Which type of irb review does not require an irb approval but does require a determination by the irb or an irb designee?

Physics

Westkost [7]2 years ago
4 0

Answer:

For this case the answer would be exampt. Since this is the only level that require a determination by the irb or an irb designee.

Explanation:

Previous concepts

We have 3 levels of the IRB review from the lowest to the highest:

Exempt. For thi slevel we have less than the minimal risk. And we have some examples like a survey with anonymous participants. And not classifed info. Other examples are: (Education research,  Surveys, interviews, educational tests, public observations (that do not involve children) ,Benign behavioral interventions ,Analysis of previously-collected, identifiable info/specimens ,Federal research/demonstration projects ,Taste and food evaluation studies).

Expedited. For this level we have more risk than th exempt level. An example would be analyze some info for non reasearch pruposes, but we can identify the subjects of the study. Other examples are :(Clinical studies of drugs and medical devices only when certain conditions are met , Collection of blood samples by finger stick, heel stick, ear stick, or venipuncture in certain populations and within certain amounts , Prospective collection of biological specimens for research purposes by noninvasive means , Research involving materials (data, documents, records, or specimens) that have been collected, or will be collected solely for non-research purposes , Collection of data from voice, video, digital, or image recordings made for research purposes )

Full board. That's the level with the maximum risk. Have included the identification of the subjects and the desire variable analyzed.

For our question:

Which type of irb review does not require an irb approval but does require a determination by the irb or an irb designee?

For this case the answer would be exampt. Since this is the only level that require a determination by the irb or an irb designee.

A potential difference of 53 mV is developed across the ends of a 12.0-cm-longwire as it moves through a 0.27 T uniform magnetic
Klio2033 [76]

Answer:

The angle between the magnetic field and the wire’s velocity is 19.08 degrees.                                            

Explanation:

Given that,

Potential difference, V = 53 mV

Length of the wire, l = 12 cm = 0.12 m

Magnetic field, B = 0.27 T

Speed of the wire, v = 5 m/s

Due to its motion, an emf is induced in the wire. It is given by :

\epsilon=Blv\sin\theta

Here,

\theta is the angle between magnetic field and the wire’s velocity

\sin\theta=\dfrac{\epsilon}{Blv}\\\\\sin\theta=\dfrac{53\times 10^{-3}}{0.27\times 0.12\times 5}\\\\\sin\theta=0.327\\\\\theta=19.08^{\circ}

So, the angle between the magnetic field and the wire’s velocity is 19.08 degrees.

On a hot day, the temperature of a 65,000-L swimming pool increases by 1.20°C. What is the net heat transfer during this heating
vichka [17]

Answer:

326149.2 KJ

Explanation:

The heat transfer toward and object that suffered an increase in temperature can be calculated using the expression:

Q = m*cv*ΔT

Where m is the mass of the object, cv is the specific heat capacity at constant volume, which basically means the amount of heat necessary for a 1kg of water to increase 1C degree in temperatur, and ΔT is the change in temperature.

A 65000 L swimming pool will have a mass of:

65000L *\frac{1m^3}{1000L} * \frac{1000kg}{1m^3} = 65000 kg

The specific heat capacity at constant volume of water is equal to 4.1814 KJ/KgC.

We replace the data and get:

Q = m*cv*ΔT = 65000 kg * 4.1814 KJ/KgC * 1.2°C = 326149.2 KJ

An object of mass 0.400.40 kg, hanging from a spring with a spring constant of 8.08.0 N/m, is set into an up-and-down simple har
sineoko [7]

Answer:

Acceleration will be equal to 2m/sec^2      

Explanation:

We have given mass of the object m = 0.4 kg

Spring constant k = 8 N/m

Maximum displacement of the spring is given x = 0.1 m

From newton's law force is equal to F=ma.....eqn 1

By hook's law spring force is equal to F=kx .....eqn 2

From equation 1 and equation 2

ma=kx

0.4\times a=8\times 0.1

a=2m/sec^2

So acceleration will be equal to 2m/sec^2
