Explanation:

The given data is as follows.

   radius (r) = 10 mm = 10 \times 10^{-3} m   (as 1 mm = 10^{-3})

      \Delta P = 100 Pa,       F = ?

Therefore, formula to calculate force is as follows.

              F = \Delta P \times A       (as A = \pi \times r^{2})

so,          F = \Delta P \times \pi \times r^{2}

                 = 100 Pa \times 3.14 \times (10^{-2})^{2}

                 = 3.14 \times 10^{-2} N

Thus, we can conclude that net force on the blood in this section of artery is 3.14 \times 10^{-2} N.

A turntable has an angular velocity of 3.5 rad/s. A dust bunny is on the disk of the turntable at a distance of 0.2m from the ce
diamong [38]

Answer:

E. 0.25

Explanation:

Given that

Angular speed ω = 3.5 rad/s

Distance ,r= 0.2 m

Lets take mass of dust bunny = m

We know that

Radial force F = m ω² r

The friction force on the dust bunny Fr

Fr= μ m g

To getting slung off  dust bunny from disk

m ω² r =  μ m g

ω² r =  μ  g

3.5²  x 0.2 =  μ x 10                        ( take g =10 m/s²)

μ = 0.245

μ = 0.25

Therefore answer is E

E. 0.25

_____ life cycle models of systems development assume that the scope of the project can be articulated clearly and the schedule
Natalka [10]

Answer:

Predictive

Explanation:

 There is a wide variety of life cycles applicable to project management. In this regard, we currently have as a reference two somewhat extreme approaches that mark two very different ways of dealing with projects. The predictive approach and the agile approach.

  A predictive approach involves a great effort in initial planning and re-planning every time changes are accepted in the project. Therefore, this approach is recommended for changing but not highly changing environments. Although this approach is applicable to any type of project, clear examples of application would be the construction of a subway line, a bridge, the development of critical software. That is, projects where correct and detailed planting is key.
