Answer 1

7.

An actuator is a component of a machine that is responsible for moving or controlling a mechanism or system, for example by actuating (opening or closing) a valve; in simple terms, it is a "mover".

An actuator requires a control signal and a source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic or hydraulic pressure, or even human power. The supplied main energy source may be electric current, hydraulic fluid pressure, or pneumatic pressure. When the control signal is received, the actuator responds by converting the energy into mechanical motion.

An actuator is the mechanism by which a control system acts upon an environment. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), a human, or any other input.

Correct answer is - option E.

8. The correct answer is option D. Identifies spread of dataset.

10. The correct answer is option A.

Standard Deviation The standard deviation (sigma) measures how spread out the data is . A simple formula for calculating the standard deviation is: Sigma = squareroot 1/n-1 sigma = 1 (x_i - mu)^2 The following example shows hoe the standard deviation can be calculated. sigma^N_i = 1 (x_i - mu)^2/N - 1 = 7176.5/9 = 797.3889 Sigma = squareroot sigma^N_i = 1 (x_i - mu)^2/N - 1 = squareroot 797.3889 = 28.238

Whether we recognize it or not, we all deliver informational messages on a regular basis. We run into trouble only when the information is fairly complex or when the situation is formal. Most informal presentations use a form of narration—storytelling—and chronological and descriptive patterns of organization that conform to the way most people observe and remember things. This is essentially the form we use when we answer such questions as “How was your weekend,” or “What did you do on your vacation?” For this reason, narration and description are what we do naturally and comfortably.

Effective use of the chronological pattern, however, requires that we keep the following guidelines in mind:

1. Include the Audience. Because your stories are based on your own observations and interests rather than on those of the audience, you need to make a special effort to emphasize those points of greatest interest to the audience.
2. Use Explicit Transitions. Unless you make transitions between ideas and time references absolutely clear, the chronology will not be clear to the members of the audience. Use appropriate transitional words to clarify relationships for your audience (next, while, at the same time, two weeks later, etc.) so that your audience will be able to follow your story.
3. Make a Point. A story needs an identifiable point or message if it is to have meaning for the audience.
