1. Wireless charging seems like an incredible new technology - instead of having to plug in your phone or electric toothbrush, you can just put it on top of a base (which is plugged into the wall) and it will charge wirelessly. But in fact the principle behind this technology has been known for over 100 years. Identify which big law that we learned in PHY 212 explains how wireless charging works, and speculate about what you would find if you opened up a wireless charger and looked inside.
2. A generator is running, providing power to a few different appliances at the moment, when someone flips a light switch so that an additional light is now being powered by the generator. The generator's rpms don't change even though it is now powering an additional load. If not the rpms, then what has actually changed about the generator? Where is that extra power coming from?
3. Consider this circuit. In case there is a problem, here is the description: resistor B and a switch are in parallel, and this parallel combination is connected in series with a battery and with resistor A. The switch is now open.
When the switch is closed, please describe what happens to each of the three quantities and why. The choices are increase, decrease, or stay the same, but be sure also to explain why each happens.
a) current through A
b) current through B
c) total power output by the battery
4. A wire coil that encloses an area of 180 cm2 and has 250 turns spins within a uniform 0.33 Tesla magnetic field at a rate of 600 rpm. What is the amplitude of the emf, in volts, induced in this loop?
5. An electron, starting at rest, is accelerated through a potential difference equal to 953 V. What is its final speed, in m/s?

When technology spillover occurs,
Select one:
a. it is the government's responsibility to own firms that are engaged in high-tech research.
b. a firm's research yields technological knowledge that can then be used by society as a whole.
c. those firms engaged in technology research should be taxed by the government.
d. firms invest in the latest production technology and the cost of that technology "spills over" to the prices consumers must pay for the product.

Introduction
Author Beaufort Longest notes “A third type of resource that health policies significantly affect is health related technology.” He goes on to discuss how funding and regulatory policies have shaped the use of technology. In addition, remember that technology is a driving force behind accessibility of data.
Instructions
Using Longest’s thoughts on technology, the weekly readings from the course text, and the Hu et al. article as the basis for your thoughts, explain how using technology (especially health informatics) is not only affected by but also affects health policy.

Pick one Hype Cycle (Gartner publishes many Hype Cycle for variety of technology groups) that interests you the most. Pick the version that is quite recent, not too outdated. And pick one of the technology (sub-technology) plotted on that curve, and explain: - Why does this sub-technology interest you? What can it do for you, or for your community, or for your world?
- Is there already a standard or dominant design for this technology? If yes, what it is. If not, what do think the dominant design will look like? Briefly explain (in either case), why it can (or has) become the dominant design, e.g. what are its critical/killing features, etc.
- If you are to introduce a product or service in this technology category, when would be the "right" time to debut your product. Provide reasons to support your decision.

A side-venture Jane is an inventor, working for the ACME Gadget Company in research and development. She recently proposed the development of an advanced technology, but it was deemed too risky for R&D at ACME. However, ACME has agreed that if Jane successfully develops the technology on her own, ACME will acquire a license to use the technology for a period of 10 years. To develop the technology will require an initial expenditure of $150,000 and an additional expenditure of $150,000 at the end of each of the next 2 years. When the patent is approved in Year 4, it is expected to be licensed to the ACME Gadget Company for an upfront fee of 100,000 plus an additional fee of $90,000/year for 10 years. At that time the product that uses the technology will be replaced by a new model. What is the rate of return on the Jane’s advanced technology?

Dell started from humble beginnings. Like many big technology companies such as Apple and Microsoft; Dell was started by a college student. Michael Dell’s idea of building computers to order was a brilliant one that became lucrative. Nowadays, computers are now mainly utilized by businesses and hobbyists, everyone is using them. Dell managed to remain at the forefront in the technology industry by investing in people, betting on technology to guide and shape its future and by emphasizing its culture. However, Dell has changed by doubling down on its efforts and transforming itself along the way. It has gone public again but when it was private, the tech company heavily invested in expansion of its product line by selling software, hardware and data center services. In fact, Dell spent $67 billion for EMC, a storage hardware company. This was a record-breaking deal which helped Dell sustained slow growth for personal computers. However, since then, Dell decided to go public again, in a strong position, with a buy-back price of $120 per share for a grand total of $23.9 billion, to enable the company to grow stronger and simplify the ownership structure. Dell is continuing to spend money on information technology; however, the company is trending towards taking advantage of cloud computing services from companies like Salesforce and Amazon rather than building new data centers to host business applications.
I believe that for a person playing the speculative trade would have fared well during the time Dell went private because the company has always been a in a good position to grow and shape itself within integrated and related trends, even though the future of the company depends on keeping up or staying ahead of computer trends such as Edge Computer. In addition, speculative trades fared well because Dell shares increase by 2% to $13.12 while other technology giants like Microsoft shares declined.
The market assimilates information rather quickly. In fact, as soon as information is revealed of any firm in a certain direction, stock market prices react very fast. Moreover, the market commonly anticipates and reacts to information such as bidding before they are officially announced. The market has already incorporated expectations and speculations about certain restructuring into its price. Also, the market today is more efficient due to technological innovations which make it possible to share information instantly.
