Lena [83]

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.

Suppose that the speed of a ball moving in a horizontal circle is increasing at a steady rate. Is this increase in speed produce
lana [24]

Answer:

No.

Explanation:

Centripetal acceleration would make the ball move towards the center of the circle. Centri- means "center", -petal means "towards". But since the ball has its own velocity that is perpendicular to the centripetal force vector, the centripetal acceleration can only change the direction of the velocity. Which means that centripetal acceleration cannot increase the ball's speed.

A tennis ball rolls off the edge of a table. the table is 0.55m tall and the tennis ball lands 0.12m away from the table.
k0ka [10]

Answer:

v = 0.363 m/s

Explanation:

Given that,

The table is 0.55m tall and the tennis ball lands 0.12m away from the table.

Here, u = 0 (at rest) for initial vertical velocity as it rolls off the edge of a table.

Let t is the time to fall from the vertical height. So,

h=ut+\dfrac{1}{2}at^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\times 0.55}{9.8}} \\\\t=0.33\ s

It can be assumed to find the initial horizontal velocity of the tennis ball. It can be given by :

v_x=\dfrac{x}{t}\\\\v_x=\dfrac{0.12}{0.33}\\\\v_x=0.363\ m/s

Hence, the initial horizontal velocity is 0.363 m/s.
