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 justification for the problem is listed in the explanation section following.
Explanation:
The body requires D vitamin (hydroxycholecalciferol) from light from the sun, vitamin D is important throughout the minerals such as calcium by either the bones. Attempting to cover the entire body through garments leads to either little or no exposure including its body to sunshine, which also contributes to a loss of consumption of vitamin D even by the liver, which decreases the levels of nutrients by both the bones.
- Unless the bones accumulate calcium, individuals lose sufficient consistency, which increases bone strength which contributes to OSTEOPOROSIS, in which the bones becomes honeycomb formed and also very brittle, which fractures even without damage.
- Lowered absorption of calcium often triggers muscle fatigue because calcium serves as a binding agent in the active muscle mechanism.
- Calcium performs an essential role in the development of the parathyroid hormone. the intoxicated parathyroid activity also contributes to anxiety.
So that the above is the right answer.
Answer:the U.S. constitution preamble sets the stage for the constitution. It clearly communicates the intentions of the framers and the purpose of the document. The preamble is an introduction to the highest law of the land it is not the law. It does not define government powers or individual rights.
Explanation:
Answer:
Naturalistic observation, interviews, and case studies
Explanation:
Three of the most common research methods are naturalistic observation, interviews, and case studies. Each one of them brings something different to the table:
- Naturalistic observation refers to studying subjects directly on their environment without any intervention from the researcher. This is a great method because watching people behave in a natural way will be very revealing and more truthful. When subjects know they are being observed, they often change their behaviour. Naturalistic observation thus requires the observer to be as anonymous and invisible as possible.
- An interview is a research method where the subject is asked to answer to some specific questions crafted by the researcher. Interviews allow the researchers have a much closer look at the subject, trying to ascertain the motives behind their behaviour. However, a problem with interviews is that the subjects often time won't respond truthfully, but will adjust their answers to what is expected from them.
- A case study is a method that goes more in depth than the other two, and the researcher tries to learn as much as possible about the subject through a variety of other methods, like observations, interviews, surveys, etc. Case studies are much thorough and deeper investigations, but they can be very time consuming, and require a subject that is willing to facilitate the work of the researcher, which isn't always possible.
