All are examples of speed except ______.

1 answer:

8 0

In the above examples, the only one that is not an example of speed is the option:
"6 miles per hour north". A speed doesn't have a direction added to it. If a statement has a direction added to it, it's velocity, not speed. Speed is a scalar quantity. In other words, it is the rate at which the object covers the distance. Speed does not care about direction. It is also not aware of direction. Velocity, on the other hand, is aware of direction and of speed.

ludmilkaskok [199]

Answer and Explanation:

Apical impulse is the place in the chest where the heartbeat can be palpated. The usual location depends on the morphological type of the person. In a normolineal individual, it is located at the intersection of the 4th or 5th left intercostal space with the left midclavicular line. This point corresponds to the area where the heart is closest to the costal grid thus allowing its palpation in an intercostal space. Usually lasts half of systole.
