Answer:
A. simple to construct and easy to repair
Explanation:
A dynamic microphone works on the principle of electromagnetic principle. A diaphragm is attached to a coil of wire which helps in producing sound. Responding to the sound waves, the coil of the wire is vibrated by the diaphragm. A magnetic field is created by the magnet which is present inside the coil of wire. The electrical signal is generated in response to the motion of the coil. The speed of the motion produces the amount of the current.
Since the construction of a dynamic microphone is easier as compared to any other microphone, John is likely to opt to build one.
Automobile repair shops produce many types of waste -- some hazardous, some not necessarily hazardous but still potentially damaging to the environment if not handled properly, and all requiring proper treatment and/or disposal at significant cost to the business. A list of the types of waste that the shop owner or manager must contend with would include:
solvents (paints and paint thinners)
antifreeze
scrap metal
batteries and other auto parts
oils and oil filters
fuels of various types
acids and alkalis (contaminated rags and towels)
Whatever the nature and characteristics of the waste may be, it all has one thing in common: All waste represents loss of resources and loss of money.
The computers found in DVD players, thermostats, answering machines, and some appliances are known as embedded computers.

Answer:
Explanation:
World Wide Web (www) has advanced as a major technology since its introduction during the 1980s. In beginning web sites were primarily used only by few number of users to share information related to their academic work. As the user interface evolved over the next coming years with each new version bringing in new frameworks and techniques, it powered web as a hub of technology. Web 1.0, 2.0 and 3.0 brought more dynamic features to the users. Web 1.0 used to describe the web content in static resulting in rigid user experience. Web 2.0 which powered social networking sites became popular developing the web which ultimately served as a platform for people to create and share their own content on the web in the form of blogs, wikis, feeds, tagging systems, user-created publication systems etc. The evolution of web technology began to spread its roots into the major business areas which brought in the requirement for high speed and expanded availability for substantial number of users.
On the other hand, Web 2.0 has also brought some security’s concerns. Mainly the component of client interaction with web, it opened doors to unauthorized actions in the application. In order to provide a rich user experience majority Web 2.0 sites have adopted lightweight user interface code such as asynchronous JavaScript and XML (AJAX). In the Conventional client-server models, many of calls (requests) are handled and processed on the server side. AJAX allows a higher percentage of requests to be processed on the client side. This may give malicious users many options to modify any application code running on a client machine by exploring and testing the application for vulnerabilities.
To overcome this objective, developers should consider installing an appliance at the Internet gateway, which performs real-time code inspection of traffic flowing through the corporate network. High performance and high availability appliances capable of monitoring and acting swiftly to block any suspicious web traffic are paramount. Also, it is very important that developers develop the application with security in mind. Following the coding convention, having the code reviewed, testing the application thoroughly are all part of securing the application in the web.
The answer is C. Use sarcasm and jokes in your e-mails to make the reader laugh
Sarcasm and jokes can be difficult to understand through text-based communication like e-mails, so it is best to avoid them altogether, especially in formal settings.
