The stone played an important role in the development of human life from ancient times. The stone is omnipresent and it is never given much importance. It has its role in technology, science and politics. (Hass,2008) Hass gives the example of a hammer in order to give an example of the use of stones in technology. Hass says that the stone-age hammer is now begin changes to steel hammer but the idea and the purpose remain the same .Hass(2208) support this key point of science by saying that “stone have taught us the shift in magnetic poles, and where to look for oil and metals”(p.57).Hass gives the use of the stone in politics; war, in metallurgy and in modern technology.
Timing – synchronization between devices that are communicating so that they each know when the patterns start and end. If one of these elements is not present than communication cannot be established between devices and information cannot be transmitted. Exercise 2.1.2 Characteristics of a modern computer that allow this type of integration is advancement in circuitry that allow it to be installed on the computer as one device or unit. Exercise 2.1.3 Other network services available for installation are UPnP user interface and TCP/IP services Exercise 2.1.4 Since there are no physical connections everything can be done wirelessly. Exercise 2.1.5 The types of connections that are available are wired connection, wireless connection, and dial-up connection.
Suwat Charoenrut 5280753 Analyzing artifact: the Baghdad battery During many excavations and archeological digs, numerous uncovered artifacts have created a new way of looking at the technological strides associated with ancient civilizations. In this article, you will learn of metal objects that have appeared in the oddest places, as well as what seems to be the first battery, dating more than 2,000 years old. 65 million years ago, humans were not roaming the world, so why is it that a semi-ovoid metallic tube was found within chalk that was dated at being 65 million years old. Discovered in France, this find hailed from the Cretaceous period. The Cretaceous period was the third and last block of geologic time during the Mesozoic
Task 1 p3 & p4: Task 3 D2: Since the information is encoded differently in analogue and digital electronics, the way they process a signal is consequently different. All operations that can be performed on an analogue signal such as amplification, filtering, limiting, and others, can also be duplicated in the digital domain. Every digital circuit is also an analogue circuit, in that the behaviour of any digital circuit can be explained using the rules of analogue circuits. The first electronic devices invented and mass produced were analogue. The use of microelectronics has reduced the cost of digital techniques and now makes digital methods feasible and cost-effective such as in the field of human-machine communication by voice.
This table shows the magnitude found when using the rheostat portion of the experiment. Trial 4 V (v) | I (A) | 2.0 | .02 | 4.0 | .04 | 6.0 | .06 | 8.0 | .08 | 10.0 | 0.1 | 12.0 | 0.12 | 14.0 | 0.14 | 16.0 | 0.16 | 18.0 | 0.18 | 20.0 | 0.20 | Table 4. This table shows the magnitude found when using the Unknown resistor portion of the experiment. In order to find the data from the above tables, my partners and I

Maddux III. and Harry Gene Redden, Sam Houston State University “I think I’ve found what I’m looking for,” Gary Roberts said. “Oh yeah, what is that?” Jim Handley asked, as he handed Roberts a pair of vice grip pliers. “I’m thinking I might have found a way out of this dump. No more tile dust, no more forty-mile an hour winds blowing through the plant, and no more Al Wright for me”, Roberts replied.
Explain how you determined this. Pyrite hypothesis accept/reject = I would reject as there was no change. Coal hypothesis accept/reject = I would accept as ph was indeed higher Based on your data, what effect do you predict coal mining has on the environment? Answer = I would say coal mining increases acidity in the environment. What can be done to prevent mine drainage from damaging the ecosystem?
Coal (activated carbon) hypothesis = If coal is added to water, then the water will become more acidic. 2. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this. a. Pyrite hypothesis accept/reject = I rejected my hypothesis because there was no change in the pH levels after testing with a pH strip.
The first inaccuracy comes from before the film even begins. K-19: The Widowmaker is mostly based on the nuclear meltdown of the submarine's core and the subsequent explosion that is avoided. The misconception with that, however, is that a nuclear meltdown alone will not cause a thermo-nuclear explosion (Kirby, 230). This causes a question to come to mind. What is the necessity for this change?
CIS 105 Week 3 DQS CIS 105 DQ 1 There are a variety of computers available, from the smallest computer in a domestic device to the supercomputers used in industry. Despite the different uses for computers, they all have basics elements in common—each computer system involves hardware, software, data, and users. Think about the role of each component of your home or work computer: How do the components of your computer system interact within the system? What improvements or additions to your system do you think would benefit you or make the system more user-friendly?
