Answer: It's A
conduct smaller studies for more than a one-year period
Answer:
Explanation:
Non conservative forces increase the entropy of the universe whereas conservative ones do not.
Answer:
Fk = 21.645N
Explanation:
Let Fb be Force of block and thus;
Fb= mg where m is mass of block and g is acceleration due to gravity
Thus Fb= 9kg x 9.81N/kg = 88.29 N
Now, the question says this force Fb rests at an inclined plane [email protected] 30° angle
Thus;
Force parallel to inclined plane = 88.29 x sin30° = 44.145 N.
Force perpendicular to the inclined plane = 88.29 x cos30 = 76.46 N
Now, when an object is falling freely, we know that
h = (1/2)at^(2)
From the question, the height is 5m and t= 2 seconds
Thus;
5 = (1/2)a(2)^(2)
2a = 5 and thus,
a = 5/2 = 2.5 m/s^(2)
Now, in inclined planes, perpendicular force - kinetic friction force = Resultant force
Thus let perpendicular be Fp and kinetic friction force be Fk and so;
Fp - Fk = F
F= ma = 9 x 2.5 = 22.5N
Thus, 44.145 - Fk = 22.5
Thus, Fk = 44.145 - 22.5 = 21.645N
Answer:
4. Personnel policies and programs
Explanation:
The Health care organizations that apply for Magnet status must demonstrate new ways of doing things and innovations in professional practice.
Personnel policies and programs is one of the forces of magnetism that impacts the structural empowerment of the organization.
The Personnel policies of an organization should provide an innovative environment in which the staff are developed and empowered. Empirical quality outcomes are reviewed by assessing the quality of care. New knowledge, innovations, and improvements are reviewed by assessing the quality improvement of the health care organization. Interdisciplinary relationships are assessed to review exemplary professional practice.
