For TQM to be successful, the organization must concentrate on some of the key elements which will improve a quality programme within an organization and move the organization towards Total Quality Management. Evaluate 5 of these key elements in achieving a successful TQM implementation.

let L be a double integral

L 3x^(2) dA ;(R) is bounded by y=0, y=6x+12, and y=3x^(3)

a car is experiencing an acceleration of 2.0 m/s^2. if the driving force of the engine is 15000 N and the cars mass is 700 kg, what is the force of friction acting on the car?

Using a difractometer and an x-ray source having a wavelength of 1.54 A degree one peak is observed for first order reflection from an FCC material when 2theta is 121 degree.

Write a Python function to find the maximum of three numbers.

A pendulum with a cord of length r=1.00 m swings in a vertical plane. When the pendulum is in the two horizontal positions θ = 90º and 270º, its speed is 5.00 m/s.

(a) Find the magnitude of the radial acceleration and
(b) the tangential acceleration for these positions.
(c) Draw vector diagrams to determine the direction of the total acceleration for these two positions.
(d) Calculate the magnitude and direction of the total acceleration at these two positions.

A meter stick is pivoted at its 50-cm mark but does not balance because of nonuniformities in its material that cause its center of gravity to be displaced from its geometrical center. However, when weights of 150g and 200g are placed at the 10-cm and 75-cm marks, respectively, balance is obtained. The weights are then interchanged and balance is again obtained by shifting the pivot point to the 43-cm mark. Find the mass of the meter stick and the location of its center of gravity.

Case (IV)
With the suspension point 30cm from the left edge of the meter stick, hang a 200g mass 10cm from the left edge of the stick. Calculate the mass you must hang at a point 40cm to the right of the pivot point such that the stick hangs level and write it on the sketch.

You are driving to the grocery store at 24 m/s. You are 130 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.50 s and that your car brakes with constant acceleration.
a) What acceleration (magnitude) will bring you to rest right at the intersection?
b) How long (total) does it take you to stop after the light turns red?

You have a summer intern position at a laboratory that uses a high-speed proton beam. The protons exit the machine at a speed of m/s, and you've been asked to design a device to stop the protons safely. You know that protons will embed themselves in a metal target, but protons traveling faster than m/s emit dangerous x rays when they hit. You decide to slow the protons to an acceptable speed, then let them hit a target. You take two metal plates, space them 2.1 cm apart, then drill a small hole through the center of one plate to let the proton beam enter. The opposite plate is the target in which the protons will embed themselves.

1.What are the minimum surface charge densities you need to place on each plate? 

2. Which plate, positive or negative, faces the incoming proton beam?

A cyclotron designed to accelerate protons has an outer radius of 0.330 m. The protons are emitted nearly at rest from a source atthe center and are accelerated through 600 V each time they cross the gap between the dees. The dees are between the poles of anelectromagnet where the field is 0.550 T.

Which medtech business strategy— first mover, fast follower, me-too, niche strategy, or distribution strategy—seems most appropriate in the following situations:

The competitor has beaten you to market with a technology that you believe you can make better with expanded features

All other competitors are trying to address the mass market, but interesting untapped segments remain unaddressed.

Although the competition’s technology has some novel features, the depth of your bundled multiple product offerings will make it very difficult for them to penetrate

You have limited R&D expertise, but know enough to reverse-engineer well and you believe no strong IP exists to prevent you from entering the market

There seems to be no competition in a large field for the product segment.

A. Me-too

B. Niche strategy

C. Distribution strategy

D. Fast follower

E. First mover

Determine the volume (m^3) necessary to fill with hot air for a hot air balloon to lift a payload of 800 kg. Assume that the temperature inside the balloon is 99.0 C and the temperature outside is 20.0 C. Assume that the pressure (inside and out) is 1.00 atm and that the molar mass of air is 28.9 g/mol.

A business plan or pitch should be used as a tool for:

a. Planning the required steps for the company to bring its product to market and become financially viable

b. Declaring and monitoring important goals, according to a specific timetable

c. Framing and guiding communications, both internally and externally

d. All of the above

A balloon is filled with hydrogen gas and produces the followingchemical reaction between iron and sulfuric acid: Fe(s) + H2SO4(aq)--> FeSO4 (aq) + H2(g). If the balloon had a volume of 4800cubic meters and was filled to a pressure of 1 atm at a temperatureof 0 degrees C, a) what mass of iron (in kg) and how many moles ofsulfuric acid were required to fill it? b) If the total mass thatcan be lifted by a balloon is equal to the difference between themass of gas in the balloon and the mass of air displaced by theballoon, how much mass could by lifted by this balloon and how muchmass could the same balloon lift if it was filled with helium atthe same pressure and temperature. c) using the barometric formulaP= P(initial)e^(-mgh/kt) to estimate the height to which theballoon with a payload of 1000kg can rise when filled withhydrogen. (The balloon will rise until its density equals that ofthe surrounding air) Assume the the temperature of the air does notchange with the altitude. Use an average molar mass for the airbased on 80% N2, 20% O2.
