Answer: 2.19 seconds
Explanation:
<u>Given:</u>
Initial speed, u = 0 m/s
Acceleration of the boat, a = 5 m/s^2
Distance between the boat and dock, d = 12 m
Using the third kinematics equation to solve for time:
d = u*t + (1/2)*a*t^2
12 = 0*t + (1/2)*5*t^2
t = sqrt (12*2/5)
t = 2.19 seconds
Therefore, it will take the boat approximately 2.19 seconds to reach the dock
The surface of the table and brick may not match up perfectly. This means that friction may occur leading to the brick slowing down or some bit of heat resulting from the contact.

Answer:
t = 6.68 seconds
Explanation:
The acceleration of the automobile, 
Initial speed of the automobile, u = 91 km/hr = 25.27 m/s
Final speed of the automobile, v = 104 km/hr = 28.88 m/s
Let t is the time taken to accelerate from u to v. It can be calculated as the following formula as :
t = 6.68 seconds
So, the time taken by the automobile to accelerate from u to v is 6.68 seconds. Hence, this is the required solution.
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
