Laser welding is a technique in which a tightly focused laser beam is used to deposit enough energy to weld metal parts together. Because the entire process can be automated, it is commonly used in many large-scale industries, including the manufacture of automobiles. In order to achieve the desired weld quality, a particular pair of steel parts being joined must absorb energy at a rate of about 1.1 x 104 W/mm². A common laser welding system employs a Nd:YAG laser operating at a wavelength of 1.064 µm. At this wavelength, this particular set of steel parts will absorb about 80.% of the incident photons. If the laser beam is focused to illuminate a circular spot with a diameter of 0.020 in, what is the minimum power (in watts) that the laser must emit to reach the 1.1 × 104 W/mm² threshold? (Recall that 1 W = 1 J/s.) W How many photons per second does this correspond to? (For simplicity, assume that the energy from the laser does not penetrate into the metal to any significant depth.)

女大考三題型 Unit 8 The Risks of Bio-terrorism In 2001 a number of US government employees and citizens died, after opening 1 letters deliberately contaminated with a deadly disease. 2 The government has responded to the threat by introducing a "Bio-Watch" system, which uses special equipment to detect unusual organisms in the atmosphere. Nevertheless, it can provide an early warning system for major towns and cities, allowing medicine to be rushed to an area under attack. 3 However, the US government is much more worried about the psychological impact, rather than the actual death toll, of a bio-terrorist attack. Any disease effectively released as a bio-weapon in a highly populated zone could cause general panic. 4 As a result of the continuing bio-terror threat, the US government is trying to make its citizens more confident that it can combat this menace. By doing so, it hopes that there will be less widespread panic. Therefore, if a major bio-attack occurs, people can take immediate action to minimize the damage. (A) This was probably the work of a mad scientist, but it signaled to all Americans that bio-terrorism was a clear and present danger. (B) This might freeze normal economic activities in the world's biggest economy center, and thus cause chaos in the global financial system. (C/Infected people can then be treated, and most will survive. DUnfortunately, this technology cannot filter the mail or prevent terrorists releasing diseases in enclosed places. 1. 2. y 3. C 4.

A Unit 1 8 Environment The Melting Ice Caps The world's ice is melting, and it is happening at an alarming speed, rate, 3 Global warming has been increasing at a very unsustainable² and the polar ice caps have been vanishing³ before our eyes. In the 55 years between 1961 and 2016, the Earth's total ice loss amounted to an estimated nine trillion³ tons. The start of the 21st century bore witness to several profound decreases in terms of the area covered annually by Arctic ice. The year 2012 was the lowest on record, while 2007, 2016, and 2019 were tied for second-lowest. 10 As the ice melts, an excessive amount of melted water emerges from it. This large amount of melted water manifests itself as a rise in sea levels. (This rise leads to the increased erosion -or wearing away- of the coast. When combined with the higher frequency of ecological" disasters¹2, it results in a bigger storm surge¹3. Climate change threatens¹4 15 to forever change the way we live.
