Which type of inappropriate practice most likely occurred if a researcher takes credit for someone else’s idea and does not ackn
Rashid [163]

Answer: the answer is plagiarism.

Explanation: Plagiarism is the act of taking credit from someone else's works or ideas, without acknowledging the author. <u>Conflict of interest</u> occurs when an employee has <u>interests that are at odds to each other</u>, which isn't shown at the excerpt given in the exercise. <u>Fabrication</u> is the <u>creation of intellectual property</u>, also not shown in the exercise, and <u>falsification</u> is the <u>creation of a scientific hypothesis</u> that <u>cannot be verified</u> by lack of practical evidence, which is not the case described as well.

The viscosity of a fluid is 10 be measured by a viscometer constructed of two 75-cm-long concentric cylinders. The outer diamete
a_sh-v [17]

Answer:

0.023 Pa*s

Explanation:

The surface area of the side of the inner cylinder is:

A = π*d*l

A = π*0.15*0.75 = 0.35 m^2

At 200 rpm the inner cylinder has a tangential speed of:

u = w * r

u = w * d/2

w = 200 rpm * 2π / 60 = 20.9 rad/s

u = 20.9 * 0.15 / 2 = 1.57 m/s

The torque is of 0.8 N*m, this means that the force is:

T = F * r

F = T / r

F = 2*T / d

For Newtoninan fluids with two plates moving respect of each other with a  fluid between the viscous friction force would be:

F = μ*A*u / y

Where

μ: viscocity

y: separation between pates

A: surface area of the plates

Then:

2*T / d = μ*A*u/y

Rearranging:

μ = 2*T*y / (d*A*u)

μ = 2*0.8*0.0012 / (0.15*0.35*1.57) = 0.023 Pa*s
