B)The Sun is closer than Deneb
Answer:
Third and fourth diagrams correctly represent the forces as vectors.
Explanation:
The vehicles are pulling against each other, this means their force vectors must point in the opposite directions, so our diagram must have this property.
Looking a the first diagram we see than both force vectors point in the same direction, so this cannot be the right answer.
In the second diagram the force vectors have the same direction, but in direction opposite the previous diagram. This is also not a correct diagram for our situation.
In the third diagram the forces vectors point in the opposite directions and they have the right magnitudes ( 750N is smaller than 1000N vector). So this diagram correctly represents our situation.
For the fourth diagram the vectors point in the opposite directions and they have the right magnitudes; therefore, it is also a correct representation of the situation.
So we have got two correct diagrams: the third and fourth. <em>And we cannot choose between them because we do not know whether it's the truck or the car that is on the left or right. For example if the car was on the left the third diagram would have been chosen. </em>
This isn’t anything related to physics dude
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.
It totally depends on what kind of wave you're talking about.
-- a sound wave from a trumpet or clarinet playing a concert-A pitch is about 78 centimeters long ... about 2 and 1/2 feet. This is bigger than atoms.
-- a radio wave from an AM station broadcasting on 550 KHz, at the bottom of your radio dial, is about 166 feet long ... maybe comparable to the height of a 10-to-15-story building. This is bigger than atoms.
-- a radio wave heating the leftover meatloaf inside your "microwave" oven is about 4.8 inches long ... maybe comparable to the length of your middle finger. this is bigger than atoms.
-- a deep rich cherry red light wave ... the longest one your eye can see ... is around 750 nanometers long. About 34,000 of them all lined up will cover an inch. These are pretty small, but still bigger than atoms.
-- the shortest wave that would be called an "X-ray" is 0.01 nanometer long. You'd have to line up 2.5 billion of <u>those</u> babies to cover an inch. Hold on to these for a second ... there's one more kind of wave to mention.
-- This brings us to "gamma rays" ... our name for the shortest of all electromagnetic waves. To be a gamma ray, it has to be shorter than 0.01 nanometer.
Talking very very very very roughly, atoms range in size from about 0.025 nanometers to about 0.26 nanometers.
The short end of the X-rays, and on down through the gamma rays, are in this neighborhood.
