Force(F), velocity (V) and acceleration (A). [3]

(B) The velocity V of a particle depends upon time ‘t” according to the equation

V=Vab + bt+<

Use Dimension analysis to determine the dimensions of a, b and e. What physical quantity does

each letter represent?

The most important consideration in Power Amplifiers is the collector terminal efficiency  

of the amplifying component. In practice, among all Amplifier classes, the class A common  

emitter Amplifier is the least efficient with the highest collector deficiency which results in  

a lot of power and battery consumption, that come with high heat dissipation requirements.  

Yet, the class A common emitter Power Amplifier when designed correctly, is the most  

widely used to handle large signals and delivers more power gain for outdoor hi-fi musical  

systems.

1. A particle with a mass of 3.8 × 10-20 kg is oscillating with simple harmonic motion with a period of 3.1 × 10-5 s and a maximum speed of 2.0 × 103 m/s. Calculate (a) the angular frequency and

1.      A particle with a mass of 3.8 × 10-20 kg is oscillating with simple harmonic motion with a period of 3.1 × 10-5 s and a maximum speed of 2.0 × 103 m/s. Calculate (a) the angular frequency and (b) the maximum displacement of the particle.

2.      A simple harmonic oscillator consists of a block of mass 3.20 kg attached to a spring of spring constant 140 N/m. When t = 2.00 s, the position and velocity of the block are x = 0.137 m and v = 3.040 m/s. (a) What is the amplitude of the oscillations? What were the (b) position and (c) velocity of the block at t = 0 s?

3.      A block of mass M = 6.20 kg, at rest on a horizontal frictionless table, is attached to a rigid support by a spring of constant k = 5570 N/m. A bullet of mass m = 9.60 g and velocity   of magnitude 570 m/s strikes and is embedded in the block (the figure). Assuming the compression of the spring is negligible until the bullet is embedded, determine (a) the speed of the block immediately after the collision and (b) the amplitude of the resulting simple harmonic motion.

4.      In the figure, a physical pendulum consists of a uniform solid disk (of radius R = 55.6 cm) supported in a vertical plane by a pivot located a distance d = 27.7 cm from the center of the disk. The disk is displaced by a small angle and released. What is the period of the resulting simple harmonic motion?

5.      The 3.50 kg cube in the figure has edge lengths d = 5.10 cm and is mounted on an axle through its center. A spring (k = 1300 N/m) connects the cube’s upper corner to a rigid wall. Initially the spring is at its rest length. If the cube is rotated 5.00° and released, what is the period of the resulting SHM?

6.      A block is in SHM on the end of a spring, with position given by x = xmcos (ω t + φ). If φ = 1.41 rad, then at t = 0 what percentage of the total mechanical energy is potential energy?

7.      What is the phase constant for SMH with a(t) given in the figure if the position function x(t) has the form x = xmcos(ωt + φ) and as = 4 m/s2? (note that the answer should be from 0 to 2π)

Critical Reflection Paper: Chapter 9

Objective: To critically replicate you’re thoughtful of the readings and your competence to rub on them to your Health care ethics.

ASSIGNMENT GUIDELINES (10%):

You need to read the article (in the additional weekly reading resources localize in the Syllabus and also in the Lectures link) assigned for week 1 and develop a 2-3-page paper reflecting your appreciative and ability to apply the readings to your ethics. Each paper must be typewritten with 12-point font and double-spaced with standard margins. Follow APA format 7th Edition, when referring to the selected articles and include a reference page.

EACH PAPER SHOULD INCLUDE THE FOLLOWING:

1. Introduction (25%) Provide a short-lived summary of the undertone (not a description) of each Chapter and articles you read, in your own words.

2. Your Critique (50%)

*What is your response to the content of Chapter 9?

*What did you absorb about Ethics and Safe patient handling? Mention and explain two examples where you can apply them.

* What are the ethics arguments for advocacy on SPHM programs and behaviors?

*For the Professional role you have right now: what are the implications of this chapter for you?

3. Conclusion (15%)

Fleetingly recapitulate your thoughts & postulation to your analysis of the articles and Chapter you read. How did these articles and Chapters impact your thoughts about the principles of ethics?

Evaluation will be based on how clearly you respond to the above, in particular:
