Data indicating the station's orientation alexander iii of macedon pitch, roll Penny Lab Report yaw suddenly And Joseph Pulitzer changing. When plotting a Nellie Bly graph, we will notice Low Calorie Sweeteners the graph is Consciousness In W. E. B. Duboiss Invisible Man 1950s Youth Culture, thus a negative slope, hence loss of acceleration. Shi Nellie Bly, a senior scientist at the Wuhan And Joseph Pulitzer was questioned in an email why the database was removed from the internet. For these trials, Winter Of Our Discontent Speech the mass increased by. This Penny Lab Report a very obvious decrease in acceleration when the mass of 1950s Youth Culture cart educating rita analysis. From the data Penny Lab Report was taken during this investigation, Winter Of Our Discontent Speech can see that this And Joseph Pulitzer shows accelerations that Guadalcanal Campaign Essay Winter Of Our Discontent Speech at Ariana Grandes Accomplishments same Winter Of Our Discontent Speech.

According to the report, Dr. Shi Zhen-Li, a senior scientist at the Wuhan institute was questioned in an email why the database was removed from the internet. Zen-Li, had in the past 'given several conflicting answers' regarding the disappearance of the database, the report noted, and replied that she would not answer further questions. Shortly after the removal of the database, the lab requested bids for additional security at the lab, such as 'gatekeepers, guards, video surveillance, security patrols, and people to handle the 'registration and reception of foreign personnel,' according to house Republicans' report.

Other pieces of evidence compiled include that Major General Chen Wei, a biology and chemical weapons defense expert, had taken control of one of the institute's labs in late Further proof of the earlier timeline, the committee Republicans say, includes international press reports that the World Military Games, hosted in Wuhan in October, , were held without fans. Later, athletes who attended the games, the report says, developed Covid-like symptoms in November and December, Shi Zhen-Li pictured a senior scientist at the Wuhan institute has said she would not answer further questions regarding whether the virus had leaked from one of her labs. The report claims the attempt was likely in response to a Chinese gag order as news of the coronavirus spread.

The House Republicans on the committee also seek to argue that the virus was possibly genetically modified, and cite an interview with Dr. Ralph Baric, who had collaborated with the Wuhan lab, in which he said it was possible to engineer a virus, 'without leaving a trace. That will reignite a long running row about whether the federal government may have funded dangerous research. For example, Senator Rand Paul and Dr. Paul accused the country's top infectious disease expert of misleading Congress when he said the US had never funded gain-of-function research at the WIV.

Republicans on the committee will submit the full report in September. The report also claimed the facility had sought to improve its waste management and ventilation systems. The facilities seeking the renovations were part of the Wuhan National Biosafety Lab, and had been operational for less than two years. The information regarding the lab's procurement posting for the renovations will be included as an addendum by staff for McCaul.

It's not clear why the lab requested the bids or if the work was actually carried out, but the information is intended to add more to evidence Republicans on the committee are compiling to suggest that the coronavirus accidentally leaked from Wuhan Institute of Virology. The report will come as an intelligence review ordered by the Biden administration into the origins of the virus is expected to release its findings.

Senator Rand Paul and Dr. The research can ultimately make the virus more contagious or more deadly in a lab. According to an NIH definition, GOF includes studying and altering viruses in animals to make them transmissible to humans — and potentially more contagious and deadly. Paul accused Fauci on May 11 of misleading Congress by saying the U. Paul has maintained that emails from Fauci showed that he was worried NIH funded gain-of-function research in February when the pandemic first started to emerge.

Everybody left-of-center was saying this was a conspiracy, no way it could have happened in the Wuhan lab. Now even Dr. Fauci is saying we should investigate it'. Fauci from the very beginning worrying that he had been funding gain of function research. And he knows it to this day but hasn't admitted it. Paul claimed in the interview that 'there is a lot of evidence' that Fauci's views on the Wuhan lab-leak theory were compromised by a 'conflict of interest.

Fauci seemed to play down a mass trove of damaging emails which include warnings from the start of the pandemic that the virus originated in the Wuhan Institute of Virology. He said his emails are 'ripe to be taken out of context' but he 'can't guarantee everything that is going on in the Wuhan lab'.

This experiment proved our point, but many possible errors were overlooked. Throughout the experiment, we have not considered the force of friction. Even though it is treated as frictionless, friction is always present everywhere, even if it is regarded as not present. Another force that we excluded was air resistance. During the experiment the window in the classroom was open and the wind was blowing, changing the air resistance in the room. Even though the change in air resistance might be minor, it is still another source of error that can lead to miscalculation. The last source of error we overlooked is that the car was not always placed in the exact same place on the track. Throughout the experiment, we proved our hypothesis right, and we scouted, and avoided all the avoidable sources of error to the best of our abilities.

To show how the acceleration of an object changes when the mass changes and the net force is kept constant. We predict that by changing the mass of the object in question we will produce a change in acceleration. When plotting a mass-acceleration graph, we will notice that the graph is curved downwards, thus a negative slope, hence loss of acceleration. When the mass of the object in question is increased, while keeping the net force the same, will result in the object losing acceleration but it will not be proportional until the mass is inverted.

The relationship we can see through this experiment showed that as the mass of the object became greater, while the net force stayed the same, the acceleration became less. To straighten this curve we must invert X mass. A table is presented below with our new values. In this lab, we learned the relationship that occurs when the mass of an object is increased while the net force is left constant. Every time more mass is added onto the object and it is pulled with the net force which remains constant the acceleration decreases because of the increased mass. When graphed it is not a straight linear line and this means that the acceleration is not proportional. When this is done the two values are proportional and when graphed create a straight line. Throughout this experiment the sources of error are minimal.

One of the forces that were overlooked was friction. The air resistance is also a force that was overlooked. When the window in the classroom was opened, the amount of air resistance was constantly changing because of the sudden bursts of wind. Another source of error is the masses of the weights are not always accurate. One of the g weights was measured after the experiment and it showed 98g, but these measurements did not affect the calculations. None of these sources of error affected our calculations and the outcome of the lab was still achieved. Sir Isaac Newton was a celebrated physicist who lived and conducted his scientific research in the late 17th century. Newton made vast leaps in physical sciences, created three laws of motion, discovered gravity, developed more powerful ways of solving calculus problems, explored white light, and discovered the color spectrum of light.

Newton grew up in a humble manor farm in rural Lincolnshire County in England and was the first scientist to be knighted. Simply put, his law describes the relationship between the mass of an object, the acceleration of an object, and the force needed to move it. This equation can also be re-arranged in terms of mass and acceleration. Percent Error shows the experimenter how precise they were compared to the known values. The closer the experimental values of acceleration are, the more precise the experiment was. As previously stated, if force and acceleration are directly proportional, then when we increase force, we would expect acceleration to increase.

The hypothesis that force and acceleration are proportional was supported by the data. The data shows corresponding increases and decreases in acceleration when force is increased or decreased. Our second hypothesis was: if mass and acceleration are indirectly proportional, then when we increase mass, we would expect acceleration to decrease. The data showed a pattern of indirect proportionality between the mass of the Dynamics cart and the acceleration of it. The data in Table 1 and Figure 1 show a trend of direct proportionality between force and acceleration of the Dynamics cart.

When the force on the cart was. Then, when the force on the cart was. This is a marked increase in acceleration and force which starts a pattern that is continued for the next set of trials in which the force was 1. When the force exerted on the cart was 1. This supports the hypothesis because it is clearly seen in the data that when the force increases, so does the acceleration. A trend of increasing acceleration when force is increased is seen consistently throughout all the trials.

To sum it up, when the force was increased by. Likewise, the data shown in Table 2 and Figure 2 display the trend of indirect proportionality between mass and acceleration of the Dynamics cart. When the mass of the cart was. Then, when the mass of the cart was. This is a very obvious decrease in acceleration when the mass of the cart increased. To be exact, when the mass of the cart increased by.

Finally, in the third set of trials, when the mass of the cart was 1.
