Answer: time t = 10s
Explanation:
Given;
Diameter = 8.0cm = 0.08m
Radius r = diameter/2 = 0.08/2 = 0.04m
Cord length d = 6.0m
Angular acceleration = 3.0rads/s2
Time = t
Converting the angular acceleration to linear acceleration
a = a* × r = 3.0 × 0.04 = 0.12m/s
d = vt + 1/2 (a × t^2)
Initial velocity v = 0, vt = 0 therefore;
d = 1/2 ( a × t^2)
t = √(2d/a)
t = √ [(2× 6)/0.12]
t = 10s
Answer:
Option A
interpreting results
Explanation:
In a Scientific research, we first formulate and test hypothesis of the study. A hypothesis is a tentative guess in the study which should be validated in the process of the study. We may have a null and alternative hypothesis. After formulating the study, we conduct the actual study where we get raw data. The raw data is then analyzed, in many cases using statistical analysis tools such as R, python, excel spreadsheet etc. Therefore, the next step after formulating and objectively testing hypotheses is to interpret the results.
