An object was placed or hanged on the proper area, where it could sit at rest. That is to say an inclined track for the cart, and a ring stand for both the pendulum and a mass attached at the end of a spring. Hereafter, a motion detector was connected to a computer via a lab quest and was brought in close proximity with the object. After that, the motion detector sensitivity switch was set to ball/walk or track depending on the object’s motion which is being studied. From here, the appropriate file for plotting an object’s graphs was opened on the desktop. Then, from here, everything was in place for data collection. (Photos below).

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, familiar numbers. So long as every distance within the system of interest is scaled by the same

This paper comprises an appreciation of data representation, its visualization, an outline description of behavior, plus an indication of the use of the equation in engineering.

1. Objective: My objective for this experiment is to find the mass, volume, and density of a variety of objects. After this, I will record my data and place a select few of the items on a graph. My hypothesis for this experiment is, "If I measure the mass of every object, the wooden ball will have the least because it seems to be the smallest and most lightweight. " 2.

The Grignard reaction is an important synthetic process by which a new carbon to carbon bond is formed. Magnesium metal is first reacted with an organic halide forming the Grignard reagent. The Grignard reaction is the addition of an organomagnesium halide (Grignard reagent) to a ketone or aldehyde, to form a tertiary or secondary alcohol, respectively. For example, the reaction with formaldehyde leads to a primary alcohol. Grignard Reagents are also used in the following important reactions: The addition of an excess of a Grignard reagent to an ester or lactone gives a tertiary alcohol in which two alkyl groups are the same, and the addition of a

This lab has a very interesting and impactful goal of developing a genotoxicity biosensor using GFP. Genotoxicity and mutagenicity is simply when there is something that can cause a mutation in DNA and it is usually caused by chemical genatoxins or radiation. The reason this is important to consider is because genatoxins can be carcinogenic, meaning cancer causing, and obviously that is very dangerous. Cancer is still something we have not been able to find a cure for, so any advancement we can find can help us better prevent or come closer to curing cancer. By studying this we can potentially create a biosensor that can tell us and warn us of chemicals or radiation that is causing cancer. There are currently two tests that exist for

The speed of an object is related to the shape of a graph because depending on whether the speed varies during the motion or remains constant, the graph’s shape will be affected. If the speed of the graph remains the same (uniform) the shape of the graph will be linear. If the speed of the object varies (non-uniform), the graph will have variations in the data for the position which depends on the slowing down and speeding up of the object, leaving us with the outcome of a curve of best fit or a parabola shape. The graph will be in the form of a non-linear shape. The speed of an object’s motion on the graph represents the slope of the graph. A linear graph with straight

This review of literature discuss the main terms,and ideas related to the experiment conducted,and seeks an explanation on why it happen. The topic will cover kinetic energy, gravity,velocity, and force of impact. Even if we know the process of conservation of energy to an object that is falling allowing us to predict its impact velocity, as well as the kinetic energy. However we cannot predict the impact force without knowing how far it will travel after impact.

The line of best fit for Resistor 1 (Graph 1) had the steepest slope. The slope in this graph represents resistance, as resistance can be calculated as voltage over current. Slope is the change in the y-axis (voltage) over the change in the x-axis (current). Since Resistor 1 had the greatest change in voltage over the greatest change in current, it had the largest slope.

Third graph has a horizontal line, what does this mean in context of the given condition? Why do you think it is below zero?

The experiment, performed earlier by a first grader, consisted of a ball rolling down a ramp. Each time the initial height of the ball increased, and the ball was rolled down to measure the distance (in inches) it travelled. The assigned task asked to produce a mathematical relationship between the initial heights of the ramp to the distance the ball rolled (a slope)—the data presented exhibits this relationship.

The line of best-fit is used to find the gradient, the T2/L value, if straight or linear it shows that the relationship between the two is directly proportional. Using the original equation, you can square both sides and rearrange it to make . Then you can input the gradient value (T2/L) and work out g. , where g equals 10.13 m/s2. This value is close to the

For this CER, I chose to answer question #1; How does the contact force between ball “a” and the magnet cause ball “e” to fly off the end of the cannon? The contact force between ball “a” and the magnet causes ball “e” to fly off the end of the cannon because of the transformation of the kinetic energy of ball “a” into elastic energy that travels through the system and then gets transformed back into kinetic energy for ball “e”.

Theory states that T and d are related by the equation: T2 = kd3+ (4π2 l)/g where g is the acceleration of free fall and k is a constant.
