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

Why do you think it benefits people to have brains that are flexible? what would happen if brains were not flexible?
Sati [7]
If a human brain is not flexible, it will be a lot more limited than it already is. In another way of looking at it, you can even say that if it does not expand, it is only a box or a storage. Our brains do not only work as storage of information! We also use our brains for thinking etc. If it is rigid, when a lad hit you accidentally on the face with a paper, you may resort to violent retaliation.

Brains should be adaptable on the grounds that on the off chance that they weren't we could never have the capacity to expand our astuteness. Individuals are more adaptable mentally on the grounds that we can turn our hands to more mind boggling things and can learn better.

Mars2501 [29]

This is true. The specific u.s. department of health and human services (hhs) regulations that apply to research with children are known as subpart d: additional protections for children involved as subjects in research.

<h3>What is the protection of children as research subjects?</h3>

This has to do with all that has to be in place if children are to be used as participants in a research study. One of this would be to first get consent from the parents of the children. Due to the fact that the children cannot give consent on their own, their parents would have to sign a permission slip first.

Hence we can say that  The specific u.s. department of health and human services (hhs) regulations that apply to research with children are known as subpart d: additional protections for children involved as subjects in research.

Ronch [10]

Compared with Great Britain's obligations, the expense of the Indian and French wars to the homesteaders had been slight. The pilgrims who ostensibly delighted in a better quality of living at the time than their British partners paid short of what one-twentieth the expenses of British residents living in England.

I have been living in these harsh occasions. They are attempting to fabricate a likeness of King George utilizing our income that we endeavored to work for. We tried to use a blacklist to attempt to get a goal to the statue; however, it was revoked immediately.
