Answer:
Spring constant, K = 415.9 N/m
Explanation:
The period of vibration of a spring, T, is given by:
T = 2√m/K
Where m = mass of the body in kg, K = spring constant or force constant or elastic constant or stiffness in Nm-1
Making K the subject of the expression,
K = m(2)2/(T)2
K = 4m()2/(T)2
Where m = 0.38kg, = 3.14285714286, T = 0.19s
K = 4 x 0.38 (3.14285714286)2 / (0.19)2
K = 4 x 0.38 x 9.87755102043 / 0.0361
K = 15.0138775511 / 0.0361
K = 415.9 Nm-1
Answer:
The answer is a positive correlation.
Explanation:
A positive correlation is found when the two statistical variables go in the same direction. In other words, there is a more = more or a less = less relationship.
In the example, <u>more poverty = more crime</u>. It's important to recognise that correlation is not the same as causation. The factors are related, but there is no solid cause-effect relationship.
Based on the thoughts of Keven, we can infer that this is a<u> hasty generalization fallacy. </u>
<h3>What is a hasty generalization fallacy?</h3>
- Coming to a conclusion about a population based on observations from a very small sample size.
- It is usually false and overblown.
Kevin came to his decision based on the small sample size of his grandparents alone. They are simply too small to account for the millions of older people out there.
In conclusion, option D is correct.
