Answer:
Efficent at low speeds.
Explanation:
Since water is 1,000 times more dense than air, electricity can generated from tides much more efficiently at slower speeds than wind turbines can.
Answer:
mechanical engineer is the best answer
Answer:
The answer for the question :
"Develop a chase plan that matches the forecast and compute the total cost of your plan. (Negative amounts should be indicated by a minus sign. Leave no cells blank - be certain to enter "0" wherever required. Omit the "$" sign in your response.)"
is explained in the attachment.
Explanation:
It is possible to generate a policy in which common points such as those mentioned above are agreed in order to hire or fire employees in their function of their psychological personality, that is, the character of knowledge and skills. Depending on the company, Test could be created in order to evaluate the psychological skills of the employees, as well as Test to periodically determine how their employees are kept up to date with regard to knowledge. The cumulative filter could be done every semester, for which each employee must exceed a minimum margin of score on these tests, otherwise his position could be at risk.
At the same time, incentives can be generated for the best scores that are rewarded not only with monetary values but also with rest days, coupons in restaurants or sports, which would cause the worker to strive to be constantly learning.
This policy agreement is outside the vision and mission of the company, and whose information must be given to the worker once he begins his work activities.
Answer:
a) 
, b) 
Explanation:
The Brinell hardness can be determined by using this expression:
Where 
and 
are the indenter diameter and the indentation diameter, respectively.
a) The Brinell hardness is:
![HB = \frac{2\cdot (1000\,kgf)}{\pi\cdot (10\,mm)^{2}} \cdot \left[\frac{1}{1-\sqrt{1-\frac{(2.50\,mm)^{2}}{(10\,mm)^{2}} } } \right]](https://tex.z-dn.net/?f=HB%20%3D%20%5Cfrac%7B2%5Ccdot%20%281000%5C%2Ckgf%29%7D%7B%5Cpi%5Ccdot%20%2810%5C%2Cmm%29%5E%7B2%7D%7D%20%5Ccdot%20%5Cleft%5B%5Cfrac%7B1%7D%7B1-%5Csqrt%7B1-%5Cfrac%7B%282.50%5C%2Cmm%29%5E%7B2%7D%7D%7B%2810%5C%2Cmm%29%5E%7B2%7D%7D%20%7D%20%7D%20%20%5Cright%5D)
b) The diameter of the indentation is obtained by clearing the corresponding variable in the Brinell formula:
![d = (10\,mm)\cdot\sqrt{1-\left[1-\frac{2\cdot (500\,kgf)}{\pi\cdot (300)\cdot (10\,mm)^{2}} \right]^{2}}](https://tex.z-dn.net/?f=d%20%3D%20%2810%5C%2Cmm%29%5Ccdot%5Csqrt%7B1-%5Cleft%5B1-%5Cfrac%7B2%5Ccdot%20%28500%5C%2Ckgf%29%7D%7B%5Cpi%5Ccdot%20%28300%29%5Ccdot%20%2810%5C%2Cmm%29%5E%7B2%7D%7D%20%20%5Cright%5D%5E%7B2%7D%7D)
