it will move the knee while putting tension on it as it bends.…

A 10-kg bowling ball moving at 4 m/s bounces off a spring at about the same speed that it had before bouncing. What is the change in momentum of the bowling ball?…
Increasing space between each domino will decrease its velocity, decreasing the space will increase its velocity. Force at which it hits next dominoes is increased it will take longer for it hit, acceleration is constant, the longer it has to travel, the longer it will take to hit.…
What is the price elasticity of demand for widgets between $8 and $10? . What is the elasticity of demand between $2 and $4? . As price decreases, demand becomes more / less elastic. What is total revenue per month at a price of $4? . A reduction in price from $4 to $2 causes total revenue to…

The poem “Cartoon Physics” by Nick Flynn is about kids being kids and the importance of never forgetting how to be a kid at heart. The path we take in life as an adult takes us far away from what we once were when we were kids, however, it is important to never lose the kid in you.…
Graphs and charts are common tools used in science. To interpret graphs, read the axis labels as well as the numbers on the axis. The title should give you some clue as to the purpose of the graph. Next, examine the content. Try to describe the content in words, using “As ____(quantity on the x axis), ____(type of change, such as increases or decreases), ____ (quantity on the y axis) ___(type of change such as increases or decreases).” For example, the graph above could be described, “As time increases from 0 to 8 seconds, the velocity of Billy increases linearly from 0 to about 14 m/s.”…
Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water, but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing its temperature, the energy is used in breaking bonds in the structure of the material while changing state.…
On Monday 8th October our physics class went on a physics trip to Thorpe Park to look at the different ways in which a roller coast works. This report will be looking at the G forces acting on rides, the launching systems and breaking systems. The particular rollercoaster which I have picked to look into more detail in is “Stealth” which is located in Thorpe Park.…
