Answer
Procedural bias occurs when the unfair amount of pressure is applied to complete their response quickly.
Measurement bias occurs when there is systematic or random error occur while taking the reading.
Design bias occur when the research fails to encounter all the aspects of the projects before presenting conclusion.
1) The correct answer is option B.
Balance is miscalibrated hence there will be systematic error which is a type of measurement bias.
2) The correct answer is option A.
Limiting response time for participant is an example of Procedural bias.
3) The correct answer is option A
Here, Jackie has not surveyed the diverse group so it is the case of design bias
For the given question above, there are other details that is missing. Here is what I got from my research.
Mass of a hydrogen atom as 1.008 u,
<span>where 1 u=1.661 times 10^-27 kg.
</span>The frequency of a mass on a spring is:
<span>f = omega / 2pi = sqrt (k/meff) / 2pi </span>
<span>The meff you use is the effective mass. If two bodies with mass M and m are both free to move: </span>
<span>Meff = Mm / (M+m) </span>
<span>If M=m, then Meff = m/2 (as you were given) </span>
<span>So the answer is: </span>
<span>f = sqrt (2k/m) / 2pi </span>
Newton's first law of motion is an object in motion stays in motion until acted upon by another force. Driving at 30 mph in a car is going to stay constant until you crash the car into a wall, stopping the car.
